Hi @Luke2546
Welcome to the community.
Please try toggling 'Airplane Mode' on, then off again. It'll force your phone to search for a mobile network.
If you're still having problems, please check your postcode on our network status checker. It'll let you know if we're aware of any problems in your area, and let you report one if we're not.
Let us know how you're getting on please.
Chris
