“And speaking of saving money, did you know you can make free phone calls and texts, and even get a free incoming number? The TextNow app, for iOS and Android, lets you make unlimited calls to any 10-digit number in the U.S. and Canada, over Wi-Fi.”

“Parents who want to keep track of their children but aren’t ready to invest in a kid-friendly Firefly phone can give their offspring an old device stocked with apps like TextNow that keep lines of communication open without a phone plan. And unlike WhatsApp, TextNow doesn’t require a Wi-Fi connection to work.”
