Get a 64GB iPhone SE (2020) for $15 per month at Mint Mobile and you'll be able to sign up for a two-year 3GB Unlimited plan for an additional $15 per month. Normally, the $15 per month Unlimited plan promotion is limited to just three months. This is also $10 off the monthly price for the 3GB Unlimited plan, so you'll be saving $240. After two years, the plan's price will return to $25 per month. The 8GB and 12GB Unlimited plans are also discounted and drop to $20 and $25 per month for two years. A seven-day money-back guarantee is included. Additional taxes and fees may apply.
