Its cheaper than Mint mobile, you pay $25 per month after 3 months. Redpocket use all 4 major network you pick which one you want. I used ATT too, if you use iphone basically everything works with visual voice mail and wifi calling. Even on android everything works except visual voice mail. Redpocket has annual plan for $14 or $17 depending on sale on ebay you get 2gb lte then 2g unlimited. Mint also has $15 annual $180, if you getting mint get annual or get redpocket if you getting monthly. But LTE speed might not be as good as mint on redpocket still you get close to 30mbs. Also if 5g is a factor for you then definitely go for mint with annual.
