I had the GX10, they are all Vodafone to start with and I changed mine to Orange..however, despite putting all the correct settings in and talking to Orange..these phone will txt and make calls but the mutlimedia functions won't work unless you are on Vodafone.
I had the same problem when I had my GX20 unlocked. I spent many an hour on the phone to Orange customer services but they didnt have a clue!
I worked out to send a picture message i have to press 'reply' on a previously received mms. This somehow sends my new picture back to the original sender! anyway it works for me. Downside is you have to get your mate to send you a pic first so you can reply to it.
