I can't find unlock code

I got nokia lumia 521 that is locked to T-Mobile carrier. I am in Ethiopia and want to use Ethiopian Mobile network but when I inserted Ethiopian Sim card it requested me to enter unlock code or pin but the puzzle is I don't have either 8 or 20 digit unlock code! So where I can get that code since I am in Ethiopia? Please try to help me how to get the code.... Thanks!

Re: I can't find unlock code

The unlock code should come from T-Mobile. Were you a customer of theirs in the US? If so they will send an unlock code so long as you don't owe them for service or the phone. https://support.t-mobile.com/docs/DOC-1588

Otherwise you have to use an unlock service and that costs money, plus takes time. Research which ones are good, fast and reputable before paying.
