Hello.
I got a strange signal issue with my Universal. The phone will only connect to the cellphone network every now and then. GSM and UMTS alike.
I've tried a few different SIMs, most of them won't change anything. Had one that worked fine (not my sim, and costly plan).
What happened was the following: Phone was working for forever, when the provider updated the sim. The phone wanted to reboot, so I did, and the problem started. I contacted a the service provider, and they had no clue, so I contacted HTCs workshop here. They told me that they had indeed seen this before, and that they had solved it by "ordering 3G compatible SIMs", so I did. Nothing changed.
After this, I remembered that I had another sim (same provider), that was not updated yet. I put that sim into the phone, and once again the phone was connected, and working fine for 2 days, when the update came again. After restart, same issue.
I've tried updating the radio and so on, but nothing changed.
Now, I haven't managed to figure out any more, and now wonder if anybody here has experienced anything similar or know anything about it.
I kind of doubt that it's the hardware, as the non-udated sim worked, but the updated ones don't. That is also supported by that sim that actually worked. (I asked what was special about that sim, nothing).
Any tips?
I recently bought a used Jasjar, and I have similar trouble. I think it's because the GSM frequency band used by the Jasjar (I think it's 850MHz/1900MHz) is not as prevalent here in the US.. I assume there are fewer towers in my area that support this frequency band. The Jasjar was intended for non-US markets, I think. As I drive around town, there are certain spots where I lose my signal completely.... which never happened with my previous phone (an HTC Wizard, which uses a different, "more prevalent in America" GSM frequency band).
The new SIM's you are using, probably point your phone to a newer network (a different set of cell towers/radios), which doesn't support these frequencies as well.
That is correct, Universal will only work on 3G in Europe or Asia.
For America only in GSM bands
Europe
I forgot to actually mention that I'm in Europe.
Won't give up before I figure this out. Love the phone.

I'm no cell phone expert, but the SIM is just a memory chip with info on it. It has nothing to do with the signal quality or radio in your phone.
Inside the SIM's memory is a serial # and some info about which networks it can connect to.
So, I am guessing your new SIM's are pointing your phone to a different network, that does not use the same GSM frequencies the Jasjar uses. Or, perhaps your provider has swapped out the radios in your nearby cell towers for "newer" radios that don't support the Jasjar's frequencies. Does your phone work in other parts of town?

Yeah, I was thinking the same when this happened, but no one changed any equipment here. Both providers run with the same equipment, and is the same as when it worked. Got that confirmed
same problem to me!
YEah! I have the answer, Its about the channels of signal transmission, The Unis are old devices, need a high channel spectrum in the GSM signal, the new devices are more faster DSP´s in their CPUs and the spectrum of the GSM signal service scan load more devices with less channel in use (more cheaper and more services) The UNI is an old device now you may need to accept that need more channels to work in a full capacity of signal, sorry!! UNI´s and other old devices soon gonna useless

I live in southern africa where its still going to be some time before the G1 is launched.
It would be possible for me to order the US G1 from ebay but I am concerned about the network band because firstly I want to know that the phone will at least work on the regular 2G network (1800 in my country) for the usual phone calls and then of course I want to be able use 3G for Internet access. I don't know the 3G frequency in my country but the service has been available for over a year already.
Is it a software restriction which can be resolved by updating the firmware at a later stage or is there actually different hardware for the model being released in the US and those being released in other countries like the UK?
Thanks!
Take a look here to find the UMTS frequency that your carrier uses (of course, call to double check):
http://en.wikipedia.org/wiki/List_of_Deployed_UMTS_networks
It hasn't exactly been confirmed yet, but the G1 is supposed to support both 1700+2100 (UMTS IV) and 2100 (UMTS I) networks. Since African carriers are all using 2100, you should have no problems getting a 3G signal without having to worry about hardware/software compatability. You should also confirm that your carrier will provide the approrpiate connection settings in case you need to set it up manually.
The G1 also comes with quad-band GSM/EDGE, so you will certainly be able to receive 2G signals.
However, keep in mind that the first batch of G1s will be locked to T-mobile. You will need to make sure that you get a carrier-unlocked device in order to use your carrier's SIM.

