I'm getting the same problem, I can't send texts at all. I am on a contract. I have recently moved over to ID. It's really frustrating. I would like to know if there are any issues and when they will be resolved. It looks like it happens a lot. I wish I'd stayed with sky mobile
I'm on a Sim Only contract but I've got the same problem too. Must say I've been with them for about 4/5 years now and never had any problems prior to this. Assuming it's a network issue but it is sooo frustrating that there is no information to show there is an issue and also that proper live chat doesn't exist!!!
