Apparently after Feb 7 Koodo changed some things that wouldn’t allow me to send MMS messages. I followed the steps listed below and it still didn’t work. No suggestions on the koodo forum worked either.

As if a stroke of luck I figured it out for my phone (CAT S42) which is an android. If you haven’t been able to fix on your phone using these this is what I did.
Reset network settings.
Then follow steps on the link above… BUT instead of creating a new APN just go into the default one and change everything so it has the matching info from the link above.
