What happens to SIM cards that send no data/are inactive for longer periods of time?
For SIM cards that do not transmit any data for several months, it can be assumed that either the SIM card is defective or the connected device is defective or destroyed. To release the reserved resources from the SIM card, SIM cards that have not transmitted any data for 18 months consecutively are automatically deactivated.
