The telco called and they said that it did report 1.9GB and it is due to Google services. But they are not able to offer anything concrete beyond that. They asked me to kill the app that run background to prevent refreshing (my life cannot be more busy trying to do this "killing app" things!). They also advise me to close all Safari session, suggesting that some websites that I had visited is/are trying to reload itself or something like. But even so, is it possible to hit 1.9GB just by one Safari app in one hour (32MB/minute?). Even if what they said is true, then why only occur within that 1 hour. Should it continue to 2.9GB, 3.9Gb and so on?
I just cannot convince myself that in a high tech world we live today, they have no clue about this. They told me that they cannot track down to the app level is due to privacy issue. So I told them I can give them 100% permission and I will not take legal action against them but they refuse to answer me directly.
I pray that there will be an app that can track, report, alert, limit data usage for mobile phone user, so as to better protect the user community instead of being "bullied" by the "BIG strong organisations".
Lawrence, thanks for follow up with this issue. The number (1.9GB) is confirmed by the telco. The date/time they reported is the time where I was attending a wedding lunch at the hotel. I was on 4G but was busy with friends and relative that I do not think I am using the phone except taking selfie and the famous WhatsApp app to sharing photos. I called Uber after the wedding which is outside the one hour window.
