Spitz AX (X3000) sending USSD-codes for activate SMS text service

Hi together

I got one router (Spitz AX / X3000). I use it with a multi SIM card.
If I like to activate SMS / text messages with my SIM card, my telco provider
expect the following command: 222#.
But this does not work with the Spit AX. Sure, I can send Manual commands
linke

AT+CUSD=1,"*222#",15 or AT+CUSD=1,"*222#",15

But this does not work.

I like to set this parameter from remote PC, because the router itself is mounted at the roof of my building.

Any ideas?

Thank you.
