AC Question
Hi all,
I have the following problem. I'm on a business trip to the USA and phone charges while roaming are steep. That's why I made sure to disable mobile data in Settings to avoid paying for traffic. However, I got charged USD 30 anyway; my carrier explained to me that I've used mobile data on several different days and that it's probably due to some background tasks.
I find that hard to believe though. As I said, mobile data has been disabled globally the entire time and I see 0 bytes of mobile traffic since I came to the US.
For completeness, my phone is Nexus 6P with Android 7.1.2, August security patches installed.
Can someone answer the following questions? I really want to get to the bottom of this.
1. Can mobile data be used by some apps/services even if cellular data is globally disabled in settings?
2. If so, how can I find out which apps/services exactly have the ability to do this? I was browsing through the settings and in Settings -> Apps -> Configure Apps -> Special Access I see a section called "Unrestricted data access". Is that it? I had two apps with this enabled, one was Carrier Services and the other probably was Google Play services ( I don't remember, I disabled both).
3. If some apps/services were using cellular data, why isn't this reflected in the Data usage statistics? Some data got transfered back and forth and I'm seeing 0 B, which is apparently not true.
4. Where can I see how much data has been used in the background?
Thanks in advance!
