BlackBerry Messenger, the mobile Instant Messenger, has triggered several rivals such as Facebook Messenger, WhatsApp, WeChat, LINE, Viber and Hike. All these mobile instant Messaging services compete with each other on mostly three fronts – voice calls, video calls and stickers. Today, BlackBerry has pushed the BlackBerry Messenger version 2.1 App update for the Google Android and Apple iOS devices. The new BBM 2.1 app brings support for Stickers along with BBM Shop offering free as well as paid stickers. 
BlackBerry Messenger 2.1 version will make the app compete with the likes of Viber, WeChat and LINE that offer Stickers. BlackBerry has not only added Sticker supports but also introduced a BBM shop that will offer free as well as paid sticker packs. 
The new update also enables sharing the images in groups and after that, expect being bombed by pictures from other contacts in the group chat. Apart from that, the individual file size has been bumped to 16 MB so one can share high quality images and longer video files. Do note that large file size limit also means more data consumption if you are using Mobile Data connection to download those files. Apart from that, the BBM version 2.1 brings under the hood improvement.
BlackBerry Messenger version 2.1 app update is available in the Google Play Store, Apple App Store and BlackBerry World.
