Lost t-mobile sim card wont to block it for free
You are out of options as far as what you can do now that the phone is out of your possession.
That is why you set up a security code for the phone, so if it is stolen they have a hard time of using it.
Sorry about your loss, thank you for stopping by Fixya!

PUK codes are different for all handsets.
You need to call your network operator and give them you IMEI number. They will then be able to tell you your PUK code.
