Hi all,
I'm currently experiencing a problem where my Softbank X01ht drops off the cellular network because I live in a low strength area, and takes forever, if at all, to automatically connect back to the network, even if I move into an area where I know the cellular strength is high.
If I manually turn off the phone portion of the hermes, and reconnect, then it happily detects the cellular network and connects. In other words, after disconnecting, it acts as though there is no network in range at all, even though I know there is.
This seems to have started after I upgraded my radio rom to version 1.20 from 1.07. Prior to the upgrade, I know it connected back to the network quite quickly after it dropped out. Has anyone else experienced this with the 1.20 Radio Rom? I currently have the Imate jasjam rom installed on my phone with the 1.04 bootloader.
Unsure if this is related, but the area that I live in has a weak UMTS network, but a relatively decent GPRS network. I'm thinking the phone is getting confused over which network to connect too.
It also seems that if I'm in an area with a pretty strong cellular strength, it doesn't drop out? Would I benefit from downgrading to the 1.16 Radio Rom?
Thanks in advance all.

I can also confirm that things added with that after a soft reset sometime it cant detect network..i have to manualy turn off/on the radio part....generelly it occures if i reset the set just after making a call or just getting disconnected from edge...
the previous 2 radio that i used 1.16 and 1.08 didnt suffer from those probs...
but the main benifit of 1.20 radio that i get is EDGE speed i can pump upto 220Kb (22-24 KB) download speed in flat when connected to pc as wireless modem but with the previous radios i can barely go 160Kb and the speed did uped/down regularly...
and somewhat strange with this 1.20 radio i cant search for network list manually when even i go to manual in network after sometime i get cant read error...but previous radios where ok in that par too...
and the last benifeat that i get with 1.20 is now the SIM STK menu is working.....

Thanks sajib,
Glad I'm not the only one experiencing it. For me, however, it only occurs when it looses connection to the cellular network. After every soft reset so far, it has connected to the cellular network automatically. To me it doesn't seem to even search for the network. That is, after loosing connection, it is resigned to the fact that it can't connect to a network, so doesn't even try, unless I force it too. I think I have seen it connect automatically once or twice, but either way, it takes at least 10-20 minutes, sometimes it never connects, and I force a manual reconnect by turning off the phone and turning it back on. So is this a known problem with the 1.20 Radio Rom?
Try this...
I had the same problem on my TyTn. Took forever to WiFi connect. Then I found this registry setting:
[HKLM\Comm\TIACXWLN1\Params]
"dot11ShortPreambleInvoked"=dword:00000001
Now my WiFi time-to-connect seems much faster.

Hi!
Thanks for the advice, but mine isn't a Wifi problem, but a problem with connecting to the cellular network.
Or do you think that your connecting to the WiFi network and the cellular network are one in the same?
i am using the 1.20 radio as well, but cant say that i have had any of the said problems... i have the cingular 8525 and have used the 2 latest cingular roms, the aku2.3 and 2.6.. but i did have some of the same problems with i used cingulars 1.16 radio

Do you commonly get cellular network disconnects? I find that if I'm moving around the city or driving around in the car, the network connection is maintained, and sometimes will automatically find the network if it does get disconnected. However, it is only when I am home that the phone disconnects and doesn't try to reconnect once it has been disconnected.
Any idea of what might have caused this issue with you with the 1.16 Radio Rom? Possibly something to do with the AKU version? I'm using AKU 2.3.
Thanks,
Gene

I too have the original problem but have not upgraded the radio ROM. I have the T-Mobile Vario II (sorry not sure what ROM that is) but often when I move from an area of either very weak or no signal to an area with a signal (coming out of a shielded building) I too get the same problem. Initially the phone shows weak (or even strong) signal strength but when I try to make a call I get the box up on the phone screen telling me it cannot connect. I have found that eventually it will, when left to it's own devices, get itself sorted out and allow a connection. But it is invariably quicker turing off the phone (via comm manager) then back on - this always results in a valid connection.
Perhaps the problem that you describe is not related just to the 1.20 Radio ROM upgrade?

