Hi All,
Done a quick search on this and can't find anything relevent, but i apologise if a thread already exists.
Really a question for those in the UK on the t-mobile network. Have any of you attempted to sign up for the orange 2g roaming service yet? I signed up, recieved the confirmation text, replied to it, and received the final confirmation. However, I'm not sure it's working. The signal seems no stronger, and i still drop in my house.
Obviously i'm posting this in the android section because i'm running android myself and am wondering whether anyone in the same boat has managed to get roaming to work. Should the fact that we're on a non-official OS running off the sd card make a difference?
Oh and for completeness, i'm running shubcraft 1.5 rmnet.
Cheers fellas!
I'm quite happily flip flopping between Orange while at work and T-Mobile for everything else...
works like a charm for me though you do have to stick the phone into Airplane mode after selecting the different provider for the data to work ...

Many thanks for the reply Jezwick. So, just for clarity, you're manually selecting each provider as and when required? Because i can do that, i think. When i select orange though, whilst it registers with the network fine, i get a little "R" above the signal bar (any ideas what that means?) And the speed appears to be limited to Edge. Orange have a very strong signal round here, so i figure i should be getting GPRS really.
It's the auto-switching i'm not totally sure is working really. Is there any explicit indicator that it's flipping on it's own? Or do you just observe a generally better 2g signal, rather than say, a very weak 3g one? Round the house, my phone is still trying to make do with 1 or zero bars of 3g. I would have hoped it would flip over to orange more or less all the time under those circumstances. Nothing to stop me manually selecting it i guess though...

The R is indeed for roaming that's the way it works if your not on your 'own' network.. The 'flipped' service will currently only work at GRPS speeds at the moment but should be 3G by the new year
I have noticed mine flipping automatically but only once or twice in the last few weeks but only when I get NO signal from the current service.

Understood - thanks for the info Just done some reading and apparently EDGE is faster than basic GPRS. For some reason, i'd always assumed the reverse. Looks like the best option is just to have it always on orange whilst at home and use wifi for data (which i do anyway to compensate for the poor signal). Cheers!
I got my G2 a couple days ago and I must say this phone is amazing..coming from a g1 I had for 2 years its quite an improvement. The only minor problem I'm experiencing is with the radio signal..most notably in my house..on my G1 I always had signal and internet connection. Now with the G2 I constantly loose connection all through out the house and the only way to get it back is to switch the airplane mode on and off and it picks it up right away, only to go away a few minutes later..I don't seem to have the problem anywhere else.
Was wondering if any of you guys can shed some light on if there is a way for me to figure out why the signal is so random in my house and it was ok with the G1. And why airplane mode seem to fix it for a short while.

did u activate the sim card that came with the phone or still using the old one?
I'm still using the "old" one still but considering I got it 2 months ago I wouldn't think its a big deal unless the sim that comes with the G2 is any different?

I asked because i was told to activate the new sim card to avoid issues likes the ones u seem to be having.
I was told to replace the sim card as well. After doing so there was no change in the reception of the unit. The downside is that the sim card does fine in my Vibrant but does not work at all in My Nexus One. Tried two different new sim cards and each time the Nexus One refuses tacknowledge it while the G2 and Vibrant do. I have found no difference in signal quality or strength with the new sim. The new sim card has a much smaller gold contact area and that area is a slightly different shape,
I went ahead and activated my new sim card to see if maybe it'll fix the problem..ill let you guys know how it goes

Changing the simcards will not work. If I put my simcard in my iPhone 3G or my G1, I'll have 2 or 3 bard with 3G, but with the G2, It switches up all the time, from Edge to 3G or no data at all, with 1 or 2 bars. I also have five other family members that also have T-Mobile phones and their getting about 4-5 bars on their phones. So it's not the sim or a tower issue.
There's cleary a problem with these phones.
This mourning I woke up and found the phone with no service, no bars. I reset it and came back, this afternoon I left the phone on my bed, came back to it, and again no service, it seems the service keeps going out for no reason.
Another is, I live in a big building, when walking in and out the building, my data connection will drop, or sometimes I won't even have any service, and again the only remedy is to restart the phone to get service back, airplane mode won't even fix it.
Yea the new sim hasn't really fixed anything at all..

