[Q] Unable to register on 3G network

First of all, my i9103 turned into brick last month
Somehow I get into recovery mode,flash the stock rom 2.3.6 and wipe all the data
Since then, three-UK SIM card (which only works with 3G) isn't working anymore...
After rebooting for a number of times,I did get it working and make a call ONCE but it doesn't work after that
I sent an email to Samsung and they mentioned : Please be advised that the issue reported with the handset indicates that it may need a software reset, or re-flashing of the firmware, in order for it to operate normally again.
1. Is there anyway to make sure the hardware is working?
2. Should I just try re-flashing the stock rom by myself?
Thanks!

try flashing stock xwla4 rom, in that rom have only 3g network and also its a official 3 branded rom, it should work.

I flashed the Hong Kong version stock rom, and it should be same as it's original one.
Suppose I won't need to do the re-partition thing, hence the data inside won't be affected even if I flash another rom?
Do you think it is a software problem?

Hk rom also works with 3g so now after flashing u should be not facing any prob with 3g network, if u see any prob try wiping cache and dalvik cache. (Hk rom and austria rom both r based on 2.3.6 but there are some changes in these two fws, but it should work fine with any network)
while flashing on odin, DO NO CHECK RE-PATTITION.
flashing a rom doesnt wipes ur data and apps unless u wipe data from cwm or other way.

What does wipe cache actually do?
I wiped all data but not cache last month to fix my bricked phone

the problem of unable to connect to 3G network.
Most likely to be a software problem?

Cant tell surely that its a software prob, if after flashing a stock rom and u still face prob in getting 3g network than could be hardware issue to.
Have u tried flashing stock xwla4?

When you flash make sure, to factory/user data wipe, wipe cache, wipe dalvik. To escape the bootloop, just boot into recovery and wipe, wipe, wipe and reflash. If the problems persist, then go look in the rebelrom forum for more help. For the data problems, it may be that there is no apn. So look up the T-mobile apn and enter them.

Oh, sorry. I saw exhibit ii since it is the U.S. version and immediately thought of T-Mobile. So you have the Galaxy W, the international version. Regardless your carrier should have specific apn settings, so make sure they are there.

can you call and text or whatever? You have no mobile connection whatsoever?
It might not be detecting your sim card

Hmmm, that usually occurs when you didn't wipe properly. Have you reflashed the ROM and made sure you wiped everything through CWM recovery?
I would also try to just remove the card and put it back an see if that works.

Already done all that.. but still nothing change.. there is also the boot problem that happens.. everytime my phone gets on stand by mode it will boot by itself.. and this happens continiuosly

That is weird, it's like your phone is completely rejected the ROM. I suggested posting your problems directly to the rebelrom forum, since I can't help you much anymore
Good luck with the phone.

Yeah.. that's why i'm frustrated with this problem.. i will post on the original rebelforum
Thank you for your advice by the way

No Service with Valid SIM

Got my Nexus 5 on Friday, put my SIM in it and everything worked like a charm. Went through the weekend happy with how good everything was.
Yesterday, I was getting poor signal (connection errors when on LTE). So I decided to try a reboot. I did that and the phone came back with no service. I checked the APN, no issues. I swapped my SIM into my old phone, LTE working fine. I called my phone company (Rogers) and they checked the SIM, reset the network and I reset the phone. No Service (no anything).
I called Google support and their systems were down, so they recommended a Factory Data Reset. I did that - twice, still no service.
Any ideas? I'm guessing I'll have to send this phone in for replacement.

Is the SIM a cut-down SIM?

Nope. My wife's SIM also didn't work. Odd that everything worked fine at first.

Dial *#*#4636#*#* and select phone -> change the drop down box to LTE only and see if data works. Make sure to change to back to something relevant if you want voice/text afterwards (like WCDMA preferred). Sounds like its not set to use LTE anymore.

It's not just LTE, it's all service including basic phone calls. Already shipped back to Google.

go to your carrier and get a new sim card , the one you have has become defective. Your carrier should not charge you anything for a new sim card , if they do maybe 5-10 $

Are you on a 3G only plan? The way many carriers (most of them outside the US, known problem on some carriers in Japan, France and the UK) are provisioning their SIMs, if there is an LTE network on the carrier and the SIM is provisioned as a 3G-only plan, a Nexus 5 will not register to the network at all. There is no workaround to this at present other than to change your plan to something that is LTE enabled.