Hi Tony,
It could possibly be an application or the ROM itself causing the problem, however, I think its the radio rom in my case, simply because this problem only started occuring after I upgraded to the 1.20 Radio Rom. Previously on the 1.07 Radio rom, the phone would connect automatically and immediately. Also I just performed a hard reset after I discovered this problem, and it still seems to be occurring...
I also am sure that after a long while the phone reconnects, I have seen it try reconnect a couple of times. But then again, a couple of times I've left it for 10-30 minutes, and it hasn't reconnected. Unsure of exactly how it chooses to reconnect and when it tries to reconnect. You would think it would try reconnect constantly after a specified period, but in my case it seems very random.

i actually get pretty solid coverage whether moving or stationary. especially at home since i live not a quarter mile from a cingular tower and i dont think its necessarily related to the aku version since i have gotten the same result with either 2.3 or 2.6. But i can say for sure that the cingular 1.16 radio is junk my biggest complaint was gsm calls cutting out and on my calls on 3G had a very weird digitized background noise, kinda sounded like a bad digital echo... 1.20 fixed all of that for me

When I'm roaming around my connection always seems to be sustained. e.g, I've been checking my phone ever 1hour for about 24 hours, and have yet to see my signal lost. Is it possible that the phone is getting confused over which band to connect to? As I said in my first post, I have a relatively weak 3G/UMTS signal from my home (1-2 bars), and a relatively strong GPRS signal (3-4 bars). Presumably the phone is UMTS-preferred, and uses GPRS as a secondary.
I saying this, even if I go to another area which usually has 5 bars UMTS signal, I haven't seen the phone immediately connect. This was after about 10-15minutes waiting in that area.

yes, the phone is set to prefer the UMTS bands.. have you tried setting the band manually instead of it letting it autosearch? you can do it in the phone settings menu or use the app listed here: http://forum.xda-developers.com/showthread.php?t=286844

Flash HardSPL first, then upgrade your radio.
Ive linked to my guides incase your unfamiliar with the process.
The newer radio should possibly increase your GSM efficiency. Are you in a decent area for reception?

Hi, many thanks for your detailed guides. I've upgraded Radio to 1.38.00.10 but the problem still persists. I'm in a very good coverage area, always get full bars 3G when it works. Soft-reset my phone and now it's searching in vain for network signal, I'm confused
What operator are you with ? Maybe the cell where you live is getting overloaded. We had a problem similiar to this last month when our local base station had a problem. Our work-around was to disable 3G but not using a Hermes . Apparently the handset tries to register using the 'best' data-bearer its configured for. So disabling 3G made it register with GPRS which worked fine. They then fixed the base station and we were able to re-enable 3G. I would
guess Charlton would have a lot of subscribers per cell. You would expect the coverage to be better in a built-up areas but who knows. Maybe an enquiry/ complaint to the operator would at least tell you if they know of a problem and if its temporary or longer term
Cheers for that. I'm with T-Mobile. What's bugging me is that this signal disappearance only happens sometimes. It's not that I don't have 3G (or signal for that matter) at all, I still get full 3G signals fine most of the time. But you probably were right, looks like it's a fault from the operator's cell in the area, I will give them a call next week to see if there's an explanation.
I've noticed this problem when I'm in the south London area (very general I know). People have got around the issue temporarily by forcing the phone to GPRS only
More problems! After upgrading to 1.38 and trying all sort of "good" radios like 1.17, 1.27, 1.34 I can't make/receive calls unless GSM is forced. There must be something wrong within my immediate area because with the same radios everything works flawless just 10 mins down the road. I just called TMob and there's no technical fault or anything from their side. I will just have to put up without 3G until the problem fixes itself
There are lots of people complaining about 3g on T mobile in UK. They seem to have serious issues with Hermes devices and the dropdown to GSM.
I had a problem six months ago with my hermes on orange at home in SW London. For a few weeks it was mucking about - I rang O who advised me that they were experiencing some local issues but would fix them within days. I switched to GSM for a few days. When I switched back its worked fine for last five months.
3G gone mad!
the same thing was happening to me. Full 3G reception in Leicester, tried to connect to get my e-mails and then the signal totally goes. The same thing happens when I make calls as well. Switched to GSM and everything worked. Now in York and everything is working on 3G.
Network is T-Mobile.
This sounds similar to the issues I am having.
Do you get the phone hanging as it attempts to start a call and then after a while a message stating that it was unable to connect?....sometimes resulting in a soft reset to bring the device back online? In my case toggling bluetooth will reset the connection.
I am with T-Mobile in Glasgow but get the same issues during the day in Edinburgh
No 3G

