8.9.2 Service 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.
