Can't seem to send images in text messages?

I have problems receiving mms. I can send them. Group sms also doesn't work. I've opened up a ticket.

You need data to send mms. Do you have data? Did you set APN for mms? Are you on Fizz carrier 34.1

First check your APN setting. You can also try to desable LTE for about 10 seconds and enable it back. This worked for me on my OnePlus 3.

Some people have found that their mms doesn't work if their WiFi is switched on, so that's another trick to try.

I had the issue over the weekend, and was able to resolve it with:

Specifically #8 and updating my SMSC with +14385200092

You need have mobile data option in order to send/receive MMS.
