[Q] Need Help - Mobile Network Not Available - T-Mobile, Samsung Galaxy SIII

Hi Guys,
I will try to make this as short as possible. I have a T-Mobile Galaxy S3 that was rooted and running the liquid smooth rom and activated on Simple Mobile. It worked great for a little over two weeks, but when my wife went to use the phone this morning it would say "Not registered on network" when she tried to make a call. I thought this may be a carrier issue so I contacted Simple Mobile. I started looking up this issue online and found that many people were in the same boat if they had either lost their IMEI or had a blocked IMEI. I got a little worried since I purchased the phone on Craigslist so I called T-Mobile. They confirmed that the IMEI is clean and can be activated. I decided to unroot the phone and return to stock. I used ODIN to flash firmware build IMM76D.T999UVALEM. Initially it got stuck on the boot screen so I did a factory data wipe and all was okay. I also reset the binary flash counter prior to reloading the stock firmware. When all was said and done the phone booted back up and the device status was back to normal and all seemed right in the world except there was still no voice or data. I thought maybe Simple Mobile just sucks so I went to a T-Mobile store and activated the phone on a prepaid plan with unlimited data. The device powered up and immediately sent a voicemail notification, but did not activate. Under status I have Network: Unknown, Mobile Network Type: Unknown, Service State: Out of Service, My Phone Number: Unknown, ERI Version: Unknown. The IMEI is there and correct.
At this point I have taken this to the edge of my ability and I could really use some advice. I fear that this may be an issue with the device and if so I do not know what recourse I have to get it fixed under warranty since I bought it used. At this point I will try anything and all suggestions/help will be greatly appreciated!

Check your apn settings. Go to settings -> more settings -> mobile networks -> access point names. If you're still on t-mobile then press menu button and select reset to default. If you're on someting else find apn settings for your network and copy them in the right places. Besides that and hardware problem I don't see any other reason, but I'm not an expert on that and I think there are people who will have some ideas on how to fix it.
Good luck

Hi Hajme,
Thanks for the reply. I forgot to mention above, but I did verify the APN settings and everything looked good. The odd thing is that even if the APN was whack, I should still be getting voice. I contacted Samsung and luckily they are going to take it in on a warranty claim, so hopefully they can work it out.

I have the exact same problem but for verizon. If anybody knows a way to fix it please let me know. Thanks.

T-mobile Samsung Galaxy S3 - Searching loop problem for Mobile Network
I am having the same problem this morning! I have unlocked the tmobile sgs3 and i have been using the phone for the past three months using another carrier sim. I searched all the forums and couldn't fine a solution for it! There was no problem with the carrier sim, cos I tried it on my other phones and it worked fine. I have flashed cm10.1 nightly build , aokp , stock ics rom and stock jelly bean, still having the same issue... I have even reseted the binary counter, still no use ! I went into service mode using *#197328640#, found that the carrier name was "unknown". There was no no problem with the antenna, I could still receive other carrier signals . The thing is it does not register , It keeps on going in a search loop! The product was purchased from T-Mobile and is unlocked! What should I do?

easy test
if you still have any old phone in the house, or borrow a phone from a friend/co worker for a few minutes
just to swap the SIM card and try, then you can quickly figure out if it's an issue with the phone or the SIM
SIM unlocking a phone will not cause the network problem, unless the IMEI is black listed
is the phone able to find any network?
also you can use Odin to flash back to factory stock

at least i dont think its blacklisted....i bought it from a guy on craigslis.
but it worked fine for weeks.
why would this cause a problem?
i called tmobile and they didnt say anything,,,,
Go in to network settings and check network operators. If your phone sees T-Mobile/ATT but you cant connect then that means your phone was blacklisted for either being lost or stolen.

when i type 'search now' it doesn't find ANYTHING.
it stays on 'searching' for a while', doesn't select anything
then it comes back showing tmobile and att.
when i select tmobile (or att) it says, "your sim card does not allow a connection to this network"
If the phone was blacklisted, why would tmobile not say anything to me (and why would it only stop working now?)

I would check sim card mine went bad after I took it out of my phone then stuck it in my pocket for a half hour or so when I tried using it it said same thing about connecting to network so I tried my sim in another phone and it didn't work.

change the APN settings. there are a few out there that will work but to keep it simple..
go to:
Settings>Wireless and network>Mobile networks>Access Point Names
press the menu button and go to New APN
for the name put "ATT" and for APN type "phone"
leave everything else blank

nothing worked...tried my wife's sim in my phone, no go.
not a blacklisted phone (according to tmobile).
Since I bought it on craigslist, they wouldn't let me send it back...until I said those three magic words (cancel my account).
They are sending me a replacement---replacement fee is being waved.