No mine doesn't say anything, it sounds "ding ding" after a few secs like when you press the hang up button. I can use the Internet but anything to do with calls is just impossible. I've switch to GSM now and everything's back to normal. A bit annoying can't use 3G at home.
hey guys...this is my first post here...
my pda2k keeps on dropping signals and sometimes halt during a call...
at first.....as instructed..2 time restarting solved the problem..
can you guys plzz help me out.......im using wm6
thnx in advance
What version of Radio do you using ? Try to upgrade to the last version.
my BA info is as follows
ROM version 5.60.00 WWE
radio version 1.12.00
well from where can i get the latest version of radio??
wel..i found it..and i am upgrading radio...
less see what happens
.....upgraded to 1.15.00
....no success......
im not the first one to have this problem..it ws in 2003. 2005 and now in wm 2006 now....
dunno what to do.....dont wanna throw away my pda2k
Maybe it is an hardware problem?
If your problem is in WM2003, WM5 and WM6, just get the phone to a repair or a recycle center....
but the thing is ..it was working fine....
and after installing a resh rom...it works for like 2 days with no problem...
im sure that its not hardware issue....
its the same problem....which everyone esle is having in this forum..abt signal dropping...dun think tat this harware problem can come to lot ov ppl at the same time...
the problem is with the phone company...
my pda2k also gives me similar problems...
but when i'm travelling to some other countries and using a local sim card there... i do not see any such problem... even while roaming sometimes... i do not see any problem with the current sim card.
i think it is the home service provider which has the problem.
If you have signal dropping, replace the flex cable.
The flex cable signal dropping is a common problem to any slide phone.
In fact I slide the phone halfway to test the signal if it will drop or not.
No signal drop means good flex cable.
Same case with Nokias and other phones.
I've had my friend's BA flex cable replaced and signal drop is solved.
also, one old battery can do that issue.
with my older battery, it used to cut connections sometimes. with the new one, keep connection.
hmm...but the thing is...that this fone was working fine in my country i.e Pakistan..but its giving problem here in canada.......and it actually came from canada before....
i dont know what to do....there were also issues like that with my imate-Pocket pc before...and now same is with PDA2k...
i have chaged a lot of sims...but no success.......
I personally believe that there is a bug on the radio dll.
If you are using WM2003, try this workaround to see if it helps: http://forum.xda-developers.com/showthread.php?t=340557
In your case, activate only the 1.900Mhz band or the 850 / 1900 band only. I believe that the former is better, though.
I've been only using it for the last 2 days, but so far so good.

Well same problem here in Bulgaria. We have 3 Telecoms. Unfortunately i have subscription to one of them and some times like every couple of months I have the same problem. Green light blinking, but when someone is calling me - out of service. It rings, but after i pick up - it drops the call and gives "No service" This last for about a day or so. When i switch sim cards to another service provider - it works fine. The same thing happens when I travel from one town to another. I thing this is due to poor software configuration in the GSM towers. Overall for three years this happens to me like 10-15 times for couple of hours to one day. And I have this problem only with one provider only. No work around as far as i know.. Sorry
signal problem partially solved.

Guys,
Definitely the problem is software. I'm from Brazil and my operator is TIM. I tried many ROMs (at least 10) with the same symptom: if the phone misses the signal, I get into troubles to find the signal again and it keeps finding another operator instead TIM (in my case it only finds Vivo - which is 850Mhz).
After those many trials, I found a ROM that solves the problem partially. It's the PV DVH 19701 ( http://forum.xda-developers.com/showthread.php?t=390008&highlight=19701 )
With this ROM, it still looses the signal when on a place where the signal is not present and don't find while returning to a place which the signal is present, BUT, I just tap the antenna on the top of the screen, tap settings > network and finally tap "find network" and VOILA, the signal is back without much pain!!
One more thing is a little change on the registry according to a recommendation from Microsoft. Using one registry editor, go to:
HKCU\ControlPanel\Phone and change the value for "Features" parameter from 204c7d8 to 206c7d8. Remember that before you change, you need to choose the view mode to hexadecimal.
That's it folks...have fun!
I am experiencing a very strange problem, and I really hope to solve it otherwise I will have to use my blackstone just as a PDA...
Something like one week ago I have experienced huge problems to catch network, I was at my home where there are always problems as it is located on the border between Luxembourg and Germany, several networks are available and no one is really ok.. however in the past expecially after radio 1.13 all was more or less solved but after "that" moment it was extremely difficult to connect, even with the "manual"option while in the past it was always ok and even if connected with signal at a good strenght it was impossible to make any call or connect to data network.
At that moment, I had Topix 2.6 with radio 1.13 - I have tried to reinstall the image, I have changed to Topix 2.7, then to Dutty 3.5, radio 1.14, back to 1.13... hard reset several times... no way to solve and symptoms are exactly the same.
At least I have identified the problem in transmission: reception is ok, phone can "see" networks but as I try to connect he cannot negotiate, when signal is stonger all works fine, and when it start to become weaker (for instance entering into a garage) I can still hear perfectly but people cannot hear me... assaid also even if I see a decent signal I cannot make any call, I can receive but when I try to answer I cannot say anything (I hear people but they cannot hear me at all)
So my question is:is there any "bios-like" settings that may influence the transmission power or I have to pre-pension my beloved blackstone... ?
All the rest works just perfectly...
Thanks for your he
Eventually does someone know if the tx and rx antennas are the same? Just to see if eventually it can be an internal damage to teh tx antenna...
Thanks for any help!
I hope you will forgive me for an up...
I had to put Blackstone in a drawer, it is impossible to use it unless the coverage is perfect...
seems you have a motherboard problem, what is your SN? 845 have gsm chipset

