Hey @Huoma !
Welcome to the Community. 
I'm sorry to hear that you're currently unable to use your service.
A few thing to consider:
- Has the service possibly be suspended for non-payment or because you've hit your credit limit?
- Did you try to remove the SIM card and re-enter it in the phone?
- Have you tried to insert the SIM card in another device to see if you get the same result?
Should none of these options do the trick, you can contact us and we'll be happy to take a look at what's going on.
