TravelSim offers a dual-profile SIM card solution that provides a seamless roaming experience. The SIM card contains two separate profiles - a local profile for domestic use and a TravelSim profile that automatically activates for lower rates when roaming internationally. TravelSim handles all technical integration and switches the user transparently between profiles depending on location. Partners benefit from TravelSim's extensive network coverage in over 195 countries while avoiding operational expenses and quality issues when roaming. Revenue is shared, with TopConnect retaining 65% to cover costs and the partner receiving 35% as a discount on airtime.