I think this is absolutely normal if you are in low reception area. The phone (2W EIRP max) can not compare with the TX power of a base station (~1000W EIRP), so if there is a problem with the reception you shoud still be able to 'hear' the base station but the base station may have trouble 'hearing' you. It is not neccessary to have sepparate antennas for TX and RX, so it is safe to assume that the blackstone's antenna is the same, so the problem is not with your antenna. Still, you may try to see the RX level on your phone using the fieldtest application (search in XDA). Be sure to launch it during a call because the BTS is likely be configured to use the 1800 frequencies for calls (if available) and 900 mainly for signalling.
As for a tweak or application for boosting the TX power of the phone, I seriously doubt that there is one, because this is defined in the GSM standard and is controlled by the BTS, so the phone has little to say about it.
You can try to search for an application that forces the phone to identify itself as a 900 GSM only (unfortunately in the band setting there is no such option) and see if the problem is with the 900 -> 1800 'handover' when you make a call.
Of course you may try speaking to your operator's support and ask them to make some tests - like shutting down the 1800 frequencies of your cell in the middle of the night and trying to make a call, but it is highly unlikely that they will be willing to do that. Or even demand that they install some kind of repeater to cover your area.
Thanks guys, really appreciated!
Unfortunately however the problems looks really like the phone became "weaker" as, in the same area" after this "something" was really ok, better than the Diamond especially with the last radio releases. Network is there, and if it is not, is because the phone cannot "negociate" correctly its login onto (I am in the border between Germany and Luxembourg and there are quite few network but especially T-mobile was always ok if connected manually).
When i manage to connect it stays ok, I can hear everybody but they hear me "broken:
as soon as I am at home i will check the serial- I really think I will have to take to the doctor, hoping that is recoverable (it should be in warranty however...to be checked)
Just make sure you flash the original ROM with which the device came, because there have been numerous cases when HTC blames everything on the custom ROM and refuses to repair the phone.
Hi guys, i know this is a common problem amongst some of us, there are several threads discussing the connection drops but please there must be someone out there who knows something about it.
Basically with HSDPA enabled, the connection will last a random period of time before disconnecting by itself and displaying: cannot connect for an unknown reason.
When HSDPA is turned off, only 3G is used, although this works fine, it is fairly slower.
I am on T-Mobile UK, I have phoned their technical support, we have established it is not the sim card but the phone itself and have tried a variety of steps to solve this, for example receiving band settings for WCDMA, this has not fixed the problem.
I have tried changing the username and password combinations and have tried every combination of every advanced network option. I have used the T-Mobile stock rom 1.43, official HTC ROM 1.66, duttys hg, energyROM, artemis 5.0 and artemis 5.5 (would recommend btw) using MTTY before every flash, and every single different radio combination.
Myself, and many people here would be very grateful for any help posted.
Thanks in advance
Why don't you try Settings > Connections > Advanced network > GPRS tab > change from PAP to CHAP.. and reset... or viceversa.. that helped for me..
Thanks for the post, i've tried all that i've tried all advanced settings, at most they last for a day or so but after a while the connection dropouts seem to worsen
Ok ive just gotten off the phone for the third time with the technical support
basically what they've said is that the hsdpa WILL disconnect because the mobile towers simply can't handle the traffic.
He said in his honest opinion I should disable it because it simply won't work well and there is no fix.
Taking the piss juuuuust a little bit
Mine on t-mobile uk will show H, but usually drop down to 3G. It won't give me an error when it drops down though.
It sounds like its not transferring from H to 3G.
To be honest, i was unaware t-mobile ran HSDPA till I got my HD2 (never showed on my BB).
mine switches between 3G and H too, this happens when the connection is being used (for example loading a web page) when the job is finished (page has finished loading) it turns back to 3G right?
are you saying that your connection never disconnects?
may i ask which radio and rom you are using?
thanks!
For my personal experience, I have for over a month, on versions 1.48, 1.66 by HTC, artemis versions, versions of other French chefs. had no problems,
Login Exchange push 24/24 without any cuts, I solicited the network with opera I passed automatically 3g H, and since February it to completely fall with the problems that everyone encounters (lost connection for several minutes , unable to connect to 3G without hard reset)
to remove the sim chip, I try with another chip of the same operator, another chip from another operator, the problem is still there.
For several days I have also continued a Touch HD, it faces no problems, no problems in connection 24/24.
In short, impossible to challenge any operator, any base station, any sim card.
It is then that the problem come from HD2:
-Software: We all try every combination of rom and radio rom possible.
It is the hardware, maybe the chip integrated into a concern for design, manufacturing concerns on some series, may be dysfunctional due to incompatibilitée between several chips of the phone, short, HTC should look into the problem.

