Unlocked phone with at&t service
I am currently on at&t customer, and plan to buy an iphone and unlock it in order to use my current rate plan (without data plan).
I have research about wifi on unlocked phone, and it seems to look
if I have at&t service, the edge would have priority over wi-fi.
My question is that
even though I am not having any data plan, I would be charged for using internet in wifi available area because of Edge priority?
I will always use wif for internet and never want to use EDGE. If i have an at&t service, do I have to install deedge application?
