I have a phone on ex boyfriend plan and wanting to get away. I was wondering how much gig should I get. I mostly use it for gps, facebook, pinterest, weather bug, and amazon and my miscues I download. I use wifi at home and always check if places has it. Would 3 or 5 gig a month work. I am home alot so use my wifi. And was wonder if the lg g4 is better then s6. I have s5 and haveing problems
