Not all SIM cards are compatible with all phones. Compatibility depends on the SIM card size (such as standard, micro, or nano) and whether the phone is locked to a specific carrier. If you plan to use a different SIM card, ensure your phone is unlocked and can support the desired network bands. Checking these factors can prevent issues and ensure seamless communication.
