SMS Instant is a free iPhone app developed by Hayato Shimizu. It falls under the category of Utilities & Tools and offers a convenient solution for obtaining disposable phone numbers for receiving SMS messages without registration.

With SMS Instant, users can easily acquire temporary phone numbers that can be used to receive registration messages from various platforms such as Facebook, Twitter, Paypal, Alipay, and more. This provides a secure way to receive messages without exposing your private phone number.

The app proves useful in various scenarios. For instance, when a temporary telephone number is required for trial registration of a service, when you want to receive SMS messages anonymously, or when you need a phone number for SMS in a hurry. It also caters to those who wish to receive messages without divulging their private phone number.

Using SMS Instant is simple. Upon launching the app, a disposable SMS phone number is automatically assigned. Users can then share this number with the intended sender. As long as the app is running, they can receive the SMS messages sent to the disposable number. Each time the app is relaunched, a different phone number will be assigned.
