Hmmm, that somehow even amcht the cell phone. That sets off always automatically ne 031 + 41 on the Rufnummmer....

Hello!

Always properly selected?

Only the phone number for the local call.
0 + xx + area code + phone number for long distance calls.
00 + xx + country code + area code + phone number for international calls.
(Area code/country code without 0)

XX stands for an Operador, e.g. 21 for Embratel.

Greeting
Thomas
