I can't update my address on My O2

[Invicta21]

Long story but I will try to be brief.
Used to have two phones, one private and one work phone.  The private phone used to be my personal phone.  When I finished work, most of my contacts knew my work phone, so I asked my firm for this number to be transferred to me personally and this was done (circa 2016).  As I no longer usedmy personal number, I removed the sim card and stopped using a second phone.
Unfortunately the My O2 account now shows one device and one sim card which is great and I had deleted the other device/sim card some years ago.  However, I now need to change address and email address and the security confirmation codes are being sent to the old personal phone number, not my current active phone number. What do I do?  How do I get customer support to change this?  Do I need to email anyone as there seems to be no online help desk or chat service.

You can do it yourself in My O2. It doesn't matter that the code is going to your old phone.

Use the website.

You need to go into MyO2  http://www.o2.co.uk/myo2

Along the top of the page you will see various headings. It's in the section BILLS AND CURRENT CHARGES. Drop down box will show "Change payment or address details" and payment details will allow you to change your bank details. O2 will send you a text to make sure it's you

However, if you can't get this far with the wrong number you need to contact O2.

Give O2 a call on 202  or 0344 809 0202.

Or you can message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG), hopefully they should be able to help.

Thanks for the response.  I am on a Pay as You Go tariff, so can't access under Bills and Current Charges as I don't have that.  Will try messaging them.

Many thanks again

Ok @Invicta21 It's completely different for PAYG. You wont have all that in My O2 as you say.

Call 4445 or 0344 809 0222. Info for social media contacts remains the same. 😉
