S3 no reception? - T-Mobile, Samsung Galaxy SIII

My friend got a phone from T-Mobile s3 few weeks ago and unlocked it to use it here in Canada in mobilicity network. But it has like 0 reception it gets reception for few mins than goes to 0 bars. Is it a radio issue or something else? Any help would be greatly Appreciated. Thanks!

Are you sure the unlock was successful? Im not sure how it works in Canada but could it be blacklisted?
While it shows signal does it work for calls and data?

Yes unlock was successful and recognize the network. Gets reception you can make call after few mins loses it and goes to 0 it's not blacklisted as it was purchased outright from the retail store. Right now there is no Sim card on phone and it shows 4 bars.
and for some reason this is the newest s3 i think cause usually its t999v this one say t999l

You might need a new sim card. And the T999V is only sold by the Canadian carriers. The T999L is the updated lte model of the original T999.
After unlocking were you able to use a sim from another carrier and have it work with zero issues? If you only tested it on the network you are reporting problems with that is not confirmation of a successful unlock. Try a sim from another carrier and see if it works.
If it is unlocked then it sounds like an old sim card type issue.

just tried my sim card same issue and we tried with 2 other brand new sim card from ssame provider. i just flashed this March 2014 - 4.3 JellyBean - New!
Note: This is based off of the stock image TMO T999LUVUBNC1
Download :: Download - root66_TMO-L_T999LUVUBNC1.7z through odin thought it might be radio issue but same thing.
her daughter has the same s3 with 4.1.2 and works perfect. can i downgrade through odin to 4.1.2? i think md5 modem might be better.

Unfortunately no. Once you flash 4.3 there is no going back. If its not working with any of the sim cards, try one from another carrier if possible.
Kinda sounds to me like its not unlocked. How did you go about attempting to get it unlocked?
Sent from my SGH-T999 using Tapatalk

She will come to pick the phone today I'll ask how did she unlock the phone. But if it wasnt unlocked how does it recognize the Sim? Can you suggest me a modem? But I will ask how she unlock it and let you know. Also when I flash the new 4.3 it didn't erase the call history and also when I reset the phone it doesn't seem like it resets it cause the call history's are still there.

You can only use the 4.3 modems now. When you flash firmware it doesnt erase your data. Not sure why it didnt on a factory reset though, unless its stored on sd.

sim card will not register

I traded a note for a t999 last night, but I was unable to immediately check phone connectivity due to not having a micro sim handy. So today I get a micro sim and call my provider, (simple mobile), and they change my sim number for me.
My card will not register with the network. i get bars that show signal, but phone information shows no service. I have no data even with the corrrect APN. Simple Mobile Tech support says they have registered the SIM but it does not show as connecting.
I went to tmobile and they used one of their sims on the phone, but again, no registration.
The phone is rooted, I can boot it into CWM.
Im thinking that the prior owner messed something up, possibly by changing a radio/modem or something. Im not sure I can even warranty repair it via Samsung because he rooted it.
Does anyone have any suggestions? PLEASE?
Odin back to stock?

Sounds like you have a broken pin in your sim slot. I'd bet money on it. I think there's suppose to be 6 and if 1 breaks this is what happens.

i tried flashing back to stock using Odin, but it makes no difference. flash count shows 2. Does this mean the phone is not covered under samsung warranty?
You can reset the flash counter. I believe the thread is in android development on how to do this.

Using AT&T sim on blacklisted T-mobile GS III

Hey guys,
I got scammed on craigslist and the guy won't respond. So I bought a T-mobile Galaxy S3 and it worked fine for over a week until 2 days ago when it stopped connecting or registering to the T-mobile network. I found out from T-mobile it was blacklisted as stolen/lost that day. I called to confirm the phone wasn't stolen or lost when I bought it. The T-mobile store says there is nothing they can do except offer me a new phone from the store to pay full price.
Can I unlock a phone marked as stolen/lost using an unlock code and use it on AT&T?
I tried searching the forum and I found a thread about a guy who already had the phone unlocked so he was able to use it on AT&T but in my case, the phone is not unlocked yet but is blocked from T-mobile networks.
Thanks in advance,
Buzz
Well if you unlock it before the whole illegal thing starts you can use it on AT&T.

