mFamily is an Android application developed by MobiFone Viet Nam, available for free in the Utilities & Tools category. It is an exclusive service for Mobifone subscribers, designed to provide cost-effective solutions for families or groups of people. With mFamily, subscribers can purchase packages of voice and data at favorable prices, along with unlimited and free internal-group calls.

One of the most significant features of mFamily is that it allows access to packages with unlimited data, which is particularly useful for families who have different mobile traffic needs. The app also allows proactive traffic sharing of voice and data between members, making it easier for everyone to stay connected. The Group Administrator is responsible for managing the account, which includes purchasing, renewing, and topping up mobile plans, as well as setting voice and data traffic limits for each member.
