My Plusnet login problems

[#1]

I've had a Plusnet mobile sim for some time. I never registered an online, My Plusnet, account for my mobile sim. I would now like to register an account but can no longer find any welcome letter or even remember the email address used, if in fact there was one. All I have is the mobile phone number and the texts I receive for the direct debit notifications. Please can you advise how I can now register a My Plusnet account?

Thank you in advance for any assistance you can give.

Try using the forgot password tool https://www.plus.net/my-account/mobile/forgot-password to create a new password although if you can’t remember which email address you used you may have to call 500 from your Plusnet mobile sim to find out.

I'd call Plusnet on 0800 432 0200, and speak to a human being
