Yesterday, I [b]added 1GB data plan on my Koodo contract (call/text).
My phone is [b]iPhone6S.
Before that, I was using that iPhone6S for Wind contract (call, text, data) and an old Samsung cellphone for my Koodo contract (call, text only), and I decided to quit Wind and upgrade my Koodo.
The reception got better, but I felt that my data consumption became a bit faster.
I tried LTE first, but since it seemed that it uses too much data, I turned it off and now use 3G, which is what I used when I was using WIND network.
This morning, I went for a small walk. Before leaving the house, my Cellular Data Usage was 1.3MB, and I came back home and it increased to 1.4MB. I understand that.
Since I came back home, [b]the network switched to my house wifi.
About an hour later, I double checked [b]my cellular data usage and it increased from 1.4MB to 1.9MB under wifi for some reason.
I felt weird, so even though I was under wifi (and it says so on my phone screen too), [b]I turned off "cellular data."
[b]A couple hours later, I checked my usage again and it says 2.0MB.
[b]How could it be increasing, even though the data is completely turned off?
It maybe because my phone is misreading wrong data usage...however, I never had this issue when I had a contract with WIND with the same phone.
Can anybody explain what is going on, please?
(PS. I'm not a native English speaker and I hope my writing conveyed my issue properly)
