Occupies more space in phone with database. Dont know what is that database why storing. Most of the time sending messages takes time even more than a minute in using 4g and 6gb RAM also. Utilizing more RAM memory. No option for sending messages more than 5 people worst than normal SMS we can send 150 people at a time. Not much difference than whatsapp and whatsapp Business. Waste of time to select each contact one by one. For simple useless app features. Legacy in forwarding msg
