Why are we paying for ginormously expensive cell phone bills again? With a wifi connection, you can now:
Talk
Text
Send MMS (think Snapchat)
Do everything else smartphone-wise.
I know a few things that might run into issues - you can't take a call while on the road without cell service. GPS would be a no-go. Things like Google Maps and Nike Running wouldn't work.
But aside from that.... what good reasons still exist for having a cell phone bill?
