@AJC22: Can you try swiping up from your Home screen and heading to Settings > General management > Reset > Reset network settings > Reset settings, to see if this helps? Please be aware that this will also reset your Wi-Fi and Bluetooth settings, so you will be required to re-register any Wi-Fi routers or Bluetooth devices that you had previously added to your device.
If the issue persists, try enabling Mobile Data next time you attempt to send an MMS message, to see if this makes a difference.
