My second phone is on Google's Project Fi or sometimes called Google Fi. It uses the strongest signal from T-Mobile, Sprint, and U.S. cellular. The phone is $20 a month for unlimited calls and texts, plus low international rates. Great selection of Android phones as well.

Data is pay as you go at $10 a gig, but you get credit for the portion you don't use. Use my referral link and get a $20 credit. Noice! Click Here
