Here’s how it works. The best cheap cell phone plans out there can give you as much data as you need, while keeping your monthly wireless costs under $40. That may sound too good to be true ...

Alongside the Economy plan, Tello also offers a no-data plan for people who only use their phones to text ... while you’re overseas, talk to your provider about the cheapest offers.

Go Talk Wireless’ prepaid plans can be activated by a SIM card or a digital eSIM, which provides fast setup, and you can port your phone number from another provider or get a new number.
