Hello @benmuchenje ,
Welcome to the community,
If on contract, as @BrendonH , has mentioned, have you kept up with payments?
Is this just in one location or everywhere? If in one location, have you checked whether there is a problem where you are? You can do this here, report it and receive updates when you register:

Have you checked whether there is a problem with your SIM card or phone? Try a reboot, also check whether your phone is in flight mode, as that will stop you receiving and making calls.
More information might have helped to help you, as well.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
