After each code which takes effect in the net (all codes without
*#06# =IMEI(serial)nubmer) you have to press the green receiver-key.
Without this a change takes no effect! (here symbolized with the "@")!!


Write your numbers in memory and for call divertion as shown in the following example.
It protects you from problems. The +49 will be sorted out in your own country automatically):


+xy abc 0123456, where:


+xy international area code
(in Germany e.g. +49 instead of 0049)(the "+" is part of it!)


abc area code without zero
(for Dortmund e.g. 231 instead of 0231)


0123456 normal local-number of your call partner
is.
This all works in Germany. For your own country ask your local service provider.
