cannot send and download mms message

[jeffrayhuang]

Since I subscribed to public mobile from about a month ago, I was not able to send and download mms messages. Before I moved here, it was all fine with other carriers. I checked apn settings and it was correct. I also checked mms setting of my phone message app.

my phone is oneplus9.

Thanks, this fixed my Asus. It was working before, but I think the settings got nuked trying to fix roaming on my second carrier's sim with a network refresh.  (Dual-sim)  For some reason there were the Telus and Koodo APNs available as well after the new defaults came in.

Capitalization was the key! SP.MB.COM

I applied your settings and it works. I really appreciate your help.

With OnePlus, there might be a bit more work than simply Reset Network or updating APN.  Many confirmed that you need to delete the current APN profile first.  Then Add new profile and add according to this, please note case-sensitive and do not add extra spaces.  Remember to save the new APN and then reboot the phone before you try

I have seen some previous discussion about the APN settings not working on some devices unless the sp.mb.com is saved with that address in all capital letters.
