Prepaid roaming subscribers are still not free to use their mobile phones universally wherever they travel
. This restriction on roaming freedom is mainly due to complications in real-time charging. As a result, prepaid roaming customers have to resort to other ways to make and receive calls, such as buying local prepaid SIM cards in the visited countries, or using calling cards resulting in lost revenue for both the home and visited network operators. Starhome's Prepaid Anywhere fillsthe gap, allowing prepaid customers to seamlessly make calls and use VAS (value added services) as they roam internationally, providing the same end-user experience as postpaid roamers receive.
