Hi @t.hamilton20 

Just to confirm, is your phone up to date?

The new APN settings are the same as the ones in the article here https://www.koodomobile.com/en/help/picturemessagingchanges?

I’m having the same issue on my OnePlus  Nord N100.  Running Android 11, last security patch that’s supported by OnePlus is October 5, 2023.   APN settings are up-to-date. I reached out to OnePlus and they said they believed it was a carrier issue.

There were two discussions here regarding the settings for OnePlus devices, this might be of  help for you too:

Yes the APN settings are the same as the ones in the article.

After trying several things, finally got it to work. I had to delete the old APN and only have one APN profile. After deleting the other one and restarting, MMS started working again.

Same here.  Not sure what changed, but all the same settings somehow appear to work again. 

All that link tells me is I have to buy a KoDoo after having just bought a phone, No, I wouldn’t buy a stalker, and now told to to buiy another one because KoDoo decided to turn their back on existing customers, or buy KoDoo.

The real settings (free to read so far) is at https://www.koodomobile.com/en/help/setting-data-your-non-koodo-phone

Did you follow the same steps as mentioned above and delete the old APN settings on your phone?

Yes. But what I finally noticed is, that I used KoDoo instead of KooDo.

Koodo will just have to change it’s name :)

I have had the same SMS/MMS issue for the past several weeks (as of this writing, April 3, 2024).

I believe I have resolved it today, echoing what t.hamilton20 and MilkyWay have indicated: ensure you delete the old APN profiles - especially if the APN is actually still referenced as ‘sp.koodo.com’ (despite whatever nickname you are giving the new profile, and despite if the new profile is clearly ‘selected’).  Once I deleted older profiles with the APN ‘sp.koodo.com’, my SMS/MMS functions have appear to have returned -- can send longer-than-160 character messages, as well as attachments (i.e. photos, jpeg images, .txt files, etc.).  The text messaging program I am using is Fossify Messages, version 1.0.1 as obtained from the F-Droid  store.  I de-activated the stock Messaging program, thinking it was an app issue -- I have yet to re-activate it to see if it works.

It just seems that larger files take longer to transmit.  I tested this between my mobile, a VollaPhone lfrom Germany] running an Android 12-based AOSP operating system, and a iPhone 12 from work.  Also managed to send three photos from the iPhone to the VollaPhone, so I know that it works both ways now.

There is another (older) APN profile still in the settings, but under ‘sp.telus.com’, and it doesn’t appear that I needed to delete it.  I did not have to restart the mobile after deleting the older APN ‘sp.koodo.com’ profiles for the SMS/MMS functionality to return, but your phone might be different.

Based on another thread, before doing the above, I did try switching between the 4G/LTE and 3G network choices, and doing a soft re-boot, but that didn’t do anything.

Hope this helps everyone.
