Troubleshooting
48
The module(s) cannot be
dialled in, but they seem
to have reception
because they have signal
strength (see chapter
Device operation and
operation
The signal strength
indicator shows neither
Home nor Roaming (see
chapter Dial-up settings).
Possibly the modules see
generally available
mobile radio networks,
but could not register in
these.
Make sure
→ that the data-enabled
SIM cards are inserted
correctly (see chapter ),
→ that the SIM cards
may not require a SIM
PIN, but this is not
correctly configured.
→ that the router has
been restarted
after inserting the SIM
cards or reconfiguring
the SIM PIN settings, see
chapter SIM card holder
in router housing
