sammie i hope you're not trying to send mms to the UK cause it won't work!!

as for GPRS i believe if you're using a prepaid line you won't be able to access POP3/VPN email accounts. I think you might need to get a postpaid line and subscribe to Mobinet (20 QR a month and you get 10 MB free).

In any case you may need to upgrade your phone or add some form of patch to the software. sometimes taht's just the problem.
