Network problems? I think!

[Newbea]

I have a s5 and am with 2 degrees. There is signal but in the notification panel, it says the selected network is unavailable.. i can't send or recieve phone calls or sms messages. When I try, it says I'm not registered with a network and when I go to my network settings and select the 2 degrees network operator it says I'm registered with the network..please helllllp!

Has it previously worked on 2Degrees?

Is it possible that the phone is SIM-locked?

Have you tried in a different area - one tower may be down or something?
