Just got a note 4 for $200.
Me and my wife went from a $200 phone bill per month for 2 lines to $90 a month.
Coming from ATT I was a little skeptical about cricket thinking it was some lame phone service. Turns out they use the same towers as and are owned by ATT. They have no contracts so I figured I would give it a month trial run.
I've now had them for 1 year, have never had a problem with their service or speed, and get 20 gigs a month (promo they had when I signed up). Never going back to contracts.
