Hi Nico1,
I’m on Optus now due to the Telstra issues I mentioned above. (Actually, circles.life, which uses the Optus network).
Some of these are from memory, as I had to put the sim back into an old Android, too many issues with the L5 for now.
Step 1: choose the “yesinternet” APN, disable WiFi, and confirm you can access the internet, like through a web browser.
Step 2: manually create a new APN, called “Optus MMS” or similar. Enter as many details as possible from nscomputing’s post above, but note most don’t get entered when adding a new APN. From memory, the APN is actually the only one needed.
Step 3: open chatty, the SMS/MMS app, open Preferences from the 3-line menu, open “SMS and MMS Settings”, then enter:
Step 4: now here’s the catch, you can only have mobile internet or MMS messages at once, due to a (hopefully temporary!!!) restriction on the L5. To get MMS messages, go back to the APN screen and select the APN you created in Step 2. Then you should be able to send MMSs, and receive any sent to you.
So how to do you know when you have received an MMS? Run the following command, and if anything appears beyond the “mms” file, you have a message to download:
ls .mms/modemmanager/
I was writing a script that would automatically notify you, but that is on hold until I go back to using the L5 with the sim.
Let me know if you have any questions.