I now believe that this is probably related to the same bug that is causing people to lose their ISDN and have the same loss of radio connection.

Hello. FWIW: Not quite the same problem, but the fix for me might work for you by chance.
When I got my unlock code from T-Mobile then applied it, my phone did register with the T-Mobile network, but it could not receive phone calls.
Using her phone, my girlfriend was kind enough to help me test various scenarios: phone calls in, out; sms in, out; GSM or Wi-Fi; etc. We narrowed it down to no calls in on GSM at least.
Like you I tried rebooting, but I did not get as far as re-flashing, etc. What I did try on a hunch was clearing all user and system apps' cache with Titanium Backup. VoilĂ ! It worked.
I hope that helps you with your phone (assuming you use Titanium Backup.)

[Q] S3 on Bell: not registered on network

hi everyone,
I got my S3 from Bell two weeks ago, it worked fine most of the time including calls, sms and data.
but occasionally for whatever reason the phone cannot make call or send sms, no ring for incoming call also. it shows "not registered on network" when I try to dial. at the time showing this error, there was signal on the bar.
maybe after long time, it can registered itself into network again, but most of the time, I just restart the phone and it works fine again.
I called Bell and they asked me to replace the SIM card, so I did, but I still see this error. So I think it is not SIM issue.
anyone has idea what the cause could be? or is there anyway to fix it?
I tried to search online before I ask, just couldn't find a solution so far.
so post here and hope anyone can help,
thanks for the help in advance.
I've had this issue as well.

I had this problems with rogers as well. Same as you I contacted rogers they told me to remove the sim and replace it. Worked for a while but kept happening. I got fed up and rooted then installed kyan rom and haven't had the problem since. Not sure if it was rom based or if the factory reset before flashing resolved the issue but haven't had it since. Hope someone figures this out though because it's annoying especially on a new phone that is stock.

Had this problem on bell a few times the first 2 weeks I had my phone. Went to the bell store and without hesitation they told me to change the mobile network mode from gsm/hspa+/lte
To just gsm/hspa+.
Reason given was the Lte network where I was using my phone (west island, montreal) wasn't strong enough. So my phone would switch between networks until eventually it got in that state. Personnaly I think the problem was more signal penetration into the computer lab I work in.
It's been 2 weeks stable so far. A co-worker reported the same problem to me last week and he took my advice and hasn't had the problem since.

Thank you very much for the tip. I was wondering that too, because I noticed that the network icon at top bar keep changing between H+ and LTE by itself. and I wonder why too.
I will try and see what happened.

SAMSUNG i747M not registered on network
I had this samsung s3 i747M from canada. Got it unlocked here in Pakistan. Placed a local sim in it. It recognizes the sim, registers it, makes calls, but then after a while, it shows "not registered on network". i restart, it registers network again, then loses it again. It keeps doing it. sometimes it is registered on network, but can't make or receive calls.
I have tried a number of things but the problem is not resolved and i'm fed up to the point that i want to throw this phone away.
The original rom had android 4.3
here's the list of things i have tried.
* changed the network mode to "GSM only" and "WCDMA/GSM (auto connect)" - NO USE
* Factory data reset a few times - NO USE
* tried a custom rom (it was so bad, i deleted it, don't even remember the name) - NO USE
* stock rom 4.4.2 from "sammobile.com" - NO USE
* tried flashing different modems from "http://forum.xda-developers.com/showthread.php?t=1831898" - NO USE
* tried changing the options from *#2263# to my network's specifications - NO USE
* tried sims from different networks - NO USE
PLEASE IF SOMEONE CAN HELP ME OUT HERE, I'M DESPERATE
@qamar_ish, what ROM is on your Samsung phone?
Originally it came with android 4.3. Currently it has this kitkat rom, which i downloaded from "sammobile.com".
the filename is this:
I747MVLUFNK2_I747MOYCFNK2_I747MVLUFNK2_HOME.tar.md5
It said on the webpage that it is the stock rom for SGH-i747M

Does your carrier require an AWS-compatible phone? Does the i747m support all frequencies provided by your provider?
I'm not sure about whether an AWS phone is required or not. But it certainly supports all the frequencies provided by the networks here. I checked it by using the code *#2263# and the options have the frequency supported by my networks here, that is "ufone" and "warid"
PS. I'm not an expert on this thing, whatever i'm doing, i learnt it during the last week..

