Preparation of SIM cards - preliminary consideration
Have your SIM cards ready now. It is recommended to define the
assignment of SIM card and module number in advance. In the plus version
with a total of two modules, module 1 is addressed approx. 30 seconds
before the second module and prepared for dial-in. With the trio version,
the whole thing takes 30 seconds longer.
If the modules are online, they are used for data transfer; however, as long
as connections are not terminated (e.g. due to poor signal quality), data
paths remain in operation.
For a VPN, for example, use a data connection that is not quite as fast, but
is all the more stable. This should be activated first. If you need the VPN
immediately after starting your PC, you should prefer it to an occasionally
faster, but fluctuating data connection.
We deliver the CAR-A-WAN.112 without the SIM pin set at the factory and
recommend deactivating the SIM pin query if only you have access to the
router and SIM cards.
Deactivating the SIM pin
Please deactivate the SIM pin of your SIM cards with the help of your
telephone. If this should not succeed (with some SIM cards this is the case),
then we must keep in mind that we have to the CAR-A-WAN.112 later, and
that the SIM cards must not be exchanged with each other if we do not
want the mobile phone operator to block the cards by mistake.
Please do not insert SIM cards yet!
