I went on holiday to Switzerland in 2018 and was hit by a lot of charges; no issue there I hadn't done my research properly. So on going again this year I was careful not to use my phone, other than the pedometer I have on it as we do a lot of walking. Anyway, having returned home I see I have now incurred charges of £43.67 having (supposedly) used the internet 166 times!! These include charges at 00:00. 01:00. 02:00 etc when I would have been fast asleep! Many of the others are at set times per hour, generally XX.54 or XX.55.
Also, whilst there, I received a text from Virgin Media telling me I was nearly at my £51.50 data limit. If I have such a limit then why am I being told I have run up a bill which is less than that?
I just switched off the phone at the side and occasionally switched it on and off again. I guess I should have powered it off completely, but of course had I done that I wouldn't have been able to use the pedometer, which I was anxious to do.
Clearly I have misunderstood all the terms and conditions, but seeing I never sent any picture messages, or never made or received any calls or voicemails, and never Googled any websites, it's disappointing to receive a bill in excess of £43 for basically doing nothing.
If you don’t need to stay on top of your emails, while you’re away, it makes sense to switch off data roaming. That way your phone won’t be quietly using the internet to automatically update itself and building you a bigger bill. Most phones love connecting to the web, and they’ll be doing that to update your phone’s software, or even location, without you necessarily knowing.