If I unlock my T-mobile phone, can I keep the T-mobile stock rom or do I need to flash it with the AT&T stock rom?
If you are on stock, why dont you just dial *#197328640# to go to phone control menu, then network lock and turn off the network lock. If you do a google search for unlock galaxy s3 xda forum u ll see it.

1111+ Thats correct I have tried every rom out there from att and it worked on my tmobile s3. Now for the op. looks for the thread on general there is one that shows you how to unlock your phone without a code. It was meant to be for the note2 but it worked on all us s3's I have mine unlock that way put in my friends att sim and it worked fine only thing that the speed its a little slower not 2G though. And thats because att's 4g its 20ish not 42.
Any ways. If you were called tmobile and talk to a superviser they can change the IMEI number on their system and the phone would come back to work in 48 hours.
I know because It have happened to me too. It doesnt matter if you have your tmobile sim on it for at least a day tmobile computers will register that phone onto your network.
P.S the only thing that will changed from a ATT rom is that build.prop It will show that its an att rom but you can edit it to d2tmo with root explorer
Just don't flash other modems from other carriers that will Brick you.

[Q] s3 downgrade help needed

I recently acquired a t-mobile galaxy S3 (t999l)running stock 4.1.2, however my current provider is metropcs and in order to use it i have to unlock it. I currently dont have the money to pay for that so i want to downgrade it to 4.1.1 to do it for free. I was wondering how i could go about downgrading step by step. I would also like to have it rooted.
There is no 4.1.1 for t-999l.. And you don't need to unlock T-Mobile phones to use them with metroPCS.. I know because I've worked for metroPCS.. In other words, you're good to go!!

[Q] help with galaxy s4 not registered to network

gf reported her phone lost because it was cracked, samsung sent her a new one so now i want her old one. I put in my sim card but it says "Not register to network" im thinking maybe t-mobile blocked the phone somehow since it was reported lost but I figured there was a work around. Friend told me unlocking the phone and setting it to international radios may help but i have no idea how to do this since im new to the android community. Switching from iphone to android! So yeah, please help!
White T-mobile Galaxy S4 on jellybean, updating it to kitkat though.
Yup, T-Mobile blocked it.. There's no legal way around it, maybe your gf calling T-Mobile to unblock it, but they'll probably charge her full price for the one they sent her.. You could try using a different carrier, but it could end up being blocked again.. You could also sell it to someone in another country, blacklist won't go past the US

international radios, gonna unlock the sim. My gfs mom is probably going out of the country so if i unlocked it, she could use it outside the US right?and if she can i take it as she'd have to use a carrier other than t-mobile to do this though?
You can't use international radios.. And I don't know, but I would think so, using a local carrier should be fine

There are services that will fix this for you. I payed 35$ for my blocked tmobile s4 to be repaired.
I did this with an HTC EVO 3D. It was locked for 2 years so I flashed the phone to a different carrier and it worked. You might have problems with different features but it is posibble to still use the phone. Find a cellular store that will flash it. They normally charge around 50 dollars, give or take.

[Q] Issues SIM Unlocking Metro PCS GS3 T999N

I have bought a service to get an Unlock Code for my Samsung Galaxy S3 T999N which is SIM Locked by Metro PCS. They provided me with some 4 codes: NETWORK, PROVIDER, SUBPROVIDER, DEFREEZE.
When I turn on my phone with a non-metropcs sim, the phone prompts: "PIN to unlock SIM service provider" so I put the PROVIDER code that I got from FATSGSM after hitting "Unlock" I get the following message: "unable to unlock sim service provider"
What is wrong? Could the PIN provided by this service be wrong?
Just an FYI, I am outside the US right now.

Thanks for reply to my post.
This might not be true because if you have the Metro PCS sim card inside, you will not get the unlock box. You only get the box to put the unlock code in when you put a non-MetroPCS sim card.
Can anyone corroborate this information?

He means it may need to be activated with the carrier first in order to be unlocked.. Some phones do require this.. You can try the region unlock app but I'm not sure if it works with s3
Sent from my SGH-M919 using Tapatalk
I used it when I got my replacement S3 a while back and it said the unlock was successful. I have no way to test if it really was or if it also SIM unlocked though. I wouldnt expect it to do so, but in my experience, it is safe to try.
