Replacing your damaged SIM card with a new T-Mobile SIM card is the only practical way to keep your phone working on the T-Mobile network. Just remember that locked T-Mobile phones cannot accept SIM cards from other carriers.
• Visit a T-Mobile store to request a replacement SIM card for your damaged one. Your old and new SIM cards will have the same number.
• T-Mobile SIM cards are required for network-locked phones. Thus, your phone will recognize and work with the new T-Mobile SIM card.
• T-Mobile phones won't work with other SIM cards because they're network-locked. If you use a SIM card from another carrier in a locked T-Mobile phone, it won't recognize it and won't let you make or receive calls, text messages, or use data.
• Replacing your damaged T-Mobile SIM card with a new one keeps your phone on the network with the same number and functionality.
• An alternative to physical SIM cards, eSIMs can last longer. eSIMs are built into your device and prevent SIM card damage. T-Mobile's eSIM support and your device may determine eSIM availability.
