Columns for Dedicated channel:

Depending on the service state, an additional textual output is generated (refer also to the response examples): 
• 'Searching' - The MS is searching, but could not (yet) find a suitable cell. This output appears after restart of

the MS or after loss of coverage. 

• 'No connection' - The MS is camping on a cell and registered to the network. The service state is 'idle', i.e.

there is no connection established or a dedicated channel in use. 

• 'Cell Reselection' - The MS has not yet lost coverage but is searching for a better cell, since the cell reselec-

tion criterion is fulfilled. 

• 'Limited Service' - The MS is camping on a cell but not registered to the network. Only emergency calls are

allowed. The MS enters this state, for example, when 
- no SIM card is inserted, or PIN has not been given, 
- neither Home PLMN nor any other allowed PLMN are found, 
- registration request was not answered or denied by the network (use command AT+CREG to query the

registration status), 

- authentication failed.