It looks like your phone does support your carrier's frequencies.
Does your phone show the imei# from the dialpad? Is it possible there is something wrong with the phone's imei #?
It does show the correct imei when i dial *#06#. It had lost its imei initially when i got it unlocked, but got it fixed from someone.

Do you know why it lost the imei during the unlock process? Does the imei # in the phone match the imei # on the label under the battery?
I dont know how it lost imei. The guy who fixed it said that the imei is corrupted and he fixed it. Now it shows the same imei as on the back of the device.
I have never had a Samsung phone lose the imei if the phone was unlocked using a code, assuming that is how your phone was unlocked.
Did you try re-injecting the imei with the efs folder? It can be done using nvwriter.
Ok. I will try that. Can u guide me how to do it? Or share a link or something.
And thanx for helping me out here man..

I have downloaded the stock rogers 4.1.1 rom as well as the stock 4.1.2 rom and reflashed my note 2 with odin multiple times to no avail. during the update to 4.1.2 via OTA was flawless, no errors or anything, but after the update, my phone became completely useless!!

It's funny because my phone, AT&T, has recently been doing the same thing. It jumps from 4G to G then 3G then completely no signal. I'll wake my phone and there are no bars but if I keep it awake and use it for a bit then the signal comes back but very very faint.
Check your apn settings. If they're non existent then jet Google them. Should take 30 seconds to find

What is showing under settings about device? Is your baseband showing unknown or check if you still have your imei by typing *#06# try flashing Rogers modem.
same thing was happening to me (although not after the update, as I was flashing cleanROM & skynote) Keep in mind though that I was using those ROMs for quite a while before this started happening to me.
I was never able to fix it, so I flashed it back to stock,and took it to an AT&T store. The guy there switched out my sim and the signal came back immediately. However, I walked out of the store, and within 5 minutes, I was getting absolutely no service. I turned around and went back to the store, and they are doing a warranty exchange on the phone for me.
replacement phone should be here tomorrow. I also got a $100 credit on my next bill because it has been like this for a few weeks.
To the op, if your phone is stock I would take it to your carrier and get it sorted out.

sounds like a missing apn to me. You could do a simple search on google or xda to get the correct apn for your phone & carrier. Input the info in and that should do it. Otherwise, bring it to the store and have them do it for you, but make sure you didn't mod your phone.

Same exact thing happened to me. Got a nexus 4 while my note 2 was in repair. Got it back and was having the same problem. I went to the ATT store and they gave me a new sim card..worked in the store...walked out and 5 minutes later no signal. I really don't know what to do at this point. I had flashed with Cleanrom and Paranoid but when this phone came back they replaced the mainboard so everything is stock again. Really weird. I think I might say see you later to ATT.
Any other ideas please comment.

[Q] [SOLVED (sorta)] Sgs3 i747m Service issues

First of all this is my first time posting here on xda but have read a lot of things on this website, and i apologize if i have placed this in the wrong area.
I have seen other threads about this issue but none seem to be quite like mine.
So i had cyanogenmod on my galaxy s 3 att/rogers, I had it on my phone for a long time pretty much the entire year i have had the phone, when randomly last night my service just stopped. I cant make phone calls, text, or use data. But my wifi still works. so basically my phone turned into a tablet.
Things I have tried to fix this:
1: restored using nanndroid backup (no effect)
2: flash a different rom "PAC Rom" with its kernel (no effect)
3: Restored phone to complete factory defaults using odin (no effect)
4: Tried different SIM card in my phone to see if it would work (no effect)
5: Tried my SIM in different phones (worked)
6: Restored phone to factory default using samsung kies (no effect)
So can you see my delema? No matter what i try the service just will not activate and only says "rogers emergency calls only". this phone is only around a year old.. This isn't a common thing to happen is it?
Anyways I would be very, very happy if anyone could help me fix this problem. I apologize if i get back to you slow as i have to go to work in a couple minutes, my boss is probably going to be pissed I have no phone. :crying:
Nothing? Nothing at all?
I had similar issue I just solved. I had only lost data however. I would suggest maybe checking your apn settings. It maybe flash a modem. I was able to make calls/texts no problem but no data at all. I Google the apn settings and now everything works great

Apn settings were all right. Not sure what has happened.. rogers told me the phone was toast but I have a hard time beleiving that from someone who looks at my phone for 30 seconds and says that. Either way I'm picking my note 3 up friday. Not through rogers, since they were a royal pain in my wallet. Bell ftw
Not really sure if I should mark this as solved due to the fact its not?

