> 8.10.2 | 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 connectionestablished 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 reselection 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.