Thanks, that makes me feel more comfortable with ordering a G1 from the US.
I was just concerned because I read somewhere that the US version does not work in AUS so there obviously are problems in some countries with the bands. The UK version will apparently work in Aus.
Again, I want to emphasize that you need to make sure you have an unlocked version. When you first turn on the phone, you are required to log into gmail (or create a new account) over a 2G/3G network. If you are unable to login (because the phone has not been unlocked to work on your carrier's 2G/3G), you will not be able to use the G1 for anything other than emergency calls. You won't even be able to enable WiFi to handle the login.
http://androidcentral.com/g1-wont-work-without-a-data-plan-period/
If at all possible, I would advise waiting at least until some other folks have tried bringing the G1 to other networks so that you know what exactly you will have to do to get one working on your carrier.
Thanks again, I will definitely ensure that I do not purchase a network locked G1.
So when I leave all the band settings to auto on the phone, it immediately connects to AT&T's 3G network and shows the "H" in the title bar it worked for a little while then calls stopped coming through, after a hard reset it works again with calls for a few hours, then it begins to fail.
If I switch the bands to GSM and manually select the frequencies (850 + 1900, according to wm) then it connects to the EDGE network, and I can make and receive calls as I please, no problems, except for the crappy network speed.
So someone help me out here please, is the phone defective, or is it not working as it should because of the lack of the 850 band? I know that AT&T works on either or but this problem has me stumped.
Other than this rather huge problem (phone that cant make calls), I absolutely love the Xperia and would hate to return and wait for another.
did you try to use the connection wizard to let the phone config itself?
after I put my iphone sim in it shows the H/3G icon on anf off all the time, while I can receive call I was unable to go online.... after someone suggested me to call att to update the imei on my account to the x1, I found that I still have to go to connection and change the setting myself b4 it can go online. you will have to remove the user name and pw in media net setting and uncheck the proxy server.
I guess my case is a little different than yours but I guess you can give it a try... good luck =)
Thanks, I actually haven't tried that since i figured it would be the same as what happens when you turn the phone on for the first time, when it autoconfigs.
if it say it detect a new sim and ask if you want to do the auto config then I guess its the same... but again I did need to change some settings inside the network config to make it work too... so I am guessing the "auto config" has some flaw in it
No problem with my X1i when I venture in a1900mhz area close to my home. I live in a small town in Ca. only 850mhz here. But in the larger Metro area around me... No Problems with calls or hspeed data access...
Stuart
Thanks for the replies, It looks like the Configuration wizard in the settings menu did the trick. It do something else that the autoconfig doesnt. The phone seems to work now just fine, although it doesnt hang on to the signal as well as my old k790a. The office I work in is an ATT dead zone and I could make calls using the K790a with only one bar, with the Xperia it either doesnt go through or drops the call.
Again this is better as it works now, just not as well as my old phone.
Also, scl_electronics, so you are saying the X1i has both 850 and 1900mhz bands? I had a feeling mine did too, but I thought it was put to rest that that wasnt the case with the X1i....
Sorry Aaron J,
i should have been more specific!! Where I live, 3G is only on 850mhz band so I don't get access..Just The edge network. When I venture about 10 mile away toward the major Metro areas..The 1900mhz band are used. So the H is displayed, but I don't have those access problems for calls or data!!
But i am waiting to see if they can crack the rom for 850mhz-3G access!!

Oh ok thats kind of makes, sense although I thought the X1i didnt have an 850 band at all, so what frequency does it work off then?
Anyways, back to my problem....I spoke too soon, it dont work on 3G switched to EDGE. I might just try getting a new sim card, mine is a Cingular one from 2005, that has been in at least 4 different phones now including the X1i.

