Frequently Asked Questions
With a regional Asia eSIM, you'll get automatic network switching in covered countries. Coverage typically includes major nations from Japan to Turkey, though you should verify specific country lists with your provider. Some borders (like China-Hong Kong) may require manual network selection.
Most eSIM providers offer instant top-up through their apps using remaining data. As a backup, you can purchase top-up codes at convenience stores in most countries or ask hotels to help with online purchases. Always top up before your data completely runs out.
Absolutely. Navigation uses minimal data (5-10MB/hour), leaving plenty for music streaming (150MB/hour). A 10GB plan could provide 1000+ hours of navigation or 60+ hours of music streaming. Enable offline maps and downloaded playlists to conserve data.
Yes, if you set up dual-SIM properly. Keep your home SIM active for calls/SMS (turn off its data), while using the eSIM for data only. WhatsApp will continue working normally, and you'll receive all banking OTPs without interruption.
Urban areas in South Korea, Japan, Singapore, and China often have 5G (100+ Mbps). Highways typically offer 4G LTE (20-50 Mbps), sufficient for all navigation and communication needs. Remote mountain passes may drop to 3G (1-5 Mbps) but still support basic navigation.
Offline maps are your insurance policy. Download Google Maps offline regions or use Maps.me before entering remote areas. Most GPS navigation works without data once maps are cached. Emergency calls work without any SIM card in most countries.
Yes, enable personal hotspot to share with 5-10 devices. Monitor usage carefully as hotspot sharing can consume data quickly (1-2GB per day with multiple users). Some plans have hotspot restrictions, so verify before purchasing.
Most regional plans cover both zones, but coverage varies by provider. East Asia (Japan, South Korea, Taiwan) might be one profile, while Southeast Asia (Thailand, Vietnam, Malaysia, Indonesia) could be another. Check if your route needs multiple profiles.
