I have changed the SIM. Do I need to restart the router?

Yes, we recommend restarting the router after changing the SIM card.

When it restarts, the router reads the new SIM card and tries to register on the mobile network with the right settings.

It is best to switch off the router before changing the SIM card. Insert the new card correctly, start the router again and wait a minute or a few minutes while it searches for a network.

If you use a roaming SIM, also check that data roaming is switched on.

With SIM problems

It is best to switch off the router before taking out or inserting the SIM card. Check that the card is the right way round and fully inserted. After changing the SIM, the router should be restarted so that the modem registers on the mobile network again.

Check the SIM card systematically

With problems with a physical SIM card, it helps to separate the card from the router. If possible, test the SIM card in a phone with mobile data and roaming switched on and Wi-Fi switched off. If the internet works there, you know that the SIM card and the service basically work.
