[q] vibrant gsm nework issue... Pls help!!! - Vibrant Q&A, Help & Troubleshooting

TSL/G/0199/017
Good Day All,
Here is a problem.
I have a Samsung Vibrant Galaxy S SGH-T959 from T-Mobile USA and on ECLAIR and I was having issues detecting network in Nigeria. I tried several updates but still got no improvement. However had slight changes with the detecting of Nigerian networks like MTN, GLO & ZAIN after a successful upgrade to firmware version 2.2 (FROYO. UVKBS) but still unable to detect my network ETISALAT. My current Baseband version is (T959UVKB5). Even with the manual network search I still can't detect GSM network.
The phone is unable to detect GSM networks.
Please help out if u have a solution.
Thanks

Since you're not having this problem with other Nigerian providers you should really be asking this to your current provider, they're the ones most capable of helping you out on this. It's clearly not a hardware nor a software issue.

Have you tried changing your access point name info?
Go to settings-wireless and networks-mobile networks-access point names. Click the file and input this info http://www.google.com/support/forum/p/android/thread?tid=29c82c52aa079431&hl=en. I have to do this for my wifes vibrant on simple mobile here in the US.

[Q] Atrix problem "network with limited service found"

Hi,
I have strange problem with Atrix, it's registering to network then it is showing "network with limited service found. do you want to initiate a network search".
Mobile network is connected, I have good reception, I can use Internet access over that network, however cant make/receive.
Stock firmware, no changes.
Any information much appreciated.
Rob
That's odd. I guess T-Mobile is compatible with the atrix in the UK?
If your phone is completely stock, maybe Moto or your carrier could help you with it if nobody on here can. I'm not an expert, but if you just got this phone, then if you wouldn't mind doing a factory reset, that may squash any problem. Another thing that it may be doing if it's a new phone is try to update itself to a newer build? When you go to wireless and networks and look at the list of APNs, what is listed and what is it currently connected to?
Hi
Thank you so much for your replay. Unfortunetely i've done all those.
I think I can do much more than give headaset back to the shop as not working.
Regards,
Rob
Ps. Funny enough I'm sending this from Atrix on 3G connection but still cant make thw call.

Mystery solved, I have bought a "blocked" phone.
I called Orange UK to ask about status of that IMEI (as that was Orange phone), and very nice lady told me that phone is blacklisted with "lost or stolen" description.
So next time when your toy cant login to GSM network but working fine on 3G/GPRS please first check is phone is not blacklisted.
Case closed.

Hi all,
First time poster, long time follower!!
I'm hoping someone can help me here because i have a real headache with my galaxy s2.
When i got it at Christmas everything was perfect. But two weeks later i suddenly lost my 3g. Phone works fine on 2g (except for the slow speed), but i contacted my carrier 3Ireland and they said everything is fine on their end. My APN is perfect, i've tried toggling airplane mode, entering codes, data package checks. You name it and i've tried it.
When i force my phone to select 3g it looses all signal and i have to restart my phone and quickly go back into settings to choose 2g or i will loose signal again.
This is the following on my phone.
Android version 2.3.5
Baseband version I9100XXKI4
Kernel Version [email protected] #2
Build number GINGERBREAD.XWKI8
I've being reading about modem/radios lately, is that just the baseband? Could that be my problem. I'm a noob at this kinda thing.I just want my 3g to come back.
All help is greatly appreciated. Look forward to hearing from you all.
Thanks.

I having the identical issue on 3Ireland network. No 3G connection at all, only 2g. Changing radio version does not help either.
hallo dare, have you sorted this problem?

It would be interesting to know your SGS2 is white version as well as mine.
I have to say that I have another SGS2 but old black version which is perfectly functional on the same 3 network. After playing a very long times with both phones settings, I have a feeling that the core of the problem lies in the "APN type" setting. Changing it's content affects how it connects to network. I have no deep understanding of what is happening behind the scene while changing this option, but there is a possibility that the portion of file system responsible for it somehow been damaged.
It would be great if the developers could tell us if this part of the Android file system is changed while flashing different firmware/radio, or it is persistent?

Dial *#*#4636#*#*, go to phone information and see the settings for the radio. It should be at the bottom. Google the settings for the GSM, WCDMA. Mine is currently 'GSM auto PRL'. 'WCDMA Preferred'is also a better option for 3G network.

