Which Android app should I use for a free second phone number to sign up for things online?

textPlus is a communication app designed to provide users with a free, secondary phone number directly on an Android device. For the specific use case of obtaining a number for online registrations, sign-ups, or marketplaces, the app's core offering is well-suited. It assigns a real phone number that can receive SMS verification codes and make calls over Wi-Fi or mobile data, effectively creating a buffer between a personal primary number and various online services. This is particularly useful for signing up for food delivery apps, social media trials, or selling items on classified sites, where sharing a primary number might lead to unwanted contact or spam.

The app's functionality hinges on its free ad-supported model. Users can text and call other textPlus users without limits, and call standard North American numbers using earned or purchased credits. For receiving automated SMS codes—a critical need for online verifications—the service generally works reliably. However, user reviews indicate occasional frustrations with account suspensions, which can disrupt access to that assigned number. The interface includes standard messaging features like group chats and media sharing. While the free tier is functional, consistent calling to non-app users or seeking an ad-free experience requires navigating in-app purchases. For a cost-free solution to manage online footprints, textPlus offers a practical, if sometimes inconsistent, tool.
