Telefon Messenger

Telefon Messenger is a FREE messaging app available for iPhones and iPads. Telefon 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 SMS to Telefon to send and receive messages, calls, photos, videos, documents, and Voice Messages.

Telefon uses your phone's Internet connection (4G/3G or Wi-Fi, as available) to let you message and call friends and family, so you don't have to pay for every message or call.* There are no subscription fees to use Telefon.
Send and receive photos, videos, documents, and Voice Messages.

Call your friends and family for free with Telefon Calling, even if they're in another country.* Telefon calls use your phone's Internet connection rather than your cellular plan's voice minutes. (Note: Data charges may apply. Contact your provider for details. Also, you can't access 911 and other emergency service numbers through Telefon).
Enjoy group chats with your contacts so you can easily stay in touch with your friends or family.
