Mint Mobile is well-known for its extremely affordable, no-frills services that typically require customers to pay for months to a year ahead of time in order to get rates that are hard to beat elsewhere. This was especially true for new customers until fairly recently, as you could previously get a year of unlimited service for just $180 upfront, or what works out to an outstanding $15 a month.
Unfortunately, this promo has finally ended, and so the same price will only net new customers a 15GB a month data allotment (currently on sale for $14 per month). While Mint is known for offering recurring deals from time to time, right now, there’s less incentive to jump into an unlimited annual plan with the carrier.
