5 to 10 GB
One to two weeks, multiple countries
The sweet spot for most trips. Around 5 to 10GB covers one to two weeks of everyday use across several countries, maps, social media, photos and the odd video call, all on the one regional plan.
20 GB+
Long trip, video or hotspot
For longer stays, regular streaming or sharing a hotspot with a laptop, choose 20GB or more. Some plans are sold as unlimited, which here means a set full-speed allowance each day rather than truly endless data, so check the daily cap before you rely on it.

Why Simzora for Asia
No hype, just how the service actually behaves once you land.
One plan across the whole region
A single plan roams across Thailand, Japan, Singapore, Indonesia, Vietnam, Malaysia, South Korea and more than thirty other countries in the region. As you cross borders it switches networks automatically, connecting to leading local partner networks. There is nothing to swap and no new SIM to buy at each stop.
Honest per-GB pricing, no fake unlimited
We price by the gigabyte and show the cost per GB, so you can compare plans honestly. When a plan is labelled unlimited, it means a set amount of full-speed data each day, after which speeds are reduced, not truly limitless data. There are no hidden throttling surprises, just a clear daily allowance.
Instant, data-only, keep your own number
Your QR code arrives by email within minutes, so you can install before you travel and connect on arrival. It is data-only, so keep your home SIM active for calls, texts and bank OTP codes, and use WhatsApp over the data connection. The eSIM starts counting only on your first connection in Asia, not when you buy it.
Best eSIM for Asia, FAQs
Straight answers to the questions travellers ask most.
Which eSIM is best for Asia?
For a trip that crosses borders, a regional Asia eSIM is usually the best choice. A single Simzora regional plan works across 20 countries, including Thailand, Japan, Singapore, Vietnam and South Korea, so you are not buying and swapping a SIM in every country. It connects automatically to local partner networks.
How much data do I need for a trip around Asia?
As a rough guide, light use of maps, messaging and a little browsing runs around 1 to 2GB a week, while regular social media, photos and video pushes that to 5 to 10GB over a fortnight. If you plan to stream, video call often or share a hotspot, budget 20GB or more. Because pricing is per GB, you can start with a smaller plan and top up if you run low.
Does one regional plan really cover every country?
Yes for the mainstream destinations. One Simzora regional plan roams across Thailand, Japan, Singapore, Indonesia, Vietnam, Malaysia, South Korea and more than thirty others on local partner networks. A few places sit outside typical regional coverage, mainland China being the usual example, where a dedicated country eSIM works better because of local network restrictions. Check the country list on the product page before you buy so you know exactly which networks you will connect to.
