Note table 'siminfo' column 'icc_id' has been zero'd out by me.
Of the two entries, entry _id=2 has value for 'icc_id' equal to the ICCID found in Aboutdevice->Status->ICCID
Entry _id=1 may be my old sim info - not sure.
The apns listed in Access Point Names in Settings all have MCC=310 and MNC=120 which is what the siminfo entry has as well
