MOTOROLA V 300 MMS SETTINGS

[Guest DRIVER1701]

I HAVE BEEN BROUGHT THE V 300 BUT IT IS ON THE T-MOBILE NETWORK. I WANT TO SWOP IT TO THE VODAPHONE NETWORK AND HAVE BEEN TOLD TO ENTER THE MMS SETTINGS. VODAPHONE CAN NOT HELP BECAUSE THE PHONE IS NOT ONE OF THEIRS. I OBTAINED A CODE TO ALLOW ME TO PUT MY SIM CARD IN AND USE IT BUT ALL THE SETTINGS ARE STILL T-MOBILE.

:) CAN ANYONE PLEASE HELP???????????????
