2. Setup and Activation
Before using your T-Mobile SIM card, it must be properly sized for your device and activated with T-Mobile service.
2.1 Sizing the SIM Card (Triple-Cut Design)
Your T-Mobile SIM card features a "triple-cut" design, meaning it can be adapted to three different sizes: Standard, Micro, and Nano. Identify the correct SIM card size required by your device before proceeding.
- Determine Required Size: Consult your device's manual or check the existing SIM card slot to identify whether your device uses a Standard, Micro, or Nano SIM.
- Punch Out Correct Size: Carefully punch out the SIM card from its larger frame to match the required size. Apply gentle, even pressure to avoid damaging the SIM card's contacts.
- Insert SIM Card: With the device powered off, insert the correctly sized SIM card into the designated SIM card slot. Ensure it is oriented correctly according to your device's instructions.

2.2 Activating Your SIM Card
These SIM cards are unactivated upon purchase and require activation with T-Mobile. As of July 1st, 2020, these cards are primarily compatible with postpaid cellular service. Contact T-Mobile customer service to activate your SIM card and select a suitable service plan.
- Contact T-Mobile: Call T-Mobile customer service or visit their official website for activation. You may find contact information on the SIM card packaging or T-Mobile's official website.
- Provide Information: Be prepared to provide the following details to the T-Mobile representative:
- The IMEI number of the device you intend to use the SIM card with. This can usually be found in your device's settings (e.g., About Phone) or by dialing *#06#.
- The SIM Card Number (ICCID) printed on the SIM card itself.
- The zip code where the service will primarily be used.
- Select Service Plan: Discuss available postpaid service plans with the T-Mobile representative and choose one that fits your needs.

4. Maintenance
SIM cards are durable but require minimal care to ensure longevity and proper function.
- Handle with Care: Avoid bending or creasing the SIM card, as this can damage the internal chip or contacts.
- Keep Dry: Protect the SIM card from moisture and liquids. If it gets wet, allow it to dry completely before reinserting it into a device.
- Clean Contacts: If necessary, gently wipe the gold-colored contacts on the SIM card with a soft, dry, lint-free cloth. Avoid using abrasive materials or harsh chemicals.
- Store Safely: When not in use, store the SIM card in its original plastic frame or a protective case to prevent loss or damage.
