If there is no mobile coverage where you are, the router cannot connect to the internet, even if the SIM card and data plan are active.
The router’s Wi-Fi may still be visible and you are connected to the router, but you get no internet connection because the router has no contact with the mobile network.
It is best to move the router to another spot, for example closer to a window or higher up. You can also try manual network selection to see whether another operator has better coverage in the area.
If you are on the move, the connection can come back automatically as soon as you reach an area with better coverage.
Placement can make a big difference
Try the router in several places, preferably in the open and near a window. The motorhome’s metal body, insulation and other obstacles can weaken the radio signal. Just a few metres away, the router may use a different frequency or a different mast and give a noticeably better result.
What affects speed
Mobile speed does not only depend on whether the display says 4G or 5G. Distance to the mast, frequency band, obstacles, network load, placement and the operator used can make a big difference. So a stable 4G network can sometimes give a better result than a weak 5G network.
