Modems
Configuration
This page lists all available WWAN modems. They can be disabled on demand.
Query
This page allows you to send Hayes AT commands to the modem. Besides the 3GPP-conforming AT
command-set, further modem-specific commands can be applied (can be provided on demand). Some
modems also support running Unstructured Supplementary Service Data (USSD) requests, e.g. for
querying the available balance of a prepaid account.
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.
Configuration
A SIM card is generally assigned to a default modem but this may switch, for instance if you set up two
WWAN interfaces with one modem but different SIM cards. Close attention has to be paid when other
services (such as SMS or Voice) are operating on that modem as a SIM switch will affect their operation.
