Frequently asked questions
Which eSIM options are best if I'm traveling to multiple countries in Asia?
You can choose regional bundles from Airalo or regional passes from Saily. There's also a broad Best Asia regional plan from Ubigi and a massive marketplace like MobiMatter where you can compare various providers for different destinations.
Are there any eSIMs that offer unlimited data for my trip?
Holafly offers unlimited data eSIM plans specifically for tourists visiting places like Japan, Thailand, and Vietnam. Most other providers in this list focus on fixed data amounts or per-gigabyte pricing.
I'm looking for the cheapest data rates in Asia. What should I look for?
Nomad is a strong choice since their per-gigabyte pricing in parts of Asia can drop as low as $1.10. You might also check out MobiMatter to compare prices from over 30 different providers to find the lowest rate.
Can I buy an eSIM at the same time I book my flights or hotels?
Yes, Trip.com allows you to add an eSIM as an in-app add-on right after you book your travel through their platform. This makes it easy to handle your connectivity and bookings in one place.
Is there a difference between companies that own networks and those that resell them?
Yes. While many options are resellers, Ubigi is backed by NTT DOCOMO, which gives them a strong footing in Japan, South Korea, and Thailand. CMLink is also different because it's operated by China Mobile International and sells its own branded eSIMs.
