Can't log in to O2 APP - receiving error message (code 5)

[Anonymous]

I haven't been able to log in to the app for days. Everytime I try my user name and password I get a (code 5) error message on the screen. The user name and password work perfectly ok on my lap top and desk top.

I have reset the password twice and makes no difference.

The twitter team were useless.

The online chat person was not helpful

The help line shifted me between 3 different teams and none of them had a clue.

Hi

Maybe try deleting the App and Re Downloading it too.

It's been deleted and reinstalled 4 times now.

Let's hope Customer Services can help then.

If not you could Private Message one of the O2 site staff here whom I'm sure would take a look for you.

I am having the same issue on a Lumia 930 Windows Phone. All software is up to date, uninstalled and reinstalled the My O2 app. Username and password works with no issue on a browser, it's just an issue with app; error message code 5

This seems to be happening to quite a few people recently. I wonder if @Toby or @Anonymous have any news as to why this keeps happening and why people are getting the same error code 5? Toby said he would be looking into it?
