MMS is not working for international texting while my plan includes it ...

[Winter_Squall]

I understand there was changes made back in late Feb causing a number of Oneplus phones to stop being able to use MMS due to APN changes. I have a 12R, newest phone and MMS works fine for Canadian carriers but I am unable to send pictures via MMS to contacts in the US. Anyone else having issues with International MMS messaging?

Ok, I have my fix. Confirmed to work both domestically and internationally, I had to delete the APN "Mobile Internet" altogether and recreate with the valued I show in my original post and restart the phone. I had also capitalized the SP.MB.COM as well but not sure it is required. Thanks all for the tips and thoughts, glad to have it working, ended up missing some important texts earlier in the week from a US parter.

@Winter_Squall   I don't recall exactly but a search brought up a thread where @yow613  said "replacing APN with SP.MB.COM" worked.

Fascinating, there are a lot of posts about this issue, do you recall offhand which portions needed to be capitalized? I can confirm at least two Oneplus phones, one new and one older model (8T), stopped working. Was there ever an explanation of this behaviour? APN settings coming from Oneplus or the carrier? I understand those that moved to other carriers did not have the MMS problem. My specific issue on international MMS hasn't been singled out so not sure if this is a net new issue or a continuation of one.

@Winter_Squall   Others here with OnePlus have had to put part of the APN into all upper case to get MMS to work properly.  Not sure if theirs was discriminating between Canada and US though.

@Winter_Squall 

your APN is correct.  But since it does not work, there might be a bit more work then simply updating.  Many confirmed that you need to delete the current APN profile first.  Then Add new profile and add according to this, please note case-sensivitve and do not add extra spaces.  Remember to save the new APN and then reboot the phone before you try

if that does not work still, please open ticket with PM support:
