It's important to note that your SouthESIM plan for Papua New Guinea is specifically designed for use within PNG. Many travelers connect through major hubs like Brisbane (BNE), Cairns (CNS), or Singapore (SIN). While these are excellent transit points, your PNG-specific SouthESIM will not provide data services during your layover in these countries. If you need connectivity during transit, consider one of our multi-country Global South bundles or a regional plan that includes your transit country for seamless connection.
