US T-Mobile Prepaid SIM Activation Guide

This page is a step-by-step guide that explains how to activate a T-mobile SIM card:

Important Notes:
Make sure your phone is unlocked from your carrier
Most carriers sell their phones ‘locked’ so they only work with their own SIMs.
If you need any information about this refer to unlock info here

SIM will only connect overseas, but will require credit to make/receive calls
After you have followed the steps below, you can test if your SIM connects to the network in your home country (in Australia it does), however to make calls it will require credit in addition to what your plan costs (overseas roaming calls aren’t included in the plans).    

Activation

Your birthdate and IMEI (dial *#06# to display your phone's IMEI number) will be required.
