To be able to enjoy picture messaging and GPRS, you would need to have a mobile phone that supports GPRS/EDGE. If you already have such a phone, simply bring your phone to your nearest Incomm branch to get your phone configured.
Nokia and Sony Ericsson mobile phone owners can get GPRS/EDGE settings sent to their phones 'Over-The-Air' by accessing their respective websites. Simply click on their logos and you'll be re-directed to their support websites.
