    Please elaborate if I misunderstood your question. When you are connected to WiFi, data is not used over the network. It's one or the other. I can't think of any a apps that don't work on both. Skype didn't work over cellular until 2010 and FaceTime was initially WiFi-only, but FaceTime has worked over cellular for years (as long as the cellular provider enabled it).

    Well, this what I come from. AT&T notified me that I almost go over my data limit. I was at 90% of my cap. So I turn on the wifi and used my phone with it. But I received message states my data was over 17 MB next morning. So I wonder when I used my phone under Wifi, would that be using cell network in the same time ?

    Be sure to use WiFi whenever it is available. The phone doesn't use both cellular and WiFi at the same time. A lot of people have reported small amounts of cellular data being used while they are sleeping and the phone is in standby. I believe this is because it doesn't count all of the data in real time and it has to catch up on the count. It also might fall off of WiFi and use small amounts to check email and provide other push services. You have to be paying close attention to it to notice this. If you have been using cellular where WiFi is available, you'll likely notice a large decrease in overall monthly cellular data usage.

    I have 3 phones on my Verizon service that are LTE. Another is 3G. The LTE phones a use little bits of cellular data while on wifi. I can see them listed on the spreadsheet at My Verizon. Most are small amounts like .006 mg, but there's a lot of them. A few are larger. I had one that was 65mb, and had no clue what it was. I do very little off wifi. Mostly just calls and texts. My 3G phone doesn't do that. The image shows some of these from my own phone. All the little usages were at times when I was on wifi. Do you know what causes that?

    Could be the Cell Network Search.
    Settings/Privacy/location services/System Services

    Could be. I turned it off to see what happens. It's not an issue, as we have 4 gb of data on the Family Share Plan. All 4 phones have wifi. I was curious though.
