Re: why is my account showing i am using data from my plan when i am on wi fi
Sorry to hear it appears you've used data up even though you are on WiFi.
Data should only be used when the WiFi signal drops. You'd be surprised how little time it takes to use 100mb of data. The only way to be 100% sure you will not use any data would be to turn data off on the handset.
If your not sure how to do this let me know which phone you have and I can instruct you how to do this.
