After my data usage had gone up I wasn't able to send/recieve messages or calls. I don't know if it's really about my data usage or something else that might be wrong, It's just says that I'm "Not registered on network" when I actually am. I have tried to shut on and off airplane mode. (which didn't work) When I added a contact I could choose between Connected via Device, Sim Card or Google. I tried all of them and couldn't contact with any.
My other apps still works with wifi.