[Q] Help with Verizon SCH-I535 Phone to use on T-mobile

Hey everyone and thanks for taking the time to read this,
So the story goes as so: After doing some research couple months ago about the capability of the Verizon Galaxy S3 to work on T-mobile, i purchased it, and got it to successfully work on T-mobile(texts, calls, wi-fi). The problem is, i just recently upgraded to include a data plan, and i cannot access the internet, despite taking my phone to my cell phone dealer and contacting T-mobile.T-mobile even sent me a guide to do a mastery reset to factory in hopes to solve this problem, only to tell me afterwards that the phone version SCH-I535 is a "verizon locked-software" and i won't be able to set up an APN to work on the T-mobile network. This was all due to the fact that i was not able to set up a APN for T-mobile, and every time i tried to access it through setting, it brought me to a blank black page with the only option of "Reset to Default". After reading other forums and talking with some people, many have suggested i take this issue to XDA to find a solution.
So, here i am.....Does anyone know if it is possible for me to break/root/ or whatever it is called so i can successfully access the t-mobile network on my phone? Preferably an easier guide since i am sort of a newbie at this sort of stuff.
Thanks again for reading.
Before your Contract change, you were able to receive and make calls successfully with T-Mo Sim right ? Even now you can make calls too correct ? The reason I am asking this is to be able to check if you are really unlocked off of VZW. If you are not unlocked, then that would be the first step.
You are right, the APNs do drive Data Connection. If the stock firmware does not allow you to change APNs then you will have to root. Please post a screen of your Settings > About phone that shows your Rom Version, Baseband and Kernel.

Hey Perseus, thanks a lot for taking the time to reply. I bought the phone in the summer off someone who had verizon. I have always had T-mobile, and considering this phone is GSM, i decided to buy it because it would probably work for T-mobile. I had the phone unlocked, and i am currently using it to make calls, texts, and even use wi-fi with no problem. The only problem at this time is that i recently added a data plan which i cannot currently use. Here is a screen shot of what you have requested.
Thanks again
First try
Settings > More > Mobile Networks > Preferred Network Type.See what it is set to. Change it to LTE/GSM/WCDMA if needed. See the other option System Select as well.
Also separately try the following.
Hit ##DATA# in the Dialer. In the subsequent Menu choose EDIT > OTHERS > LTE APN
If all fails, please Root the phone and then try. The way you go about is
1. Flash a Custom Recovery via Odin. Make sure the version of Custom recovery is for your model D2VZW not D2TMO.
2. Flash a SuperSU zip file via Recovery and then hit fix permissions in the recovery.
Try the APN Settings after that. IF you can actually access them, then set them according to this link.
If all the above fails, I'd suggest a custom Rom for d2VZW.

Ok, so i tried to changed it to LTE and i got no service at all, so i switched it back to Global. I also tried the dialer thing several times, and got the " connection problem or invalid MMI code"
So i guess i am going to have to root the phone? Does anyone know a good video tutorial or written tutorial on how to safely do this? Also, what exactly is rooting?

You have to enable the mmi codes to use them. Anyway as stated above your reply you will never get 3g or 4g just edge (seen it personally) which is pretty darn slow.. Not worth it if you ask me and be paying for data.. If you still want to root it and keep trying to add sons check the Verizon forums.. They could probably help you a lot more than on this side of the forums

Guys, he is not getting ANY data signal at all. His problem isn't getting the specific icon but being not able to change APNs.
@HackThisThing, you are better off following up on Verizon Device forum. That forum does have a video tutorial for Rooting. Here's forum link.
I don't think you will be able to change APNs without rooting. I checked with a buddy of mine who has the same device as you.
Here's a good answer to What is Rooting ?
Even if you CAN fix it, why bother if you can only get 2G? I'd sell it or trade it for a phone that's more compatible with T-Mobile 's network instead of paying for data and only getting dial-up speeds. I get that solving problems is fun, but OP do you want to live with only 2G?

I don't agree with that assessment. Just like the T999L phone, this device will work on LTE Bands just fine. OP just needs to wait for LTE to be rolled out in their area. There's a coverage map and roll out schedule on T-Mo website and the T-Mo News blog.
It's worth a look, but could still leave them with patchy coverage. If it's going to be a while, why wait when it's not hard to just trade the phone? I guess I don't see a reason why hold out on getting a Verizon phone to work when you could just get one that works now with little to no monetary loss. It's just a Verizon S3, not really something worth "waiting" for when they could get the same thing but more functional on their network of choice.
They made an honest mistake and waiting might give them "good enough" service - but other than that they're stuck with dial up speed only and risk bricking a phone they could just trade or sell now.
Maybe I'm just impatient and risk averse.
