I'm no fan of metropcs, but with some of there new smartphones and limited time offer of unlimited text, talk and 4g data for 55 bucks may be the way to go.
I am unlimited 4g data with 450 minutes and no texting grandfathered in at verizon for around 75 bucks a month. I had my wife on my plan and was paying 50 for 10 gigs of data (Got lucky with tje half price data sale) but I had to bump my minutes up 1500 because she's a talker. My bill for both of was over a 180 dollars.
I lost my job and kicked her to metro pcs with an lg motion and unlimited everything including 4g data for 55 dollars a month. The 4g speeds are compareable to verozons 3g speed or a little faster. The lg motion has a 1.5 gig dual core processor and a gig of ram! The metro pcs website said 1.2 but was wrong.
Maybe that can be an option of you live in a metro pcs 4g area and you can probably get the phone for under a 150 bucks online.
