You need $15 and an Unlocked GSM Phone

Use an  Unlocked Phone

Even a Dual-SIM phone

You can use the sim card with a dual-SIM unlocked GSM phone. If you need the phone while traveling in the USA, then a dual-SIM phone allows you to use it with two carriers without having to keep switching out the cards.

Use a Previous T-Mobile Phone

This is a great way to use your or a friend’s old T-Mobile phone. This way, even if you previously had contract service, you can switch over to prepaid or no-contract service. Re-using the phone immediately is probably much more efficient than sending it off to be recycled.

But Don’t Try to Re-Use a Tracfone!

Tracfone handsets airtime mechanism is usually locked in the firmware, and it’s quite difficult for an individual to unlock.

Starter Airtime

The SIM cards each come with 10 minutes of starter airtime. This is basically just enough to make sure your phone is functioning properly before you spend your own money on airtime.

It’s a good idea to buy $100 of airtime if possible to receive the 15% bonus as well as extending your service for a whole year.
