--------Thanks.

You should try making sure you're on a blackberry mobile plan with your network because certain plans get certain privileges. Try looking up the wap(not sure) and switch the Place where you send and receive data

This could only be caused by a couple of things. The message center number in the handset may not be correct, which will cause the messages to fail. The other possibility is that the feature is not active on your account with your wireless provider. What you need to do is test a couple of things. See if you can send a text/sms message to yourself, in doing this you can verify that you can not only send, but receive text/sms messages. If you cannot send, or receive text/sms messages, then that verifies that the message/service center number is off, and will need to be corrected. If that works, and you can receive text/sms messages, then your service center number is correct, and you will move to the next troubleshooting step, which is to test your web browser. If you cannot launch the web browser on your handset, then this is an issue, because the MMS service requires that you have both SMS, and web browser service to send a MMS message. If you can access the internet and you have the ability to send/receive text/sms, then you need to call your service provider as the issue may be with their service.

bluetooth and mms does not work at all

You have to have the MMS service activated on your number as it is an additional expanse it is offered separately.

MMS is sending a file.. not not necessarily a file.. but pics, videos, etc. ...

SMS.. is Short Message Service.. used for texting.. some texts can go as far as 190 charactars [that also goes with letters] rate if useful please !

last time i had to do this i rang up my service provider eg (optus or telstra etc) n tell them u want to enable MMS settings...they'll ask u what modle phone u have etc then they should sms a link to ur phone...u open it and save it and u should be able to send mms...i think their called WAP settings

You need to make the request for these from your network provider -Who will most likely send them via SMS which you need to save.

The settings are all different, Internet, Wap etc... for MMS you need to call your service provider and ask them to send you the MMS settings, they are sent via a txt msg, when you receive them click Save or Install.
MMS doesn't work between all networks.
