yeah my wee bro is in germany and has a german mobile number, its cheaper that way, Im going away next month to NEw Zealand and will buy a local sim to use whilst away, seems like a brill idea to me
"NO, mobile phone numbers don't use country codes. "
Dunno where you get that idea from; if you wanted to call me on my mobile in Greece, you would need to use the +30 prefix exactly as you would for my landline, and conversely, if I was going to dial your UK mobile, I would need to use the +44 prefix.
