[Q] Help!!I have atrix 2 AT&T locked

I have a Atrix 2 AT&T sim locked .If I install a custom rom like Supercharged Atrix, will be unlocked to any network mobile ? I live in Costa Rica, I bought my phone on ebay like new, unmodified and without contract,but I dont have money to buy the unlock code in cellunlocker.net. It is necessary to unlock the bootloader to unlock the sim card ? I Search in all the forum to see if the doubt was resolved but did not find anything.Somebody help me please!!!
No, it's not necessary to unlock the bootloader to have your sim unlocked.
That is a network provider deal.
Our bootloader is currently "UNLOCKABLE".

I don't think installing custom ROM will unlock the phone for all carriers. You have to do unlock separately if you want to use with any provider other than AT&T.
SIM unlock is entirely separate from changing roms, the bootloader and all that stuff.

Currently our bootloader is LOCKED. Installing the SC ROM will not unlock your phone. To unlock it search on eBay for an unlock code. This right now or the only way to unlock your phone.

He means to SIM unlock the phone, not bootloader unlock....
a sim unlock is about $16.00 USD, just search ebay for atrix 2 sim unlock code.
I got mine from here

If it's an unlocked GSM phone, it will work with any GSM carrier. I don't know if your phone is carrier locked or not, though. Also, custom roms don't control which carrier you can use.

You don't need root or ANYTHING to unlock your phone.
1) get SIM that is not the network the phone was originally on
2) buy unlock code from local dealer or trusted ebay seller. You have to give them your IMEI I believe
3) put that SIM in and when prompted, enter unlock code. Phone is now unlocked for any SIM card for eternity

ZTE Avid N9120 vs. the ZTE Blade, Unlock

I've downloaded several ZTE Unlock programmes, most of which either don't work or only Unlock the ZTE Blade.
After some research, I noticed the specs are virtually identical.
Can anyone tell me if the Unlock codes for the ZTE Blade will Unlock the ZTE Avid ??
Also, my device manager lists the ZTE Avid as a cdma phone, yet it DOES in fact have a Sim card.
Can anyone describe the Unlock procedure and if I can use the phone on a gma network ??
I'm on MetroPCS now and wish to use TMobile or AT&T, which is down the street from me.
This phone is completely custom, so I don't wanna change phones, just Unlock this one, please.
Please advise.

Pls pals i need help on how to unlock sprint samsung galaxy note 5 android 6.01. Am in Ghana and i dont my gifted sprint note 5 is giving me invalid sim card when i put in a local gsm sim card
First you should have called Sprint to allow your phone for international, stating that you will be using a local sim card. If you did that then try a new sim local sim. Or just Google for note 5 unlock methods.
