Asia is the one region where almost nobody visits just one country. The classic Southeast Asia loop hops Thailand → Malaysia → Singapore → Indonesia; Hong Kong and Macao happen in the same weekend; Japan and South Korea pair up in spring; and the digital-nomad trail strings together Chiang Mai, Bali, Kuala Lumpur, and Da Nang. A Jet eSIM for Asia gives you one data plan, installed before you fly, with 5G speeds across 18 countries — the moment you land at Bangkok (BKK), Changi (SIN), Incheon (ICN), or Narita (NRT) you’re online: no SIM counter queue, no passport registration form, no roaming bill waiting at home.
Why Jet eSIM
Three things separate an Asia trip from other destinations when it comes to mobile data:
01
A month in Asia usually means four or five countries, and even a short break often crosses one — Hong Kong with a Macao day trip, Singapore with a Johor Bahru weekend. Buying a local SIM per country means repeating the airport-counter ritual at every landing: queues, passport registration, tourist pricing, and a new phone number each time. The Asia eSIM plans cover 18 countries on one eSIM with one data allowance — it connects to the local network by itself every time you cross a border.
02
Grab and Gojek for rides, LINE and KakaoTalk and WhatsApp for everything from hotel check-ins to street-food orders, Google Maps for the alleys of Tokyo and Hanoi, translation apps for the rest. None of it tolerates a slow connection — and Asia has some of the fastest mobile networks on earth (Singapore, South Korea, Japan, Taiwan, Hong Kong). The Asia eSIM plans run on 5G/4G/LTE, so you get the speed the region is famous for, with a baseline of 3–5 GB per week for casual use — or 10 GB+ if you’re hotspotting a laptop.
03
From a 3-day stopover to a six-month nomad stint, the Asia eSIM plans scale with the itinerary: fixed plans from 500 MB up to 100 GB with validity from 3 to 180 days, plus unlimited options from 3 to 30 days. Match the plan to the trip instead of re-buying a new eSIM at every border — and top up online if you run low mid-journey.
Pricing
All plans run on the Asialink network with 5G/4G/LTE speeds and work in every covered country — the same plan connects in Bangkok, Tokyo, Singapore, and Seoul. Data-only. Top-up available while abroad.
| Data | Price (USD) |
|---|---|
| 500 MB / 3 days | $1.99 |
| 1 GB / 7 days | $3.90 |
| 2 GB / 15 days | $5.90 |
| 3 GB / 30 days | $10.90 |
| 5 GB / 7 days | $11.90 |
| 5 GB / 15 days | $11.90 |
| 5 GB / 30 days | $11.90 |
| 10 GB / 7 days | $17.90 |
| 10 GB / 15 days | $18.90 |
| 10 GB / 30 days | $19.90 |
| 20 GB / 30 days | $30.90 |
| 50 GB / 7 days | $43.90 |
| 50 GB / 15 days | $45.90 |
| 50 GB / 30 days | $47.90 |
| 50 GB / 90 days | $55.90 |
| 100 GB / 180 days | $72.90 |
Handy quirk: 5 GB costs the same $11.90 whether you pick 7, 15, or 30-day validity — always take the 30-day version. For long stays, the 100 GB / 180 days plan works out to roughly $12 a month.
Setup
Choose an Asia plan with the data amount and validity that match your trip. You’ll receive an activation QR code by email within minutes of purchase.
Once your plane touches down anywhere in the covered region, your Jet eSIM activates automatically. Maps, Grab, LINE, and hotspot work from the moment you leave airplane mode — and when you cross into the next country, the plan switches to the local network on its own. Just keep data roaming enabled.
Coverage
The Asia plan runs on the Asialink network, connecting to leading local carriers in each country — KDDI in Japan, AIS in Thailand, Telkomsel in Indonesia, Singtel in Singapore, SKT in South Korea, and other partner networks — with automatic switching as you cross borders. One plan, 18 countries:
Coverage is strong across cities, transport corridors, and tourist regions. Remote islands and mountain areas depend on local carrier towers, same as any local SIM.
Not on the list? Destinations like Nepal, the Maldives, and the Caucasus and Central Asian countries aren’t part of this regional footprint — use country-specific plans for those instead.

FAQ
Yes. Install the eSIM before you fly, and it activates as soon as your phone reconnects to a mobile network after landing — Bangkok, Singapore, Incheon, Narita, Hong Kong, and every other covered airport included. You should see mobile data available before you clear customs.
Eighteen: Thailand, Vietnam, Indonesia, Malaysia, Singapore, the Philippines, Cambodia, Laos, Japan, South Korea, China, Hong Kong, Macao, Taiwan, India, Sri Lanka, Bangladesh, and Pakistan. Nepal, the Maldives, and Central Asia are not included — use country-specific plans for those.
Yes, China is included in the coverage. One heads-up: many Western apps — Google, WhatsApp, Instagram — are restricted by local network controls there. Jet eSIM’s built-in privacy tools are designed for exactly this situation, but test them right after landing and don’t rely on connectivity for anything critical on the first day.
For a typical month — maps, messaging, social media, occasional streaming — 20 GB covers most travelers, and the 20 GB / 30 days plan is priced for exactly that. Heavy users on nomad schedules should look at 50 GB or the unlimited / 30 days option.
Fixed data is far cheaper per gigabyte; the 5 GB / 30 days plan at $11.90 is the sweet spot for short trips. Unlimited makes sense for 5–10 day trips where you’ll be streaming, hotspotting, and navigating constantly without wanting to watch a counter.
Yes — the 100 GB / 180 days plan ($72.90) is built for exactly that: roughly six months of coverage across all 18 countries for about $12 a month, with hotspot included for laptop work.
Yes. Every Jet eSIM Asia plan supports hotspot sharing, so you can tether a laptop, tablet, or another phone. Data used via hotspot counts toward your plan allowance.
Yes. Jet eSIM runs alongside your original SIM. Your usual number stays active for calls and SMS — including bank verification codes — and your Asia data runs on the eSIM.
