● HAS EXTRA SECURITY OPTIONS, such as setting an extra password for DefTalk, encrypting data on your mobile phone, or using a timer to set a deadline when your conversation history will automatically be erased.

● OFFERS FASTER COMMUNICATION. Thanks to the unique and patented SmartSmile™ technology. SmartSmile™ surveys your conversations and suggests the stickers that you may need. This helps you to compose sentences with just a few taps.