Rebooted my phone tonight, when it was up again no service. It only says "Searching for Service" I already tested several SIMs and took a look into the sim tray but all pins are still there.
I then relocked the bootloader, unlocked it again and flashed the original images aswell as the radio but nothing works
UPDATE: I managed to get my reception back. I flashed the radio again had no reception, then flashed twrp and wiped data, cache and dalvik cache.

are you stock or rooted?
did you try to flash full stock images then reset the phone?

I have the same problem. After I rooted and flashed to a CM rom my service was gone.
I flashed back to stock with radio/bootloader/system/cache/recovery the whole shabam.
I deleted cache, dalvick and everything else. Nothing helped with getting back my signal.
Is there a new work around for this? I seem to have tried everything that has been posted on XDA. Or am I missing something abvious?
Who can help me?
(ps my sim card works just fine in my gf's phone.)

No mobile data Connection with correct APN

Hello,
I am using my OnePlus One (64GiB) several days already but today i expierenced a total no data connection. It connects to WiFi and uses the Internet with no problems but if it comes to the mobile data connection it can't connect to the Internet while I have full network shown on the upper right corner. I can call and send SMS with no Problems. This Problem appeared just today and i called my service provider and they say that there is no problem with there network availability and I should check my APN settings which I checked and they are correct. Then the customer consultant said it could be my phone.
I inserted a SIM card from another service provider but it also does not connect to the mobile Internet connection.
So it seems to be that there is some faulty settings on my phone or even an defect. How can I fix that?
Thanks in Advance.

That's strange! It seems like a very random glitch then, which often seem to fix themselves as randomly as they occur.
Have you tried rebooting your device, turning off/on data? Also, in Settings>Mobile Network Settings, is your preferred network type set to LTE, or the highest that's there?

If yes and yes, then I'm not sure what could be the problem, considering how it WAS functioning previously. I would just suggest to keep rebooting and fiddling with the Network settings, such as turning off/on data, verifying APN settings, checking Network Operator, making sure SIM is properly inserted, etc.
I wish I knew exactly what was wrong, but I'm not sure.

A factory reset was my last option. Thank you this did fix it.

Did you resolved? I've same problem. Factory reset didn't work for me!

Hi,
I have the same problem. I only had the phone for three weeks now and two days ago internet stopped working in the middle of browsing/watching you tube video. Did not start since even though I've tried several methods (except factory reset, as I want to leave that one as last resort.
Is there any other way than factory reset to fix it ?

Do you all have franco kernel installed?

Need help
I lost the internet connect when I installed CM12 Nightly -> thought it was a bug in the ROM and sorta lived with it.
But when I reverted to 11-S I realized that the internet connection didn't work on that rom either. I've tried everything factory reset - Soft/Hard - reset -> flash other rom's on it. EVERYTHING!!! -> I also tried a couple of different SIM-cards none of them worked, I tried to contact my ISP, they couldn't help me, they said I had all the right settings so it's most likely something with my phone...
I've got no idea on how I can fix it. and would love if anyone could help me sort this problem out -> I don't have any important data on the phone so we can reset it as much as needed...

I did ask One Plus about it, they send me this zip (re-uploaded) http : // www . mediafire . com / download / rmuaie7f8ch5dji / ONEPLUS % 2BONE - StockRecovery - Windows . zip
(can't post links yet) which I then ran to fix the problem. just be aware of that it locks your bootloader again, if you don't want it to lock your bootloader edit the .bat files and delete the line which says "fastboot oem lock" and you should be good to go (worked anyways for me).

Thanks a ton this really was Helpful.. I guess OnePlus One has a glitch 11.1 and now also with 12.1 CM.. Will try Factory Restore and will update.. Same thing happen with my Frnd in India.. who switch between SP's. He had to restore to fix the internet issue.

I have had the same problem on one of my oneplus 2's. One phone works fine. The other phone was working but is not connecting to Internet using data connection. I have checked the settings and they are exactly the same as the other phone which is working fine.

Mobile Data Won't Work After Flashing ROM

After a few problems with my phone, I had to flash the stock ROM again. This was done without a problem and everything works, except for my mobile data. When I press it, it will turn green, but no letter will appear at the top of my screen and the data just wont work.
Anyone know why this could happen?
EDIT: Was a problem with my APN Settings, got it sorted
