PrimeTel mobile call forwarding

As I am planning to travel very soon, I needed a way to forward all calls from my mobile to another number (which will take care of routing calls to my other number while I am abroad). Googling for PrimeTel mobile call forwarding I found this page in their FAQ, but it turned out to for landline services. No other pages in FAQ related to the problem I need to fix.

Few minutes on the phone with their operator and here are the instructions (assuming I need to redirect all incoming calls to 25666666):

To activate, dial the following from your mobile: *21*25666666*11#
To deactivate, dial the following form you mobile: ##21# (yes – double # in the begginning)

Keep in mind that call forwarding works only when redirecting to Cyprus mobile or landline numbers, no international redirects are allowed.

BTW, I am using PrimeTel mobile for few months now and I am pretty happy with everything, including 3G, nice web-portal to view call/sms/data logs, view/pay bills and so on.
