Hi guys. I need your help to buy a Galaxy S3 for my girlfriend. I am complete noob in terms of cell phones. I have old simple phone myself and never paid attention to cell phones market. I found this one on Amazon.ca http://www.amazon.ca/Samsung-GT-I9300-Unlocked-Smartphone-Quad-Core/dp/B008AFZ2VO/ref=cm_rdp_product Maybe you guys have other suggestions where I should buy it. I have few questions: 1. If I buy it will it work with Rogers Canada provider? 2. Do I need to install anything or it is ready to work out of the box. If not how complicated it is to make it ready. Also I found a guy asking something about compatibility with Canadian carries. Here is his question. I would like to buy this phone but want to make sure it comes with 4G (LTE) compatible with Canadian carriers (e.g. Bell, Rogers, Fido, etc.) I called amazon.ca customer service, they asked me to call samsung canada. I called samsung canada and they said it was not manufactured by samsung canada so they couldn't tell. I called amazon.ca again and they said they had no further information other than what was on the product page. The product page said "4G(dependent on market)." It really doesn't help as I have no idea what market this I9300 model was supposed for. Maybe someone here can answer. Sorry for long post and thanks in advance.