damn i was about to try that... guess i'll keep waiting... maybe an OTA radio update will help this cause it's really getting annoying.
I don't have a problem with my G2 dropping signal completely, but I have noticed that my 3G is very spotty. It's probably because I was spoiled the the MyTouch Slide's 3G only option.
Yes, I've noticed that the signal isn't quite as good as my G1. It's seems to be about on par, if not slightly below my friend's Vibrant.
But remember, the G1's radio really sucked once upon a time. Radio updates. They will come. Every phone that has OTA updates always gets new radio, in my experience.
I'm on my 3rd G2, mostly for manipulating the purchase price, and have noticed on this 3rd one that the spring is looser than the first two, the phone resets itself and often, and I'll loose data even though it shows I'm connected. This will happen in edge or hspda. I'm taking the phone back tomorrow.
Crappy thing I just put the ZAGG complete invisi shield on it. WIll Zagg comp me another cover you think?
If only Tmobile would activate the UMA calling over wifi. This would be the perfect phone with perfect service.
I am going to call tmobile in the morning and see if I can get any word on the UMA release. If not, the phone may have to go back.
I'm having the same problem, not at my house but at a local ihop that happens to be walking distance from where I'm moving in a week. I tried a reboot, airplane mode, even pulled the sim card and nothing worked. I got signal back once I left, but since it's right by the new place I would like to not have to deal with this.

well ive been searching around and i think ive found something that could help..
if you dial *#*#4636#*#* you will get a little screen of information about your phone, go to phone information, under phone information scroll down until you see select network type, the network should be automatically set to "WCDMA preferred" ive been playing around and i set mine to GSM/CDMA auto (PRL) and since then (about an hour roughly now) i havent lost my signal or connection in the same spot i was loosing it in my house every 10 minutes or so. not sure if this fixed anything but so far so good. definately will let you guys know if it continues to be good or if it doesnt stay consistent.
heres some information also in case you dont know which one would be best for you.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

Having same issue with the signal. Swapped for a new sim but still the same. Sometimes service drops completely and I have to go through the settings menu to search for a signal in order to get some reception

phone came in wcdma preferred stock... I came by that option too but I would much rather suffer with spotty signal [HSPA] over Slow edge speeds...
that said I may turn on GSM only when I'm indoors with little coverage, should save a lot of battery.
is there a setting that forces the G2 to go for the G3 or H setting instead of the edge? I live in an area where my phone can get both and it always goes for the edge signal instead of a weak H signal and the edge is soooo slowww.

*#*#4636#*#* then phone information, then scroll down and change the drop down from auto to wcdma only. Only problem with that is if u go to an area with no 3g, u get no service and have to change it back or go under the settings and wireless to enable 2g connections

Hey there, I enjoy reading this forum but I had little to contribute with as I am an android noob. So unfortunately my first post is a question forced by the fact that something is wrong with my DHD Thank you in advance for your advices!
The problem is - when in areas with low 3G coverage the phone keeps on searching for 3G for too long instant of seamlessly switching to 2G, which often has full signal bars. This way the phone acts as if there was no signal and sends incoming calls to the voicemail even though all it has to do is to switch to 2G as soon as 3G gets too weak.
My previous phones had no problem with this. In my city the 3G quality varies from area to area but the 2G coverage is perfect almost everywhere. So I used to be sure that my phone never really disconnects from the network, it only might have dropped the 3G signal in favor of 2G while keeping the calls and everything.
I know I can disable the 3G and stick to 2G and EDGE but this way using full data capabilities of the phone turns into pain instead of pleasure.
Just to make sure and to show I did my homework, this is NOT:
- the death grip case
- a network related problem /I suppose.../
- a problem with data connection /I have never run into any problems with this/
My questions are:
- is anyone of you experiencing this?
- is there a way to force the phone to hand over the connection from 3G to 2G quicker without "blind spots"?
- does any custom ROM improve this? /I am running the latest stock HTC DHD android 2.2 with Sense/
- is there any hint that android 2.3 gingerbread should fix this issue?
Thank you, hope to find a piece of good advice here!
I`ve found this service menu and I switched the preffered network from WCDMA preferred to GSM AUTO PRL. will see if it helps.
I havent noticed any more problems since I did the switch. I think it helped. I cannot be 100% sure but I think it did the thing for me. I forgot to mention that I also switched networks mode from Auto to European but I think this has nothing to do with the issue.
fortuneman had my answer. To access the service menu on the soft phone keypad enter *#*#4636#*#* and its under Phone Information.
Switching from 2g to 3g works seamlessly. But the other way around doesn't work that well. Nothing to do with the phone. Just the net tech that has its flaws. If your in a call and switch to 2g, the call will most certainly be disconnected.

Anyone noticed on gs2 it switches to 3g until H is needed for data. If I'm in an H area it doesn't stay in that mode all the time.
I know H drains battery more so on the gs1 could the same functioning be transported. In theory giving better battery life?

