What You Need to Know

As one of the newest carriers to hit the US, Mint SIM is offering affordable contract-free rates using the power of the T-Mobile network. While their monthly service rates aren’t anything too different from the usual, they offer substantial discounts for paying in advance.

Currently, options include monthly, 3-month, 6-month and 12-month payments. At the one month level, plans range between $35 and $60 per month. At the yearly level, plans range between $16.58 and $33.25 per month.

If you need a new phone, their selection is currently lacking. However, support for most unlocked GSM phones allows you to find a phone on Amazon or bring yours with you by swapping in one of their SIMs.

If saving money is a big concern for you

from The Gadgeteer
If you’re on a budget, definitely check into Mint SIM. As long as your area has good T-Mobile coverage, they are a viable alternative to Verizon, T-Mobile, Sprint, and AT&T... Full review

Very affordable pricing, spotty LTE data speeds

from Android Central
Mint SIM is a great choice for people who don't need tethering, and can deal with a few occasional slowdowns when it comes to cheap wireless data service... Full review

Aggressive plans pricing and well worth your consideration

from Android Guys
Carrier plans are not something I personally give a lot of thought to. My family has always been with one of the large carriers and my work gives me a discount on my plan so I’ve been a little complacent. The only thing that holds me back from switching over would be the lack of a “family style” plan. There is currently no price break for multiple lines. That being said, the prices, if we break them down to a monthly cost, are very aggressive and this only makes things better for us as consumers... Full review

Darn, there are no reviews yet for this carrier.