correct, it never disconnects.
It will switch seemlessly between them, when using or not using.
same one it came with. O2 HD2.
ROM 1.43.206.4 (70315) WWE
RADIO 2.04.50.22_2
I've also been struggling with this problem ever since I got my HD2 three weeks ago. However it seems like only a few people experience this.
My case is exactly like cgrec92 described. I'm on a 3.5G network in Denmark (3 Mobile), the phone shows the 3G connection at all times. When things do work and I use Opera/weather/Twitter/email etc, the symbol changes to H and I know the data connection is functioning. I can be using this for a whole hour without any problems.
However, if I put the phone down for a while and then pick it up again to use one of its data services, very often it does not connect to 3.5G (or H) anymore. It will still show the 3G icon on the screen, but there's no data connection. Then I go to Connection Manager and I can see that data connection shows as Off - and after a few seconds it goes back to On by itself That does not mean the problem is solved, as the phone still fails to establish any data connection. What I need to do then is manually turn off data connection and re-enable it again, which makes the 3G symbol immediately change to H. Then everything starts working again - until the next time it stops working...
I contacted the HTC customer service and they said it might be a driver-related issue, recommended a hard reset. I did that and for a few hours I thought it solved the problem, but no, data connection still disconnects by itself.
I spoke to 3 Mobile's technical service and they told me to update my software, which I had already done previously (I'm running stock 1.66 ROM Danish). They also said they never received any such complains about the HD2.
Like cgrec92 I've also played with all kinds of network/band settings, but it did not make any difference.
***
One question: isn't the phone supposed to automatically connect via EDGE when it cannot connect via HSDPA? Because in my case it will only establish data connection via H, never EDGE.
Any advice is greatly appreciated!
My take on this FWIW
It's not the phone!
It's the radio ROM installed.
I live in an an area where T-mobile say I can't get HSDPA.
However, I know that I can. How? Because 3 network uses the same local cell and transmitter as T-mobile and their signal will rip your eyes out!!!!!!!!!
All information obtained from a good friend of mine who works for BT, who, service manage the cells for the networks.
Plus, in this location, the cell traffic is then handled by BTs digiatal backbone which takes it who knows where after that.
So I have a very isolated situation in which I know there is a decent HSDPA signal, but I have had trouble with drop outs on my two previous phones (Nokis 5800 and HTC Touch Diamond 2) and originally on my two T-mobile mobile broadband feeds using Huawei E220 cell network modems.
All fixed when I finally found the right Radio and flashed it on the phones and unlocked and flashed the latest modem firmware.
My broadband connections are always on and never drop out and my HSDPA signal on my HD2 is through the roof!
To further emphasise the point all the equipment is used (when home based) behind solar glass which is notorious for blocking mobile phone signals.
Land on the best one and you will get incresed battery life as well.
Bottom line is try the latest radios (2.08.50.08_02 in my case) and I think you may be surprised at the results.

