Hi

You will need to connect to wifi to use data or get a local sim card if your iPad is unlocked.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion.
This is not Customer Service so we are unable to help with account specific issues.Currently using:
