Mint Mobile SIM cards come at no extra charge when customers purchase service through Mint’s website.
It’s also possible to purchase Mint SIM cards (and sometimes service) through Amazon, Target, or Best Buy.
SIM card styles
Mint Mobile’s SIM cards typically come in the 3-in-1 style. 3-in-1 SIMs can be sized to fit standard, micro, and nano SIM slots.
For those with compatible phones, Mint Mobile offers eSIM plans, negating the need for a physical SIM card.
