Oh I didn't realise the original poster's messages were actually
sending. Mine fail instantly & don't get sent at all even after having a
new sim. Must be a different issue.
Hi, I've been having this issue since I've joined o2 earlier this month.
Is there any workaround? I don't seem to be able to send texts without
them failing 5 times first. Also on iPhone 14 plus on ios 16.
