-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)SIMcardcontains ECC file, the numbers in ECC file can also be regarded as ECC numbers.
