Description: Get/set current GSM/UMTS network operator, list available operators. This can be used to change for example access type and switch network.

<mode>

0. Automatic network selection (<oper> ignored)
1. Manual network selection, <oper> must be present, <AcT> is optional.
2. Deregister from network.
3. Set <format only, no registration/deregistration.
4. Manual selection with automatic fall back (enters automatic mode if manual selection fails).

<format>

0. Long alphanumeric string
1. Short alphanumeric string
2. Numeric ID

<oper>
String (based on <format>) that identifies the operator.

<stat>

0. Unknown
1. Available
2. Current
3. Forbidden

<AcT> Network access type

0. GSM
1. Compact GSM
2. UTRAN
3. GSM with EGPRS
4. UTRAN with HSDPA
5. UTRAN with HSUPA
6. UTRAN with HSDPA and HSUPA

The following example shows that the devices is connected to the operator called “3″ using UTRAN (which is UMTS, also called 3G). Listing available networks shows the current network, an additional UTMS network called Sweden3G that is forbidden and a GSM network called “3″ that is available.

Example:

>AT+COPS?
+COPS: 0,0,”3″,2

AT+COPS=?
+COPS: (2,”3″,”3″,”24004″,2),(1,”3″,”3″,”24008″,0),(3,”Sweden 3G”,”Sweden3G”,”2)
