No MMS sending and no APN editing My APN settings aren’t there, there is no option. I’ve tried using the ID Mobile phone setting sender but it doesn’t work for an iPhone 6 whether I send with or without APN. My OH also switched to ID around the same time I did. He has just done a test for me and could send MMS via non-iMessage, so I’ve compared the settings, and found that he had (Under Settings-General-Mobile Data) - mobile data turned on, mobile data roaming turned off. I had mobile data roaming turned on, and enabled 4G (for voice and data) and enabled roaming. I tried matching the settings but it didn’t seem to work. I believe ID Mobile piggy back off the Three network. I have a spare android phone on the O2 network and I appear to be able to send MMS to that number, however I can’t send to my friend, (who I think is on EE, awaiting confirmation). Perhaps it is something to do with the phone my friend has rather than the network - I shall continue testing with other friends. So, so far: O2 - :ballot_box_with_check:
