Can’t use internet or send texts on my new phone outside of my house

[Tzoid]

I have just bought a new phone and SIM card, whilst using my phone at home everything works as it should when I’m outside I can’t use my data or even send texts or use any internet

This isnt live chat or Customer services, but a customer to customer forum... 

Was this an upgrade or a new contract. 

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. if you send them a message on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG), or you can call 202 from your o2 phone
Thanks

If you upgraded you can use your old sim card or do a sim swap to activate the new sim.
