8.8.2Service states

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.
