I'm using Nokia 6230. Here's the MMS setup. For other phones, just use the right brand/model combo.
1. Send request sms -
message: mms nokia 6230
number: 6827
2. Confirmation message will be sent to you saying that tehy got your request.
3. Activation message comes to you a few minutes later. Save it, entering following -
PIN: 1234
4. Go to MENU>SETTINGS>CONNECTIVITY>GPRS
Select: Always on (no, it will not run up your bill)
5. Go to MENU>MESSAGES>>MESAGE SETTINGS>MULTIMEDIA SETTINGS>CONNECTION SETTINGS>ACTIVE MULTIMEDIA SETTINGS
Select: TSTTMMS
That's all. You'd now see a "G" icon at top left of screen.
6. To send multimedia message:
Go to MENU>MESSAGES>MULTIMEDIA MESSAGES>CREATE MESSAGE
Type your text, then select OPTIONS>INSERT. Now select your picture, movie or sound. Select OPTIONS>INSERT.
Press send when u finished, type the person's tele number.
NOTE: The number must be in full 11digit format and prepended by the plus sign. eg: +18681234567
MMS messages cost 60cents for postpaid and (i think) $1 for prepaid.
*If there's any hot, smart chicks that get this to work... send me your pic
