Cannot send MMS

[samc888]

I have an iPhone X and for some reason I cannot send MMS but I am able to receive. Just cant send. Anyone know what could be wrong? or can direct me how to fix this? I did change the APN as directed on the set up. But I dont see anywhere to change the MMSC and MMS Proxy thats also on the tutorial. All I see under APN is Username and Password which are blank but other than that theres no area or anything about MMSC and MMS Proxy settings on my phone.

1. From the home screen navigate to Settings>General>Reset
2. Tap Reset Network Settings
If prompted enter your passcode
3. Tap Reset Network Settings
4. Restart your phone

@samc888 Hi all you should need to do is enable your data make sure it is on there should be no reason to change your settings especially in an iPhone X

@samc888 enable sms and mms under your Imessage settings. Stay safe.
