Issues mobile date and calls

[Bb8]

hi, I don't understand why I don't have internet and I can't use calls 

[gmarkj]

Could be a number of reasons @Bb8 

Are you on pay as you go (PAYG) or pay monthly (PM)?

If PAYG, do you have an active bundle or credit on your phone?

If PM, are your bills up to date?

For both, it could be there is a problem with your sim card.

See if any of these guides help, and if not please come back with some more information.

Guide: How can I sort out my network issues? 

Guide: Is the network down for me or everyone?

To add to the great advice given by @gmarkj, could I just add, if you have a sim problem, it's far simpler to go instore for a new one. Take ID and they will swap everything over for you.

Best of luck. x
