SMS messages themselves do not have an expiration date. However, the mobile carriers might set a time limit on how long they'll keep undelivered messages before deleting them, typically ranging from 72 hours to 30 days, depending on the carrier's policy. For messages that have been delivered, they will stay on the recipient's device until manually deleted, assuming no storage issues or automatic clean-up settings are in place.
