If you're used to slapping a physical SIM card into a phone, here's how to activate a Cricket eSIM.

The Cricket Breeze-Thru service makes it possible for new customers to activate their handsets directly from the phone itself.

These prices are good through January 21, 2016 if you bring your own number to Cricket, purchase an eligible phone and your Cricket plan must cost at least $40 per month.

Its mobile app let me buy a phone plan using Apple Pay and tap a few buttons to activate service. With Straight Talk and Cricket, I perused the websites to find their eSIM offerings.
