Asia eSIM: compare country plans and regional coverage
The best Asia eSIM for your trip depends on the countries you visit, the days you spend in each and how much data you use. Use this directory to compare country plans, then check whether a regional bundle covers your exact itinerary at a better total price.
Single-country fixed-data plans for these destinations start from $1.99.
How Asia works for mobile data
The country links below are a buying directory, not the coverage list of one Asia bundle. Open the selected offer's country list and check every stop individually, including transit stops where you plan to connect. Similar Asia or Southeast Asia labels can describe different country memberships.
For Bangkok–Siem Reap–Ho Chi Minh City or Japan–South Korea, compare a regional allowance with the total cost of separate country plans for your dates. Check activation timing too: a first supported connection during a covered stopover can start validity before you reach your main destination.
Check the exact plan's networks and service terms for islands, rural roads, mountain routes and rail journeys. Country coverage does not guarantee continuous signal. If you need mainland China, confirm it explicitly in the offer and check the service restrictions for the apps you need; an Asia label alone settles neither.
Asia countries and prices
USD prices compare single-country fixed-data plans from our current catalogue. The entry price and lowest price per GB can come from different plans. Daily and unlimited plans are excluded; check each plan's allowance, validity and final checkout total.
Single-country or regional?
One country
Compare that country's plans with regional offers for the same allowance and travel dates. Additional countries add value only if you will use them. A lower price per GB can still mean paying more for data you do not need.
Southeast Asia backpacking
For Thailand–Vietnam–Cambodia–Laos or Bangkok–Singapore, confirm every country in the selected regional offer. Compare validity for the whole route, activation at the first stop and whether top-ups are available. Crossing a border does not reset a fixed-data allowance.
Japan and South Korea together
Compare separate Japan and South Korea plans with a regional bundle listing both. Add the country-plan prices for the days you will actually use each, then compare that total with the regional option and its activation rule.
Island-hopping in Indonesia or the Philippines
Compare an Indonesia plan for Bali and other Indonesian stops, or a Philippines plan for Philippine islands. Check your precise route and supported networks; a country listing does not guarantee signal on every island or during ferry crossings.
How much data to buy
Use your recent mobile-data usage to estimate your trip allowance, allowing for maps, transport apps, translation and messaging away from Wi-Fi. Streaming, video uploads and laptop tethering can change that estimate substantially. For daily or unlimited plans, check hotspot permission, the high-speed allowance, its reset and any reduced-speed tier.
Full data-budgeting guideAsia eSIM questions
How do I choose the best eSIM for Asia?
List every country and travel date, then compare country plans with a regional bundle covering those exact stops. Check total price, data, validity, supported networks, activation and hotspot rules. The best fit depends on your itinerary; a regional label or low price per GB alone is not enough.
Does an Asia eSIM work in China?
Only if mainland China appears in that exact offer's coverage list. Check the service terms and app access you need before purchasing. The country directory on this page is not a coverage promise for a regional bundle.
How much data do I need for two weeks in Southeast Asia?
Start with your phone's recent usage and estimate the data you will need away from Wi-Fi for the full two weeks. Offline maps can reduce usage, while streaming and hotspot sharing increase it. Check top-up availability if your needs are uncertain.
Will my eSIM work on the Japanese shinkansen and subway?
Service depends on the exact network, route and conditions. Interruptions are possible underground, in tunnels or in remote areas. Save tickets, maps and travel details offline before setting out.
Is one eSIM enough for a Southeast Asia backpacking trip?
One regional eSIM can serve the trip if it lists every destination and its validity covers your dates. Check Laos, Cambodia, Vietnam, Thailand, Malaysia and Singapore individually as relevant to your route; do not infer membership from the Southeast Asia label.
Does eSIM work in Bali?
An eSIM-compatible, carrier-unlocked phone can use a plan that includes Indonesia, subject to its supported networks and terms. Check your specific Bali and onward-island itinerary; a country listing does not guarantee signal everywhere.
