I have been with t mobil over 20 years---i paid off my phone and when i tried to leave i had to pay an additional 250---if you call they will tell me my phone is paid off--I did twice when on the line with the supervisor who needed 250.  I have told hundreds about how much I liked t mobil over the years---now I will tell everyone (and I speak with the general public everyday all day long) to avoid t mobil like the plague it has become.  Please for your own sake never use this company.

Here's the requirements to unlock your phone, once you meet the requirements Tmobile will automatically unlock the phones as long as there's no outstanding balance on the account and the account is in good standing.
