You can swap out your sim card and continue to use most features of Smart24. Swapping out your sim card does not change your 'tracker ID', which is a device identifier, not a sim card identifier.
Caution: It's important to note that some of new features of Smart24 will require us to verify your phone number. So if you change sim card, you'll need to re-verify your phone number to continue to use these features. One such feature is SMS Fallback.
