How long do sim cards last?

SIM cards can last for many years, often up to a decade or more, as long as they are kept in good condition and used regularly. However, if a SIM card is inactive for an extended period—typically 6 to 12 months—it may be deactivated by the carrier. Additionally, technology changes, such as the transition from 3G to 4G or 5G networks, may necessitate upgrading to a new SIM card. Always check with your carrier for specific policies regarding SIM card longevity and activation.
