A bitfield describing the specific access modes and technologies supported by a device and the access technology in-use when connected to a mobile network. Unknown or invalid mode. For certain operations, allow the modem to pick any available mode. GPRS EDGE UMTS (3G) HSDPA (3G) Prefer 2G (GPRS or EDGE) Prefer 3G (UMTS/HSDPA/HSUPA/HSPA) Use only 2G (GPRS or EDGE) Use only 3G (UMTS/HSDPA/HSUPA/HSPA) HSUPA (3G) HSPA (3G) GSM GSM Compact A bitfield describing the specific radio bands supported by the device and the radio bands the device is allowed to use when connecting to a mobile network. Unknown or invalid band For certain operations, allow the modem to select a band automatically.

The facilities include the personalizations (device locks) described in 3GPP spec TS 22.022, and the PIN and PIN2 locks, which are SIM locks. No facility SIM lock Fixed dialing (PIN2) SIM lock Device is locked to a specific SIM Device is locked to first SIM inserted Network personalization Network subset personalization Service provider personalization Corporate personalization