Well out here in Ca... 850mhz gsm/edge is used ..So I quad band gsm phone is handy!!!
Stuart
Yes it is! My little problem is a little confusing though as one thing I just realized that I didnt say before is that the phone has no problem connecting to the 3G network using HSDPA. I get full bars with the H icon pretty much everywhere in my area and my data speeds are very good. So I can surf the net, download programs, watch high quality youtube videos using the app in touchflo and even send and receive texts just fine.....just no calls when on 3G. I'm hoping its just setting somewhere and not a faulty device.
I live in Raleigh NC by the way so maybe it could be a faulty tower?
Well when venture into Stockton Ca. my phone switches to 3G-HSDPA:1900MHZ Without a connection hitch....
Have you tried a soft reset......
But when all else fails Hard Reset to the Rescue!!!
Btw... in several of my ppc-wm units when restoring to OEM setting(hard reset) there has been many time the process had a problem. So something would be screwed up!! So when You don't succeed, try another hard reset!!
Good luck,
Stuart
hey i was wonder if your problem is HSDPA/HSUPA being on, i have at&t also and it worked for the first few weeks fine with it being on then all of a sudden it stopped and couldn't connect to the internet, before i had the H/Edge showing up and also my email never updated when it was set to do it every 15minutes. Now that i disable the HSDPA/HSUPA i see 3G/Edge and email update all the time on the X1i. Just wonder if that might fix it, I'm all kinda still new to all this but i had my X1i for 2 1/2 weeks now.
Hello thanks for all the suggestions, Experiaenjoy, no I haven't tried mainly because I can connect to the data network just fine and get awesome speeds with full bars pretty much everywhere, all of my data related activities and programs work just fine (aka murder my battery life ). I just cant make calls while on 3G.
I talked to a coworker today who used to be a regional manager at AT&T hee said that he saw many cases of people who were having problems where it was due to the SIM card. He said they all had the older orange Cingular card and that an update to the new blue AT&T card solved all problems. So right now I'm trying to see if I can get mine updated (I do have an older Cingular SIM). Once I get that, I will do a hard reset (3rd one also done about 20 soft resets since I 've had it-I've installed a bunch of programs and tweaks) and skip the auto config and go straight to the connection wizard.
I just bought an hd from a store in canada but used (demo)

cannot seem to register on the gsm network.
fido gsm is 850-1900.
I know g3 wont work but gsm should and is not.
try changing the radio, check the wiki, might end up being a bit of trial & error. You could also try going back to a stock rom first.
thanks i may try the radio.
I think my rom is a stock one?
No one here using fido?
I was able to register onto the network when hard reseting with the sim in the phone...
took a long time to get a signal...
signal was there, gprs icon was on... but wsn't able to receive calls or make calls.
When calling my cell, i got the answering system.
how to be sure it is not locked?
Still cannot make or receive calls
flashed with RUU_BlackStone_HKCSL_WWE_1[1].19.831.0_Radio_52.49a.25.26_1.09.25.14_Ship.exe. Still same radio as before.
now registers fast in network
gets signal and Edge icons but cannot make or receive calls - no line...
could it be it is not unlocked?
They told me it was...
how to be sure?
changed the sim card to a newer one made after 3G introduction and it now works.

