MMS stopped working for no reason

[lilfoxki]

I have a Galaxy Z Flip 3 5G and for some reason my MMS just completely stopped working for no reason. I've tried everything to get it to work again and nothing helps. I don't want to have to factory reset my phone to make it work again. 

Please help !!

If you haven't turned your phone off then on again this is the first thing to try. The next step is to Google this problem because you will get more answers. Then read up on clearing the apps cache. Read up because if you clear the wrong cache you will lose all your history of messaging and backing up messaging is messy.

I've already tried all of that
and still nothing has worked. I guess a trip to Samsung themselves might help?

If you are on Samsung MMS try switching to Google MMS on Play Store. This would mean you won't have access to your history. Samsung have loaded Google SMS on some models. By the way, you haven't changed phone providers? This can cause problems.

I switched to Google MMS to see if it would work and it doesn't. I haven't changed providers either

What's your provider? Issue only happen with MMS? SMS fine?

I assume you are using data (wifi turned off) and still having issue with mms, some things you can check;
1. Try this suggestion if you are using Telstra - https://mobilesupport.telstra.com.au/samsung/galaxy-z-fold3-5g-android-11-0/messaging-email/i-can-t-...
2. Or check your network APN, make sure all settings are correct. You can google what's the default value for MMS for your network or how to set it up manually.

I got in contact with my provider and they couldn't help, everything was fine on their end, I'm going to go to a samsung store tomorrow to see what they can do

I am having the exact same problem. Cannot send MMS using Samsung Messages or Google Messages. APN default made no difference. Factory reset made no difference. The sim in another phone works just fine.
