GSM plans FAQs

What is the cheapest GSM cell phone plan?

MVNOs like Mint Mobile, Tello, and Boost Mobile offers the cheapest cell phone plans, with prices starting at just $10 per month. You could save up to $600 per year from your phone bill.

What is the best prepaid GSM plan?

T-Mobile MVNOs and AT&T MVNOs operate on the main networks so carriers like Ultra Mobile, Ting, and Mint Mobile use the GSM network.


Recap

MVNOs offer an affordable way to get access to the main US networks, with the same perks and quality coverage.

GSM (Global System for Mobile Communications) is one of two technologies that fill in the gap when 4G is not available. T-Mobile and AT&T both use GSM, along with their MVNOs.

If you're looking to bring your own phone you'll need to check it's compatible with a GSM carrier. You can do this with our IMEI checker.
