I recently updated my 3G iPhone to use the 3.0 firmware. In doing this I knew that MMS would become available but I’d need to change a few network related settings.

This turned out to be a nightmare due to my network not providing any information on how to do this. So if you’re with 3 mobile in Australia and are having the same issue, here’s what you need to do:

1) First go to Settings > Phone and set your phone number. This needs to be in the following format:


If you add 01 or +, MMS will not work.

2) Visit Settings > General > Network > Cellular Data Network > MMS and enter the following:

APN: 3services
MMSC: mmsc.three.net.au:10021/mmsc
MMS Proxy:

Leave the other fields blank.

3) Finally, visit Settings > Messages > MMS Messaging and make sure this is set to ON.
