Parameter
7.19. AT+QECCNUM Configure Emergency Call Numbers
The command can be used to query, add and delete ECC numbers (emergency call numbers). There are
two kinds of ECC numbers: ECC numbers without (U)SIM and ECC numbers with (U)SIM. The default
ECC numbers without SIM is 911, 112, 00, 08, 110, 999, 118 and 119. The default ECC number with
(U)SIM is 911 and 112. 911 and 112 will always be supported as ECC numbers, and cannot be deleted.
ECC numbers can be saved into NV automatically. If the (U)SIM card contains ECC file, the numbers in
ECC file can also be regarded as ECC numbers.
The maximal supported ECC numbers of each type is 20.
