No network with Germany SIM fault?

DeutschlandSIM may currently have a problem, which is why you currently have no network:

On the Allestoerungen.de page you can see if there are currently any problems with the DeutschlandSIM network.
If there are several messages about a missing network, you can already rule out that the fault is yours.
In this case you have to wait until the network is working again.
However, if there are no messages, we recommend that you contact support.

First, try restarting your smartphone. Most of the problems can be solved in the simplest way.
If you still don't have a network afterwards, make sure you are in an area covered by DeutschlandSIM.
If you have another device available, you can test there whether you have a network. If this is the case, incorrect configurations on the other device may be the cause.
If you do not have a network on the other device, remove the SIM card and check it for dirt or damage. The former can be eliminated with a microfiber cloth, for example.
However, if the SIM card is damaged, you need to contact DeutschlandSIM to get a new card.
