using an unlocked phone from another network

[Fleshy]

I had my Galaxy S10 phone stolen, so i am now using my wifes Galaxy S8 which has been unlocked from EE, I can use the phone to make calls and use the apps when using wifi, however, I can't seem to use my data to access apps when not connected to wifi ... i have followed the instructions on My O2 to connect to the mobile networks, rebooted the phone, taken the sim card out and it still won't let me use anything unless connected to wifi, any help would be greatly appreciated

@Fleshy Did you report the stolen phone to O2? https://community.o2.co.uk/t5/How-to-Guides/Lost-or-Stolen-O2-Device-How-to-Report-it/ba-p/1023988

If you were issued with a new sim you need to speak to customer service to make sure all your service is reconnected. Below is the advice from an O2 Guru on how to get through.
Call 202 from your mobile.
When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.

Other numbers are here: Guide: Coronavirus Community Help and Support Use the Lost/Stolen option to get through. Otherwise you'll just be disconnected.

thanks it's all sorted now .... because the phone (and sim) had been stolen they'd put a bar on the sim but didn't lift it, its now been lifted and all is in working order, many thanks for your help xx
