Can I use my data on 2nd phone

[Michael-]

I have 2 iPhones, 1 is bt that contract has just finished and my other contract is with o2, I have been with o2 for years and was wandering if I could keep my same number and use my o2 data and calls on my other phone once I get a chip and 02 unlock it. My wife uses the other phone so it would be like sharing the contract. TIA

@Michael- 

You can only have one number per sim so it's not possible to use the same contract in two phones.

If you want the old BT phone to use on O2 you would need to ask BT to unlock it, get your PAC from them Guide: How to get your PAC [June 2021 Update]  and then purchase a sim only from O2 https://www.o2.co.uk/shop/sim-cards/sim-only-deals#deviceType=phone&contractLength=Featured and port your number across https://www.o2.co.uk/help/device-and-sim-support/how-to-keep-your-mobile-number , but it will be a second account with O2
