Having a problem sending MMS messages on my Huawei P20 Pro and hoping someone may know of a hidden menu that I might need to adjust.
My phone is on Giffgaff, runs on O2 network, and I have checked the APN settings, replaced the Sim, and have credit that should enable me to send MMS messages. I have tried a different phone and still cant send MMS messages.
I can receive messages ok and did manage to send 2 messages last week , although they did take 3 hours to get through. The 2 that did get through were the same as 2 of the 3 that failed.
According to giffgaff the problem is my phone or my APN settings which I dont understand as 2 did get through.

Any help or advice gratefully received as I'm pulling what little hair I have out.

I know I could use something like WhatsApp but I just find MMS easier.

Thanks
