Mobile phone (Illogan Highway TR15)

Hi I'm desperately in need of a working mobile phone,doesn't matter what network as long as it can get internet etc,due to declining health I'm having to spend a lot of time in bed and it would be really nice to keep in touch with friends as well as relieving my boredom and to play games etc ,if anyone can help I would be eternally grateful,I know it's a big ask ,thank you for taking the time to listen
