can receive, but can't send text messages on 02

[19Dave65]

Since December, I've been able to receive texts, but cannot send replies to them. There's no problem with calls. What is the cause of this, please. When I visited an O2 shop, the staff were very unhelpful.

Thanks,

David

If not, you may need to get a new sim and swap your details over: https://community.o2.co.uk/t5/How-to-Guides/SIM-Swap-a-mini-guide/ba-p/1060675
