8.8.2 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 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.
