Figure 5.10.: SIMs
The SIM page gives an overview about the available SIM cards, their assigned modems
and the current state. Once a SIM card has been inserted, assigned to a modem and
successfully unlocked, the card should remain in state
ready
and the network registration
status should have turned to
registered
. If not, please double-check your PIN.
Please keep in mind that registering to a network usually takes some time and depends
on signal strength and possible radio interferences. You may hit the
Update
button
at any time in order to restart PIN unlocking and trigger another network registration
attempt.
Under some circumstances (e.g. in case the modem flaps between base stations) it
might be necessary to set a specific service type or assign a fixed operator. The list
of operators around can be obtained by initiating a network scan (may take up to 60
seconds). Further details can be retrieved by querying the modem directly, a set of
suitable commands can be provided on request.
