Found some phones for cheap on amazon and it says they work with GSM Carriers and not CDMA Carriers. Comments are saying that it works with all Canadian carriers, but I'm unsure as nobody has mentioned Chatr as of yet.
Hi Kathryn. Hi Kathryn. As long as your phone supports 3G networks and it's unlocked, then you should have no problem using Chatr's network with your Samsung Galaxy A7.
