Hi all, My sister really wants a smartphone. I am thinking to get her one, most likey an Android smartphone. BUT I am kind of worried about mandatory data plan, just like the iPhone. No matter where you buy the iPhone, even used ones, it's still require you to have a data plan no matter what. When I bought the Samsung Epix two years ago from a second hand dealer, I just swapped my SIM card to the Epix, and I was ready to go, without getting worried about data usage. So yeah, fast forward today, is there any other smartphones that require to have data plan, just like the iPhone? Thanks all.
