I have a Verizon galaxy note 2 and I ordered a t mobile sim card so that I can unlock it and use it possibly on another carrier. When I put the Sim in and dial *#197328640# I get ussd coding than an error comes up of invalid mmi code. I try again and the same things happen. I have my phone rooted but have stock Rom on it and android 4.1.1. Any help would be appreciated. I have attached a screenshot of my baseboard versions and such.

Hi, i have some problems with No Sim Card detected on Samsung Galaxy S III I9300 from T-Mobile (Austrian)
Firstly i unlocked the phone at the shop and was really unlocked on all sim cards but than i did a factory reset and the phone no longer detects sim card from other carriers, it only detects sim card from T-Mobile, It dosen't even shows the menu when you turn on the phone for network unlock.
I tryed using those secret codes to show the network unlock menu but they didn't work since the phone was updated to 4.3 firmware.
So i followed this guide on androible downgrade-galaxy-s3-i9300-android-4-3-android-4-1-2-jelly-bean-firmware
To downgrade to 4.1.2 firmware along with provided modem file. The secret codes now do show menu's but when i click on UMTS RF NV it says it's not supported.
Also instead of downgrading to T-Mobile 4.1.2 Firmware i downgraded it to Orange 4.1.2 Firmware hope that dosen't effects it in anyways? Phone otherwise works just fine IMEI Number shows OK.
I tryed 2 different SIM cards from orange none of them worked, it only detects SIM from T-Mobile.
To recap it all agean: I wish to unlock this phone so i can use different SIM card's but the phone is on NO Sim card, emergency calls only but when i insert T-Mobile Sim it works, Also there is no Network Unlock Menu shown durning turn on or reset since i already Unlocked the phone once with a code. Does anyone has any clue how to fix this or unlock it without rooting the phone.
Hello all,
It has been awhile since I've been on here. I apologize if I am posting in the wrong section (this forum has changed so much over the years).
Anyways, I am currently a T-Mo customer and just got a Metro PCS Samsung Galaxy SGH-M819N because I thought I could simply flash a rom that would allow me to use T-Mobile sim card. However, it turns out that it may not be that simple.
Can someone advise whether or not I am able to unlock the sim (without paying it through sites such cellunlocker.net) via flash? If so, would you be kind to direct me to the site or page which gives directions?
Thanks,
eastbay80
oK, i paid
4update:
I am ended buying an unlock code via eBay for $14.99. I enter the code and the phone no longer asks for SIM unlock code BUT now it does not register with any carriers.
i inserted my t-mo sim card into the phone, go to settings, and tried to automatically and manually connect to the tmobile network but keep getting the "unable to connect at this time. try again later" message.
i contacted tmobile via chat and provided imei number and sim card number but was still unable to connect.
i flash backed to stock firmware 4.4.4 and still no luck.
i checked my "device info" and under "phone status" it shows my phone number assigned to the sim card but not connecting to service provider.
Any ideas anyone? Please help.

I am able to connect with the stock Metro PCS apn.
I am also able to use TMO apn as well.
Make sure the apn is correct.
Go to more networks and then mobile network.
Hi all,
I have a Huawei Mate 2 from Freedom (Wind) Mobile. I have updated it to Lollipop 5.1 by unlocking the bootloader. In fact I made a guide for it a while back.
https://forum.xda-developers.com/ascend-mate2/general/guide-step-step-wind-mobile-canada-t3387490
Recently in Canada the cellular service providers are forced by law to give us an unlock code for free. After unlocking the phone would work with any service provider. This phone has a pretty big battery and would be ideal for a travel or backup phone.
I successfully got an unlock code from Freedom (which was pretty easy). I then put in sim cards from another provider (Koodo, Fido, etc). However the screen for me to enter the unlock code never popped up. It just say "no service".
I tried to manually set it up, by clicking the notification. "No Service: Selected network (Telus 3G) unavailable". However it won't register. Neither did the unlock code entering screen ever pop up.
And under data settings it say no SIM card. However the phone works perfectly when I insert my Freedom SIM card. But when a foreign SIM card was inserted it just say no SIM.
My question is has anyone been able to unlock this phone under Lollipop 5.1? How did you get to the "Enter Unlock Code" screen?
I also wonder if anyone has any luck unlocking with the original Android 4.3. If someone did, maybe I should flash the phone back to its original OS.
Thanks in advance!
