Sudden data usage

[Anonymous]

Got text today saying I'd used 80% of my data allowance. I don't usually use more than 20% in a month - but right now I'm
Only 10 days in to my month.

I'm rarely not in wifi areas, I don't have wifi assist switched on, I don't have wifi/4g calling activated, I have switched off data use for non-essential apps and my iPhone data usage hasn't increased dramatically since a week ago when my flat mate had the same problem and I looked at it.

Has anyone else had this issue? Is there something wrong with O2 as I'm now the third person I know who has had this happen to them unexpectedly.

Thanks.

There used to be a problem with this on O2 and I actually moved one account to EE because of it, but we've not really heard much in the way of issues for a couple of years.
It was a problem that appeared to coincide with iOS7 introduction originally.
All I can suggest is that you call customer services and see if they can offer any help http://www.o2.co.uk/contactus

Hey @Anonymous did you manage to find out what happened with your data allowance this month?

Hi Martin - no haven't found a reason for why this has happened and had a colleague at work tell me the exact same thing also happened to her last week. We've compared apps to see if we have the same one causing the issue but no. Out of the now 4 people I know that have had this issue in the last week, none our iPhones have registered a spike in mobile data use although O2 says we have used almost a gigabyte of data. I really think this must be an issue at your end and it's worrying me! Im nervous to use mobile data on my phone now in case it suddenly drops again - I've got mobile data switched off now.

We've had another report of this tonight too.

I have had this exact same problem this month - I've had to buy an extra 1.5gb of data to get through the remainder of the month.

I've never gone over my 3gb allowance - and I'm around 70% through a 24-month contract. My average is 2.3gb

I've contacted the live chat but I've had some very vague information 'that someone is looking into it and will get back to you within five days'.

Is this affecting a siginifcant number of people? From the replies above, it does sound like it might be...

The second live chat I had suggested - again, quite vaguely, that there were technical issues affecting a number of users.

Would appreciate an update please, if only to say that there is an issue - I work during my commute and I need to rely on data availability.

Thanks - 

Chris
