How does text plus work?

TextPlus is a communication app that provides users with a free phone number for sending texts and making calls over Wi-Fi or mobile data. Users can send unlimited text messages and make calls to other TextPlus users for free, while calls to non-TextPlus numbers may incur charges. The app also offers additional features like group messaging and voicemail. It monetizes through ads and premium services, such as removing ads or obtaining additional features.
