all electronic devices with a flash memory have a limited lifetime. However to reach that on a GSM SIM card is nearly impossible. We have 10 year + SIM here at work which are used for device end-test (so they are switched on and off many times per day) and all are still working - despite the plastic is wearing out of course...
