Introducing Your T-Mobile Subscriber Identity Module (SIM) Card
The SIM card contains a computer chip that identifies you to the wireless network
and contains information such as your phone number, service and registration
information, and contact information, as well as the memory to store speed dial
numbers and text messages that you receive.
Introducing Your Personal Identification Number (PIN)
Your SIM card comes configured with a PIN to lock it against unauthorized use.
The default PIN code is 1234. Type this default code when your device prompts
you. You can create your own PIN when you activate your SIM card.
You have up to three attempts to type the correct PIN and unlock your SIM card. If
you fail to do so, your SIM card will be locked, and you will need to call Customer
Care at
1-800-937-8997 for a code to unlock your SIM card and reset your PIN.
