probeTelephonyExtended
Probes extended telephony characteristics from TelephonyManager.
Reports network/SIM MCC+MNC, voice network type, data enabled/state, call state, voice/SMS/data capability flags, carrier id/name (Android 9+), multi-SIM support and modem count (Android 11+), and whether the Type Allocation Code is readable or blocked.
Privacy: carrier and SIM operator codes are moderately identifying. All reads here are wrapped defensively; identifiers restricted by the platform surface as blocked/n/a rather than throwing. No READ_PHONE_STATE permission is used.
Return
