SIM Unlock through Software

[crashzz]

I know a lot of phones such as Samsung and HTC allow you to SIM Unlock your device when you root your phone, is it at all possible to do the same with the Nokia Lumia 710? Long story short, I ordered an unlock code for my device and its been 3 weeks and they have yet to give me a unlock code. I was hoping to find an alternative solution that would allow me to SIM Unlock my phone.

From what carrier is your phone?

T-Mobile is the carrier the phone is locked to, I am trying to use it on AT&T.

Do you try with code?

I purchased an unlock code but they told me that they could not locate it from any of their databases. I tried cellunlocker.net, I am trying another seller but I am hoping that I don't have the same issue.

The second place where I ordered an unlock code also said they could not obtain my unlock code.

Any reason why an unlock code wouldn't be listed in a database??

My Telus L800 is sim-unlocked via a code so I am not sure what to tell you really. Have you tried contacting T-Mobile for the code?

SIM Unlock by flashing ROM?

I have a T-Mobile USA locked Lumia 710, would it be possible to unlock by flashing this ROM:

1600.3031.8773.12121
059P8W2: Nokia 710 RM-809 VIVO BR Black v1 (No SIM Lock)


It seems to be built for the Brazilian carrier Vivo.
