MMS messages
MMS messages are similar to text messages but also allow you
to attach multimedia files such as pictures, audio or video clips.
Each MMS message can be up to 300 KB in size.
Note: You need to set up an MMS profile before you can send MMS
messages. Normally, your smartphone will set up the profile for you
based on information retrieved from your provider.
Tip: Ask your network provider for the necessary information if you
need to manually set up the MMS profile.
