[Q] Please Read, need help unlocking n900T - Galaxy Note 3 Q&A, Help & Troubleshooting

Ok, so I purchased a used tmobile n900T which is no longer on a subscription. I want to put this phone on straight talk, this is what I have done so far:
1: Rooted using towel root
Attempted to unlock using the method explained here: http://forum.xda-developers.com/showthread.php?t=2471742
I did everything exactly as explained in the directions, but when I boot up using the AT&T Straight talk card, it asks me for a sim unlock code....
I went to one of the sim unlock websites: cellunlocker.net and the instructions told me I had to have the note 3 on a tmobile plan before I can get the unlock code?
any suggestions? thank you for your help.

Any suggestions on what to do next? Any help would be apperciated.

yes you did unlock your phone otherwise when you put your tm sim in it would ask for the lock code.

[Q] Rooted & unlocked i337 asking to insert sim

Hoping someone can help me figure this out.Created a new topic because it seems a bit different from the other "no sim" topic.
I have an i337 on MF3 that was rooted and unlocked using jortex's method and chainfire's region unlock.

I used it on Tmobile's network for about 16hrs without problem, then it suddenly started showing emergency calls only and asking to insert sim. I've place the tmobile sim in another phone and it worked fine, also put an unactivated AT&T sim in the S4 and it sees it. The phone is still booting up with the samsung custom screen. Any ideas on how to fix?
Thanks in advance.

sgh-i437 rooted and running cm-10.2-20130925-UNOFFICIAL-expressatt-still locked

I have a Samsung SGH-i437 that was a contract phone from AT&T. I wanted to unlock it for use over seas, so I rooted the phone and installed CyanogenMod cm-10.2-20130925-UNOFFICIAL-expressatt but the phone still has a carrier lock on it. I now have a unlock code but can not get the prompt by using #7465625*638*CODE# because it give me a no network message. When I insert a different sim it does not recognize it. It only has the icon for the sim with a ? make on it.
Any help would be appreciated!

How to unlock without the device unlock app?

Hi All - I recently bought a Samsung Galaxy S8 from someone else. It worked fine when I was with T-mobile but when I moved to another network and popped in a new SIM, it asked me to "Enter network unlock code". I figured it must be locked to T-mobile so I reached out to them. They said my account met all the unlock criteria and said they'll send me instructions via email. I got the email two days later saying I need to use the "Device Unlock App". However, there's no such app on phone and there's no way to install it either (its not in the Play Store). I went back to T-mobile and they said since the device wasn't purchased through T-mobile, its not be a T-mobile "branded" phone. My questions are:
1. If its not a T-mobile branded phone, why does it only work on the T-mobile network? I checked its not rooted. It doesn't have any T-mobile apps and doesn't show any splash screen with the T-mobile logo.
2. Someone said that Samsung GS8 locks to the network of the first SIM you put into an unlocked phone. Is that true?
3. T-mobile says they've "whitelisted" my IMEI, so if I can somehow get the Device Unlock app I may be able to unlock it. Any idea how I can do that? Do I need to flash the firmware and install the T-mobile version or is there another way.
Thanks!
If you need to app, you can try here: https://support.t-mobile.com/docs/DOC-14011
However, as your phone is asking for the unlock code, the app might work but not unlock your phone.
You really need to do a network check and see which network is your phone actually locked. If your phone needs unlocking code, you might need factory level codes.

Need help getting my AT&T sim card to work on my T-MOBILE ONEPLUS 6T

i know I posted earlier about a different issue, sorry for spamming the board.
I have a T-Mobile 1+6t with 9.0.15, i have been searching and tinkering all day and am still very confused about how to do this. From what I've seen, it is definitely possible, and every guide i've looked at is very simply laid out but i keep running into issues. Firstly, I have successfully converted to international version using the MSM tool. I thought this would be enough for my sim card to work but it is still not working. Now I am reading a bunch of other things about sim unlock and bootloader unlocking. Sorry but I am a noob at all of this. Can anyone point me in the exact direction in order for me to get my AT&T sim card working in my T-MOBILE 1+6t?
So my information is : TMOBILE 1+6t converted to International, running 9.0.15, and need to get AT&T sim card working.
What Ive done so far: converted to international.
What am I missing?
Before the conversion, you needed to get the carrier unlock code from TMo.
If you have not done that, you need to convert back to TMo firmware, get it unlocked from TMo, use the unlock app to unlock. After that you can flash the international firmware.

is there a way around that? before i converted, i did see the unlock app and tried to use it but it said the device is not eligible. I called t-mobile and they said they'd send me instructions to unlock. But i am not totally sure if the phone is paid off, it was my gf's ex's phone who i don't know and she doesn't want to talk to
Right now i am trying something else - from the guides i've gathered, you need to be on 9.0.11 to unlock the bootloader and need the bootloader unlocked to unlock the sim, so:
I am downloading the files to downgrade to 9.0.11 international, unlocking the bootloader after that, then using this guide to unlock the sim. will this work?
There's no workaround.
If someone stole my TMo op6t and tried to use it in another network, he or she can't unlock it, as I own it and it may not have paid off.
Actually you can follow this guide ( https://forum.xda-developers.com/oneplus-6t/how-to/guide-sim-unlock-t-mobile-version-type-t3915269 ) to remove the Sim lock. In essence you'll convert it to international, erase the two modem files containing the Sim lock info, revert it back to the TMO version. Apply to OnePlus for your unlock token, wait a week to get it, then unlock bootloader. End result is a fully bootloader and Sim unlocked phone. Or if you're not interested in unlocking the bootloader you can skip the last part. You'll still have an unlocked phone.

Hey I actually successfully followed this guide last night and am now typing on my 1+6t international w/ unlocked bootloader + sim unlock. I unlocked the bootloader using a different guide. One question: will updating my phone affect this sim unlock? Because I know you need 9.0.11 to unlock the bootloader, and you need an unlocked bootloader to use this sim unlock guide. I know there is an update available, Is it safe to update?

The Sim unlock sticks permanently, I've updated several times after doing the SIM unlock both on the TMO version and the international version and have had no issues at all. I flipped back and forth between the two trying to decide which I wanted to run. Stuck with the international just for the more consistent updates.
