Your SouthESIM plan for Hong Kong is specifically designed for use within Hong Kong itself. While Macau and Shenzhen are just a short trip away, they operate on different telecom networks, and Mainland China has its own internet regulations (the firewall!). If your travel plans include visiting the wider Greater Bay Area, we highly recommend exploring our multi-country Asia bundles. They offer broader coverage, ensuring you stay connected across all your destinations without any interruptions.
