I switched from an Android phone to a new iPhone 6 in Dec 2015. The Koodo shop in Markville Mall installed a new SIM card on the new phone. I requested the old plan (no data) to remain unchanged on the new phone. She said nothing had changed.
When I received my last bill, I saw two data usage charge, $5 each. One was incurred on the same day I activated my new iPhone. That charge was the use of 3.67 MB of data. The second one was for Data Usage US for 0.00 MB. I did drive to the US on that date. When I saw the charges, I checked the Cellular Data setting on my phone and it was off. I also checked the WI-FI Assist setting and it was off, too. I knew about data & roaming charges as I travel often. I was very careful in setting data and roaming off.
Another similar charge has appeared in the current billing cycle. It was again $5 for Data Usage US of 0.00 MB. Again I checked the settings and Cellular Data and WI-FI Assist remained off. I will be in the US for a while and I have chosen to live in resorts or hotels that have excellent WIFI.
1. How can I stop these data usage charges? I have turned off Cellular Data and WIFI Assist.
2. Could you revert those charges? I have tried my best to use my phone only on WIFI. I did not use voice or text on the phone.
