Now, you do not need to spend some units to know the amount of your credit left. The Call & Credit Notification SMS is a new service that enables customers to know their credit of unit. After making any call or sending any message, a free-of-charge flash notification message will appear on the screen of the mobile telling the customers the credits of units left. Thus, we not only sustain your loyalty in our company and the accurate system we are using, but also share with you the benefits of this technology.