Same for my sgs2 (I am on orange)
At first I just thought signal was not so great in area I live but then the H pops back when I start downloading and using net, I can see why they have made it this way but I am also a little unsure as to how much this helps, the swapping from 3g to h then 3g to h and so on and if this itself does not either slow our use as we wait for it to swap back to h and if saves energy or uses more? (like in a car changing gears more often uses more fuel)

Yes. There are quite a few people with 3G and HSDPA issues:
http://forum.xda-developers.com/showthread.php?t=1074396
http://forum.xda-developers.com/showthread.php?t=1073958
Yours may not be an actual problem if your getting decent speeds but mine is failing to stay on HSDPA when downloading and getting very poor results (64kbps) in an area which I normally get around 2000kbps.
I've spoken to Samsung but they have yet to respond with a resolution.
Dont know if its an issue for me as it swaps back to 3g once its got all it needs (page loaded) its stays 3g until i click on next page or it needs it then jumps to H again.

Same here - no problem with speeds or whatever, but once it's finished it changes back to 3g. I'm on vodafone.
I'm in Australia with H+ and it will only switch to that when I'm actively downloading something, could be a battery saving feature?

Ahh see my sgs (i9000)didn't. It was always on H or 3g depending on signal.

I noticed this too but I have yet to properly test it to see if that's actually what it's doing....
my nexus one also stays on H always and never switches back and forth for the data transfer.
however i thin kit is network dependent sometimes, because when i traveled to a different city a few weeks ago suddenly it would switch between 3G and H anytime data transferred. as soon as i drove about 15 minutes north out of that city, it returned to constant H and back to normal.
so i dont know exactly how or why this is caused. i'd prefer to jsut stay on H and not change back and forth.
Depending on Carrier actively terminating HSPA when data transfer finished?
Is the same on my HD 2 .

I chose Orange via CPW. I received my SGS 2 yesterday. Such a stunning phone but I'm returning it as I can't connect via HSPDA. My two O2 Galaxy S's sitting on same desk connect at H without issue. If I take out the Orange contract SIM and replace it with one of my O2, the SGS 2 connects at HSPDA immediately. Definitely an Orange issue.
Hopefully I can take advantage of CPW policy to find a network that works for me. Would be great if I could keep the handset (put protective screen on it and time spent customising handset) and pop in another SIM.
Anyone tried changing the preferred network type? On my Nexus One the default (which I never changed) was WCDMA preferred, on the GSII it's GSM/CDMA auto (PRL). A brief bit of research online suggests that this does affect how the phone switches between available network types.

thank you for useful info
I get this issue when I have GSM/WCDMA (Auto mode) selected.
Speed tests are rather slow even when it switches to H. When I select WCDMA only I get great speeds (3Mb+). Still switches between 3G and H though.
My issue is that I've never been able to connect to H+ in central London on Three. Not sure if it's my phone or the network.
This is actually how the umts/hspa technology works. HSPA as a technology is only for data, so it's used only then. Carriers drops the connection back to umts if data is not used.
This is also related to the FastDormancy bug discussed here. So it might also relate to why this phone does it so often or fast.
I've tested two usb-modems and another phone in my location and they all do exactly the same thing what galaxy s ii.
My network provider always drops the connection to 3G if data is not used, it can't be forced. A way around it is to keep a small download going.
E.g. if I use a usb-modem on my laptop and want to keep it in HSPA (for some reason...), I just put wget with 1kt/s download in the background.
The networks capacity is not limitless, so older technologies is used instead.
Hope this clarifies things.

My problem is not that it goes back to 3G but it's dropping back every few seconds, even whilst downloading. It doesn't happen on my other Android handsets on the same network. So it is a problem.

I'm in U.S. on AT&T, with an HTC Inspire "4G" and SGS2. The Inspire stays on H+ at all times, idle or active. The SGS2 does bump up to H+ on demand it seems. BTW, The SGS Tools app with the dialer codes still works fine on this device. I've been messing with network bands since I got the phone.
Just to add. I'm using the same vodafone sim card from my old sgs and it always stayed on H unless signal was 3g only area.

It didn't do it on my SGS with same sim card/network. Speed results between the two are very similar. Only network performance issues experienced were when immediately after i swapped out the sim card from captivate to SGSII and shortly after i switched my data plan from smartphone plan to medianet
Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?
maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.
When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Okay, I guess it's the 2G mode.

How can I fix this and get back to using 3G?
Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available
Sent from my GT-i9100 equipped with Grenade Launcher and Remote Explosives
Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!
:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location
I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".
I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).
If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.