Thank you. I fiddled with GSM, WCDMA settings as you said, but no luck.
What is even more interesting is if the network mode is set to "WCDMA only", then I'm not even able to register on 3 network. After an attempt to manually connect to 3 via "Network Operators" menu, it says "Unable to connect. Try later".
Also after connecting via WCDMA, and then reverting back to GSM, the GSM dies as well. The only solution is to restart the phone.
If it is a software bug, then I do not understand why this problem did not go away after flashing different Rom with radio.

exactly the same for me also, by the way i've a black version
Same problem
Same problem for me in Spain...
WTF happens with this Galaxy S2.First USB voltage problem and now no 3G/HSPA connection.
Any solution, plz??
Samsung: never again
guys....carriers can't sell a device that is advertised as a 3g capable phone. Call them and spit "misleading advertising" mixing "give me a phone that I can actually use" words. You could also add "Release me from my contract, I'm moving to other 3g WORKING carrier".
They'll just freak out.

T-Mobile USA?
If yes, you're probably in a market that they have not yet re-farmed the 1900mhz frequency for HSPA+ yet. The i9100 doesn't get 1700mhz, and the majority of T-Mobile USA's network uses the AWS band, which requires both 1700 and 2100mhz to work for 3g/"4g".

Accidentally USA Band pl Help

Hello I am from india I have Motorola atrix 4g.
My first problem was that it was not having data on off setting under Mobile network. Which in other Mobil I have. In case if no network connection I used to dial *#*#4636#*#* to see the data condition whether it is on or off .
Once I accidentally opened select radio and selected USA Band. Now I lost all network.what to do please I have searched the forum but not understand the answers or I fear it is not for my Mobile software version. I can not decide which solutions to use.
Important notes
I don't know whether it's at&t or other.

Hi jatinmend,
I can't help with your problem, but I do not believe your phone is an AT&T phone. I just purchased a replacement for my AT&T Atrix that broke, from Newegg here in the USA and it has the same build number. The other data in the about phone area indicates it as being an Asian region phone. Under system Version it says 45.31.0MB860.AsiaRetail.en.03

[Q] Xperia Z2 US T-Mobile LTE Connection Issue

I've had my Z2 for over a month now but I've been unable to connect to T-Mobile's LTE network here in the US.
I know for a fact there's LTE in my area (I live in Seattle). Other phones have had no problem connecting to LTE.
After talking with T-Mobile's tech support I should have the correct APN settings. They also refreshed my phone on
their network. It helped somewhat. Before they refreshed, I couldn't detect the LTE network. Now I can detect it
but can't connect.
If anyone can give me some advice as to how to get things up and running that would be most helpful.
I've attached some screenshots that may help in diagnosing the problem.
I'm on T-Mobile in Los Angeles, and those are my settings... The only difference I have is the APN protocol is set to IPv6. Not sure if that makes a difference. Otherwise, we have the same exact settings and my LTE works fine.
Call TMo. Sometimes they have to reprovision your phone on the backend. I had that ptoblem with my Z1 but not with Z2. My APN type is blank. The settings can be found at TMo site. If you cannot find them, call TMo and they wipl email that to you.

Thanks for the suggestions.
I changed to IPv6, IPv4/6; I still get H+ but I dont get LTE.
I did call them, I guess what I meant by refresh was "reprovision". When I first got the Z2 I couldn't even detect LTE with network search.
But after talking with them; I was able to see the network. But for whatever reasons I cannot connect to it.

Might be a stupid question, but are you using an LTE-compatible SIM card?
haha, no that's actually a good question. I wasn't before but I went to t-mobile and got a new lte compatible one. but nothing's changed. i'm thinking maybe there's something wrong with the sim card.
Mine hasn't said "LTE" since I updated to .402 FW. It says 4G now instead, does yours show neither LTE or 4G? I get H+ in some areass, so I know there's a difference between the symbols (even if Tmo likes to think they are both 4G).
Try flash .438 ftf file via flashtool
To see can solve it.
Sent from my D6503 using XDA Free mobile app
I flashed unbranded. 402 ftf from Germany when I first got my device. Then I deleted the factory t-mobile apn that it downloaded and used these settings. They always work for me with unbranded international devices!
2219
The icon im getting is 3G/H+
Singtel .438 didn't work; same problem;
It might be an issue with my baseband.
I have
8974-AAAAANPZQ-00005-09
I'll try flashing germany .402 now.
