Hi I’ve signed up to o2 open as I work for the nhs and I’ve entered my work email address. However I am not in work until next Friday now, does the link sent to the work email have an expiry or will it be okay to use after 7 days?
As long as you get to it and complete the registration inside 28 days, you'll be fine.
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.
