• It's possible to apply a 5- or 6-digit LAI for numeric format of <oper> parameter. Please use the correct 2- or
3-digit Mobile Network Code. Otherwise an unintended PLMN could be selected.
• It is not recommended to use the AT+COPS write and test command while the device is searching for a new
operator. In this case the module will answer with ERROR. Please use AT+CREG to verify the network
registration status.
• This command is PIN protected.
• This command is supported in airplane mode.
8.3 AT^SOPS Extended Operator Selection
Description: AT^SOPS queries the present status of the Multi-Tech wireless modem’s network registration.
Since basic operator selection services are available with AT+COPS this command uses the
methods of the Enhanced Operator Name String (EONS) specification while handling operator
name strings. Additional EONS related information is available with AT^SIND.
AT^SOPS test command lists sets of five parameters, each representing an operator present in
the network.
A set consists of:
1. an integer indicating the availability of the operator,
2. specification of the source of the operator name <eonsOperator>,
3. operator name according to EONS Table,
4. Service Provider Name from the SIM Service Table and
5. numeric format representation of the operator.
Any of the parameters may be unavailable and will then be an empty field (,,).
The list of operators comes in the following order: Home network, networks referenced in SIM
and other networks.
After the operator list the Multi-Tech wireless modem returns lists of supported <mode>s and
<format>s. These lists are delimited from the operator list by two commas.
If the test command is used while an ongoing GPRS transfer, traffic will be interrupted for up to
one minute.