But only works when the network icon is G. It doesn't when icon is E.
Here in Canada the phone's 3G capabilities are not used.
When i am somewhere where the network icon is E, i got a signal icon but no line. I cannot make or receive calls
Anyone has seen this.
Phone band and network are in Automatic... if i try to asiggn a band and network manually...same problem.
it honestly sounds to me like something is damaged with the phone, i think you should see if there is an HTC partner in Canada, and check to see if maybe the device is under warranty and can be repaired.
Im in Canada with rogers and have no problem making or receiving calls with my hd. 3G dont seem to work though
well it seems it is a known issue
http://forum.xda-developers.com/showthread.php?t=476139&highlight=edge+gprs+drop
mine has also a SN beginning with HT845 as many faulty devices have.
My problems is i have olinex 1.14 on it
I have a Touch HD too and works fine with Fido here in Canada.
I used the factory rom for about a week then used the custom rom.
have tried several roms and they all worked on my HD with the fido network.
the only thing is i have the roaming icon on all the time, but luckily i dont get charged roaming once i'm in my local area.
Dont know why you are having problems with yours, but like someone said i'm also guessing there may be something wroong with your handset.
try taking it to a repair shop (HTC authorized at least) and see what they also say.
best of luck
HTC Touch HD with Fido
I have also bought touch HD and having same issue, I can dial and recieve calls while I am outside but when I am any where inside I can not recieve or call any one from HD, I think touch hd that I have has 900 frequency that is why I am having issue, Fido and Rogers works good on 850 frequency. Does any one know how can I solve this problem
As I said before I have touch HD with rogers network. I have no problem recieving or making calls even indoors. I bought mine at pacific mall a year ago
Only HTC Touch HD T8285 will work on Fido/Rogers/Bell/Telus 3G network.
I think you have T8282 and this is the reason that you cannot get 3G or H icon on the top bar.
I have T8285 and it works fine on Fido 3G network It show 3G and H on the top bar.
no matter you do (like flashing radio or rom) it will not chnage the UMTS signal. It is hardware related.
I remember people talking about this on the G1 forums and people were thinking this was a bug in the Android software. I do not know if anyone has provided the answer to this already, but I figured I would share what I have found. (I also posted this in the G1 section)
Turns out that tmobile and at&t have dropped their roaming agreement in several areas. The "not allowed on this network" message is due to the phone trying to connect to these towers. Even when selecting "select auto" or selecting a weak tmobile tower, because it fails connecting to the weak tower and then will try to connect to the stronger tower (att) but is not allowed.
This whole thing sucks though, because I have a metal roof that kills my tmobile signal, but I am able to get a weak att signal inside.
negatory
I believe you're wrong there about signal strength.
I've had two seperate g1's that displayed this error when inserting a TMO and/or ATT sim. The phones were both unlocked, and sitting with 2 feet of a TMO g1 with 4 bars of 3G signal.
After updating the radios to most current and calling TMO to question someone withe sense, I was upgraded through 2 levels of customer support. The last fella I talked to apparently knew things, but couldn't say much - you get the idea. He did reset my connection (or said he did) and I watched as service for all three phones on my account died (connectivity) and then gained signal again. All while on the phone with him.
Afterwards, he suggested I clear all caches, facotory reset, etc.
Low and behold, both phones worked with 3G (TMO) and EDGE (ATT) just fine afterwards. Now, was it something HE did exclusively, or a combination of his 'reset' (whatever it was) AND my factory wipe of the phones ? Got me.
I WILL BET YOU A COKE IT HAS SOMETHING TO DO WITH UPGRADING THE RADIO TO CURRENT -AND- WIPING. If i'm wrong, i'll paypal you coke money... but I think I'm right.
If a tmo person in the know, -not a speculator-, would like to grace us, that would be cool.
This has worked for a total of three "Your SIM card does not allow connection to this network" type error'd phones. All of which were unlocked, rooted, and running cyanogenmod latest.
2 cents.
I contacted Google support about this. Apparently if T-Mobile has property rights to the area where you're connecting you are only allowed to connect to T-Mobile's network no matter how poor or lack of signal there is.
Yeah, I tested this myself, tried to connect to the only tower available (an att) and was not allowed. I know you have the roaming issue is you ever see "emergency calling only" in the service bar. Means it has a signal but is not allowed to roam on that signal. I have a good signal outside and in parts of the house, just not where I am the most. There might be a bug where it gets stuck trying to connect to the wrong towers, but the source of the issue lies in the lack of access to att towers in many areas.
Hi, My name is javier, I have bought one nexus 4 8Gb orange phone, but it is sim-unlocked so I can use my MVNO ( mobile virtual operator network) But I am unable to use 3G or WCDMA band in spain.
I Know here are some problems about MVNO and 4.3 and 4.4 and 4.4.2 Android versions, but my problem is not this one. On a Vodafone SIM Card, I am unable to get internet also on this unit. The rest of the phone works flawessly, but 3G does not. I am starting to think that GSM chip is broken. But Hey 2G Networks works well no signal lost, perfectly clear voice on dialing, and constant 20kb internet data speed. No matter is an MVNO or a real operator like Vodafone.
Searching the net, i came over this:
Nexus 4 Suffering from 3G and 4.· Upgrade
And for all of you that are not going to take a deep read, let me tell, that they say there is an error on 4.3 and newer Android framework and Radio Baseband version. So people get unconsistent 3G connection. Well mine is really consistent. No conection at all never. So I think this is not my problem, although I have tried a bunch of roms even all google ones, all basebands and a couple of sims from diferent company.
Anyway, a quick fix is quoted here: Quick 3G Fix But I do not understand what is this or what I am supposed to do with that. Can someone help me with this?
And, after that, I start to look at something more, like Sim Unlocking is snot well done and 3g Band is still locked. Havent tried it with Orange sim as I do not have any. Is there any secret menu where network locks are shown?
And moreover, How can I trace what is happening to my chip? If someone has made hybrid basebands to unlock 4G, there has to be a way to track what is happening to radio basebands while they are working...and perhaps, I can gather some good info to work with...
One more thing on *#*#4636#*#* menu, I can force WCDMA or GSM or the rest options, If I use Force WCDMA, I get signal lost for ever, If only GSM or WCDMA Preferred, it has signal but only gprs internet conection. This is with ONO (MVNO). But with Vodafone, I get HSPA Conection but no internet at all.
Really annoyed with this, hope someone is able to help me with this.
Thanks to all in advance.
Nobody? well i will try to find out myself.
Anyway I have started to know something about android tracking with logcat, and would like to know if there is any way to check all the traces of the modem to check if the chip is faulty or is a driver issue and i have to learn to modify it myself. Thanks.
