call to the tmobile customer service and ask for a unlock code , they will ask you for your imei and an email, and they will send the unlock code to you!!,

That only works if you have had T-mobile for at least 3 months and you have a post-paid account, i.e. not flexpay or T-mobile-to-go. And you can only do it once every 90 days, whether you get a different phone later or not.
