I have a two-year old iPhone and it's up for upgrade but I'm just had constant problems with iPhones and want to switch to maybe an S5. The problem is, most of my friends have iPhones and I rely on iMessage to use wifi a lot because at least 50% of the time I'm in an area with no reception but perfect wifi. I know the S5 wont use iMessage, but does it have something substantial that will constantly and efficiently send and receive messages using just wifi?
