+MCSN, Motorola Change Subscriber Number

This AT command sets EFmsisdn in the SIM. The setting is placed in the given <index>, using <number> and <alpha> as the values to be set.

Additionally, when setting the number in a specific storage space, the <mode> parameter defines whether that <number> and corresponding <alpha>should be presented after entering the correct PIN number.

After entering the correct PIN number, the last <index>, whose <mode> was set to 1, is sent to the DTE. This indication is unsolicited and appears when SIM information is ready.

Note: At any given time, only one <index> or no <index> can have <mode> = 1. Therefore, setting <mode> = 1 for one of the supported <index>es implicitly means that all other <index>es have <mode> = 0.

Set Command

The Set command sets EFmsisdn in the SIM. The setting is placed in the given <index>, using <number> and <alpha> as the values to be set.

If only the <mode> value is given, then the Set command is interpreted as follows:
