Common questions
- Does eSIM work in China?
- Technically yes, but VPN restrictions and network policies make it complicated. Most travel eSIM providers offer limited China plans that may not bypass the Great Firewall. Check provider-specific China coverage before buying. Hong Kong and Macau are separate markets with excellent eSIM support.
- How much data do I need for two weeks in Southeast Asia?
- Southeast Asia has excellent public Wi-Fi in cities and tourist areas, so most travelers use 2-4 GB per week. Budget more if you plan to use ride-hailing apps heavily (Grab uses modest data) or navigate by GPS in rural areas. A 5 GB plan is a safe starting point for two weeks with Wi-Fi access.
- Will my eSIM work on islands in Thailand or Indonesia?
- Popular tourist islands like Phuket, Koh Samui, Bali, and Lombok have good 4G coverage. Remote islands may have spotty service regardless of provider. The eSIM connects to the same local towers a physical SIM would, so coverage depends on the destination, not the eSIM brand.
