Just bought a 2nd hand mobile phone that's locked to T-Mobile. How do I change it to my network please, and how much does it cost? Thanks in advance!

Price is depending on make and model.

Some phones you can do for free and some can not. Its make and model dependant.

Your wanting to unlock your phone from what your saying.

Which Make/Model is it and I'll tell you if it can be done by code alone or if you need to take it in somewhere.

I think I'm right in saying it's a Panasonic KX-TU 327, (can't get the info from the 'phone itself, but that's the make and model it looks like.)

Any idea how much it is for that? And where I take it? Thanks.
