F..... Cellphone!

[Knut]

When I start the car, the display shown " Insert sim card! ".
The card is in its slot, but I still get the message.

Pulling the sim card in and out does not do the trick.
Anyone knows a better and a solution that might work?

If I take it to the dealer they will "try and see" on my expenses so I rather try this forum first.
