Hike Messenger

Most messaging applications need some Internet connection to send messages, even if it’s an old 2G one. Unlike its competition, Hike Messenger can bypass the Internet connection entirely, albeit for a very short range of about 100 meters or a little over 300 feet.
 
This is not the only features of Hike Messenger. Users can also engage the “the hidden mode,” which can be used to protect the messages with a password, they can share documents and files, or use thousands of stickers for their conversation.
 
With Hike, it’s possible to make free calls through the Wi-fi or Internet data plan, and conference calls to up to 100 people at one are supported as well.
