I wanted to confirm if zapping of data by network is true because I do experience this on my 9mobile line 1GB month sub gets exhausted within two days. So I made use of the tecno Hi manager app, I set the amount of data I have and started using my phone to browse. I noticed that I don't need to dial *228# to check my data balance cos my remaining data according to Hi manager app always tallies with that of the network, it's not our network z[color=#000099][/color]apping the data rather the uploads of the phone, mind you when browsing you see your browsing speed, that speed is just your download speed, there is actually an upload running simultaneously along with download of information from net, the data usage for upload isn't accounted for. See screenshots below

glo is the best on that, but their network no be here.
Etisalat own worse.

But from the app, I don't think my data was zapped, because my phone could account for every bytes received, whenever I want to check my data balance I just check the one I spent subtract it from total sub, the balance I get is same as the one from network.
