My iPhone 5 picture message failure

[Discomama]

Hi my iPhone 5 has suddenly started displaying message send failure when I try and send picture messages....have tried over wifi and to other iPhones and non iPhones, I haven't changed any settings, so why has it had such a strop??

Bastarding iPhone 5. It's probably doing it because it can. Just like mine spends most of the week with no reception at all.

use whatsapp instead...

My 4S used to have issues because the files were too large. I changed something in settings which let it send bigger ones.

General > Cellular Data > scroll down to MMS Max Message Size

Although I think mine claimed to have sent them, they just never arrived properly.

Alternatively, Settings > Messages > Scroll down to make sure MMS is switched on,
