I have put a SIM-card into the FP2, that was not yet registered by the provider. It showed “Netz” (Net) as provider and no number. After registration the cards works, phone-calls in and out and data is fine, but the settings still show do not show network/provider and number:
I tried to reboot, took the card out, even replaced it temporarily with another SIM, but it does not help- The FP2 has cached the false infomation.
So how can I get the FP2 to rescan the SIM or clear the cache.
