Data usage

[Nick61]

I have been on a 5GB data package since joining O2 and on checking my usage for the last 2 years I saw I have regularly used less than 3GB each month so i decided to downgrade to a 3GB package. In my first month on the new deal I have used up all my data with 2 weeks still to go!! There has bene no material change in the way i use my phone and I have not been abroad. Has this happened to anyone else?

Check your app settings to see which app has used the data

Call 202 if your usage hasn't changed at all

I have the same issue with downsizing tariff.

I was on a 5GB per month tariff but only using average 600MB per month so changed this week to a 1GB tariff. Less than 6 days into the new tariff I have apparently already used all 1GB of this months allowance. Have checked settings on my phone and there is nothing different to pre-tariff change so can only assume either O2 have never been reporting correct monthly usage stats or I have suddenly started to use lots of data (which I am not!).