I have the same problem with the connection dropping. What I did to make it work was to disable HDSPA and putting GPRS to CHAP instead of PAP, and so far I have no problems at all
Thanks for the reply and tips. I also did the same earlier today, except that I did not change PAP to CHAP :O. I was waiting until tomorrow before I posted any results, but I gotta say so far the connection has been stable just like yours.
I also called HTC's customer service in Denmark and the fellow I spoke to was very helpful but he said he has never heard about such problems. He sent me updated network settings via sms, but it did not fix the problem.
I mean, only some users around the world suffer from this problem, right? So what is it that's wrong with our devices? Is it a production fault? If I exchange my phone for a brand new one maybe I won't be unlucky again? When 3 DK finally told you the problem was unfixable, did they mention other users with the same issue? Did they ever offer to replace your phone?

Erm!
It's your radio!
But, I think I did say that in a previous post.
You had a helpful fellow who sent you updated settings?
And he thought that was going to fix your problem?
That was helpful!
It's your radio!
The technicalities are beyond a customer assistant at the end of a phone. They work from a script.
I'll send you the settings.
Have you done this?
Have you done that ?
Never heard of anyone else with your problem!
It's your radio!
T-mobile uses PAP protocol (at least they do here in the UK) and it's a handshake protocol so changing that won't really do anything to the signal definition.
You have it or you don't.
It's your radio!
There is no "production fault".
You are not "lucky" or "unlucky".
You are in an area where you will suffer from this because of the ???????
THE RADIO!
I think I have made my point.
If it turns out that you don't have a radio issue then please feel free to admonish me.
Until then----------
It's your radio!
well I don't mean to sound rude but do you SERIOUSLY think we haven't tried that? ive tried every possible radio available here and every different rom, so excuse us for trying new things.im glad your not having any troubles yourself because it is really annoying
perhaps you could post us your rom and radio?
I don't suppose you could post us your settings in advanced network?
did you use the connection setup?
thanks for your help
Yes, I was about to mention something similar. I haven't tried combining different ROMS & Radios myself, but I know people like cgrec92 who have with no good results.
And if it is the radio, then every 3 Denmark user like me would be experiencing the same problem, correct? I don't think that's the case. Actually when you read the forums you will find users from different countries with this problem, and they/we are not the only ones with a certain combination of ROM/Radio.
So yes, by disabling HDSPA I finally managed to have a stable data connection (but no 3.5G, obviously). At this point no one seems to know the cause of this issue, but I suppose it's naive to expect a future ROM to solve it, after all it's not a widespread problem. Is HTC even working on it? Are we sure it's not our devices that are faulty?
I honestly have no idea, but I cannot just accept this problem and live with it after all the money I put into this phone. That's why I brought up the possibility of having it exchanged for a brand new one in hopes that it will not have this problem.
Any ideas?

The post by pa49 was to DORMIU.
I'll pm you my t-mobile settings.
And I cant use the connection setup, being an O2 HD2, it only allows selection of O2.

I referred to my radio in my previous post -20.08.50.08_02.
My OS ROM is Leo Lite 3.
Connection setup used and no further settings.
My explanation for this is the fringe nature of the received signal.
The radio its constantly 'hunting' for a signal and the radio software has difficulty in locking on.
BTW OS ROM and settings ready don't affect the efficiency of the radio signal.

I appreciate the help, but he doesn't seem to understand the issue here. It's not that we have low connection, or that we cannot connect to the 3.5G network. The problem is that the phone's data connection will automatically disconnect even when we are in an area with full 3.5G signal. The phone will connect for a while and then, moments later, in the same spot and with full signal, data connection is terminated. So I just can't see how the radio has anything to do with that, especially when there are hundreds of other users out there with the same ROM & Radio as us and in the same network. And yet they do not experience this problem.
Ive have similar issues but it depends where i am it appears that some towers its ok where others its not!

The radio differentiates between all the different levels and types of signal and it depends on how exact it interprets the signal. They are supposedly optimized before release and then re optimized with each newly released version. Network operators then have their own network parameters and again the radio has to accommodate this as well. One radio will never satisfy all these criteria and some of you will be in the wrong place at the wrong time on the wrong network with the least effective radio.
I can assure you that I most certainly do understand the problem and that is why, in my own case, I have resolved it.
