Here's my problem.
I'm on the O2 network. Problem is, I'm in the Netherlands. So I'm not sure whether the O2 listed is just the British part of O2 or the entire network. I have tried it, as well as selecting 'other'. I've also tried my number as 00316...etc. and as +316.... In the Netherlands, all phone numbers are 10 digits and mobile numbers start with 06. So for the international access code you have to dial +(abroad)31(accesscode Netherlands)6(mobilenumber) and then the rest.
Can anyone point out to me why it doesn't work and secondly if it's possible to get it to work at all? =/
Thanks in advance!
