Cannot change address in app

Change your contact details directly in the customer portal under *My Details*; you can save them there.

I tried several times, waited about 2 days, but I kept getting the same address.

Where did you try that? It only works in the customer portal!

So which one should I change then, billing address or contact information? Because I tried both and nothing changed for me.

Hello ​@Geles2026,

welcome to our o2 Comunity 🙂

Did you try to change your data via the customer portal? 

If it is not changing there, you can try a different browser.

Best Regards,

Gerrit
