At Commands Description - Sierra Wireless AirPrime WS Series At Command Manual

1. AT Commands Description

This manual presents detailed information about the AT command set used with the AirPrime WS
Series of Intelligent Embedded Modules including WISMO218 and WISMO228.
Note: There is no SIM card auto-detect mechanism for the AirPrime WS Series of embedded modules. After
the SIM card has been changed, the embedded module has to be restarted in order to detect the new
SIM card. If the SIM card is not detected by the embedded module, most of the AT Commands will
return ERROR.
