How to get the unlock code prompt on AT&T Nighthawk MR1100

I have a AT&T Nighthawk MR1100 through OTR Mobile. They are switching to T-Mobile based service so I had to get the unlock code and a T-Mobile post paid SIM. When I put the T-Mobile SIM in and power i...

    If you can connect to T-Mobile network without entering the code, your device was unlocked.

     

    Thanks

I did not purchase my MR1100 from OTR, but it is branded AT&T and locked.

    Depending on where you bought it, from a retailer, AT&T or one of the companies that sold them as part of fraudulent plans, AT&T may unlock it...  But if it's not a legitimate AT&T device it's not going to make a bit of difference whether you use the IME OR the phone number when you try to unlock it at AT&T...

     

    Had a lengthy conversation a couple days ago with one of their people who provided some information about what was actually going on with a bunch of resellers...  Dead phone numbers, phone numbers belonging to a phone, IMEIs that have been spoofed...  AT&T isn't going to help.

     

    Been there, done both, makes NO difference.

     

    And yes, CellCorner is the other one...  Before you give them money, look around for posts about the success people have had with them...

      Update: Successfull unlocked.

       

      After OTR mobile released the AT&T number associated with my MR1100, approximately 48 hours, the AT&T unlock portal accepted my request to unlock via IME number.  Then 48 hours later it was approved and i was sent an unlock code and instructions.   Putting in a new sim card shows the modem locked, access the MR1100 admin page gives me the option to enter an unlock code and submit and it was accepted.  Unsure if one needs to do so every time the sim is changed or not.

       

      No need to pay a third part many dollars to get software that will not even work as dc-unlocker.
