Possible data usage glitch?

AFJ — Wed, 22 May 2024 21:39:16 GMT

So I recently upgraded my sim only contract to a device and data plan, I did have 100GB data before and went down to 15GB data for my new contract. This is because I was never using more than 10GB per month, the extremely helpful advisor even assured me that amount of data was unnecessary. Even when I was with O2, I was paying for a stupid amount and only using less than 10GB. My data allowance resets 1st of every month so it’s been less than a month and apparently I have used all 15GB of data already. Sorry but how does that make any sense? My phone usage habits haven’t changed for the worst, infact I use my phone a lot less during the day because of my new job, no new apps, I close my apps too, like how on earth have I used all that data in less than a whole month when I have never used more than 10GB per month in my whole 7 years of using contracts… there must be some kind of glitch in the system or an error whilst transitioning my previous contract to my new one maybe? Random technical errors happened all the time in my old job it does happen. Has anyone else experienced this? Not to mention customer service has been so unhelpful and caused me loads of stress, just repeated the same thing and not actually listening to what I’m trying to say, live chat purposely taking ages to respond to my message. Not to mention because my data “ran out” my maps stopped working whilst I was driving in the middle of nowhere and I got lost for ages, wasted a load of petrol and missed loads of time on my partners birthday. What an absolute joke.

Hi @AFJ,

I'm sorry to hear about this. I don't think it's likely that we'll have incorrectly accounted for your data, but you may be able to check this from your phone. If on an Android, have a look in your settings for App data usage, you can set this to check against the date your allowances reset, and get an idea what has been mainly using the data.

For iPhones it's a little more awkward, but if your phone is new, hopefully you should be able to check Settings then mobile data, and find out how much particular apps have used. iPhones will list "current period" and you have to manually reset this, it doesn't automatically reset each month, so depending on how long you've had the new phone it may be more difficult to interpret this the longer you've actually using the phone, but hopefully you'll be able to find out which app is the culprit.

We have a range of short terms add ons that can hopefully help till your next bill cycle starts. You can find more info on the Add on section of the Three App.

Thanks,
Jonathan

Yes same thing happening to me and my sister. We’ve called it through to three who are apparently investigating. They’ve said no issues they know of yet both me and my sister have usages showing up at 4am each day. Even with our phones data is turned off during the night. It’s showing extremely large amounts of data being used at the same time each day.
If you look on your 3 app and see when the data is being used you might see a pattern on times large amounts are coming out like us.

I am having the same problem, I have turned my mobile data off but my data when checking has been used, doesn’t make any sense and at all. I never had this problem when I had a phone contract with three this has only been since I went to sim only!

I have had the same problem and the same useless response from Three and clearly do not take responsibility for a glitch when the data disappear disappears.I have had the same problem and the same useless response from three and clearly do not take responsibility for a glitch when the data disappears.In my case my data allows failed to reset so that the data I had used remain the same at the end of the month and did on the first date of the next month! They also tried to flannel me with saying that something was using the data and I needed to go to Apple to ask them where my data had disappeared to even though the data I had used out of my loans was the same on the day after the monthly reset as it was on the day before the monthly reset! What a con! I’m just getting a new contract with someone else will be leaving through as soon as I’ve got my new Simin

Sorry about that now pay for additional packages? There’s a real issue with your data and we are being mined for money for it. I am going elsewhere now
