  • Friends and Family – Enables subscribers to self-manage a list of telephone numbers that they can call at discounted rates or for free. Subscribers can add, change and delete numbers from this list according to usage limits.
  • Balance Enquiry – Enables mobile phone subscribers to retrieve information about their accounts, such as their account balance, dedicated accounts, airtime expiry, and MSISDN in a single transaction.
  • Credit Transfer Module – Enables prepaid and post-paid mobile phone subscribers to transfer airtime and other credit such as data and SMS to other subscribers.
  • Subscriber Loyalty Centre – Rewards subscribers for loyalty and network use by monitoring network events and triggering rewards on a time or usage basis.
  • Subscriber Life Cycle Management – Allows the operator to trigger rewards and notifications based on subscriber life- cycle events and account threshold events. For example, anniversary bonus or low balance warning messages.
  • Configuration Managed Services – A collaborative approach allows leveraging existing functionality to realise operator needs, dramatically improving time to market.
  • Call Me Back – Enables mobile subscribers to send “Please Call Me” requests to one another when they run out of or are low on airtime credit. This service significantly increases voice traffic and provides a mobile advertising platform.
  • Tariff Plan Migration – Enables mobile phone subscribers to switch between tariff plans (service classes) that offer them different voice and data services, and rates.
  • Third Party Top-Up – Enables subscribers to recharge other subscribers’ accounts, as a gift or a favour, using voucher numbers. Instead of recharging their own account, subscribers can transfer a recharge amount to their friends and family.
