My phone is not receiving calls or texts from anyone, I can make calls but not send texts.

Sounds like something you need to speak to o2 about, all the contact details are here Guide: How to find help & contact O2

Check for any local mast issues, @Brian914 -

Guide: Is the network down for me or everyone? 

And if there is a disruption to your O2 service, try disabling WiFi calling on your handset to see if you can get enough signal from another nearby mast for your SMS to send and receive successfully.
