Nokia Lumia 521

contacting the service provider is not an option. But I did that and they do not open locked cell phones.

I assume this is a question of "How do I unlock this phone?"

First you say contacting the service provider is not an option...but then you did contact them? That's a contradiction. I'm not 100% sure what you are asking for? The T-Mobile pre-paid version comes unlocked (at least in the states).
