This document describes a solution for mobile operators to generate recurring revenue from prepaid SIM cards sold to inbound travelers. The solution involves converting local SIM cards into global SIM cards using a mobile app. This allows travelers to purchase data plans from local mobile operators in each country they visit using their existing SIM card. This recurring revenue model increases the lifetime value of travelers for mobile operators over ten times compared to the current one-time revenue model. Key benefits for mobile operators include recurring revenue streams from travelers, additional revenue when travelers use partner networks in other countries, and a competitive advantage over local operators.
