I installed Hike messenger in my android smartphone from play store as per recommend by my friends. Normally we friends use it for group discussion and to share files without internet connection during our class session. it has huge collection of Free SMS, creative animated stickers and News Feed. hidden mode in a press, privacy options that reduce the stress.
Sometimes faced problem with conference call with Hike found not so successful with free calls facility. provide good collection of theme option. For chat and to share files, hike is one of the best app. I impressed with updated version of hike, working smoothly and responding fast on every action.
