Use Sim Card

Hello.
had installed a Becker Online Pro 7800 radio.
Since at every start of the radio the message
"Sim card is missing! " appears in the display, I thought
then we just put one in and try
I would like to thank the rapporteur for his excellent report.
Where do you put the Sim-Katre?
Any??? Is there a special place where ?
On the radio probably not,or ?I can't
and the

Happy feast to everyone.

Greetings Dietmar
