How do you activate a T-Mobile sim card?

Answer by  erin86 (14)

Open the back of the phone and also the battery area. You will see a small place exactly the size of the sim card. Slot in your sim card. Then, put the battery back to how it was before and close the phone cover. Find a button i and press about 5second on it until the phone screen turn on.

You don't need to activate it. As long as you put your T-Mobile sim card into a T-Mobile phone, it should be active and working.

T-Mobile like many other network US, need activate. Go T-Mobile web page, on Prepaid case go under Prepaid products and search "Activate" thing, e. g Activate phone. On card body there are numbers what are needed. Also IMEI code are needed, found on your phone sticker under battery.
