Telus LG BL40 WIFI question

[mudsharkjr]

So I recently got a LG BL40 from Telus (3 year contract 0 dollar phone) and I picked the clear voice plans (so no data plan) and I was wondering if I have to pay for data usage if I connect through a free WIFI network (like my home internet [also Telus :S so I'm not sure if it's free] or my school network [100% sure it's free]).
Also... I've read a lot of reviews about the LG BL40 and a lot of people are saying it sucks. Is it possible to change my phone without paying more? I got some 7 dollar/month warranty plan that covers water damage and stuff.

Edit: Sorry I know the LG BL40 isn't a smart phone, but this forum seems better than all the others one that I googled. Please answer my question if you can .
Also, I just went on google a minute ago and I logged on my account on Telus and looked at the data usage thing.
It says I used 4 kB... strangely it costs $0... why? Is my actual bill gonna be different? I added the "Data Services Block" to my plan and removed the "Pay-Per-Use Data". Will I still be charged if I use a free WIFI network?

No, you don't have to pay to connect through WiFi, but make sure to turn the WiFi and Bluetooth off when you're not using them to drastically increase your battery life.
