There's every chance that you won't be able to login to your MyO2 app as it requires a code to be sent to your phone.
If that's the case, try your MyO2 on the web or pop in store with photo ID.
We also recommend staying with a physical sim as esims create issues such as you are experiencing now.
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.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
