S3 SNS app for iPhone and iPad

S3 Notification Service (SNS) is cross-platform messaging application that lets you securely and reliably deliver messages. SNS uses your phone’s Internet connection (4G/3G/2G/EDGE or Wi-Fi, as available) to let you message and call friends and family. Switch from traditional e-mail messages or SMS to receive messages on the go and wherever you go.

WHY USE SNS:
• SAY NO TO USERNAMES AND PINS: Why bother having to remember yet another username or PIN? SNS works with your phone number, just like SMS, and integrates seamlessly with your phone’s existing address book.
• OFFLINE MESSAGES: Even if you miss your notifications or turn off your phone, SNS will save your recent messages until the net time you use the app.
