Our Asia 14 eSIM covers Thailand, Laos, Vietnam and Cambodia with one data allowance. You can travel through the four countries in any order and keep the same eSIM. A 10 GB plan costs $19.99 for 30 days.
Laos is the destination to check carefully. Our Asia 7 and Asia 12 packs do not include it. A plan called “Asia” or “Southeast Asia” needs an exact destination check before you buy.
Networks across the four countries
| Destination | Asia 14 networks | Listed connection type |
|---|---|---|
| Thailand | AIS, DTAC and TrueMove H | 5G |
| Laos | Lao Telecom | 5G |
| Vietnam | Viettel, Vinaphone and MobiFone | 5G |
| Cambodia | Metfone and Cellcard | 4G |
These partner networks are included across all four plan sizes. Your connection depends on the network and signal available where you are. Save your next address and tickets before remote journeys; coverage on an overland route is not continuous simply because both countries are included.
How much data and how many days?
| Shared data | Validity | Price, USD |
|---|---|---|
| 3 GB | 15 days | $6.99 |
| 5 GB | 30 days | $10.99 |
| 10 GB | 30 days | $19.99 |
| 20 GB | 30 days | $39.99 |
Count from the first day you will connect to the last, including days spent moving between countries. The 15-day plan suits a shorter route. For a longer trip, choose enough validity even if your data use is light.
For a 21-day trip, a planning budget of 0.5 GB a day totals 10.5 GB. At 1 GB a day it totals 21 GB. Those are arithmetic examples, not observations about every traveller. Wi-Fi use, uploads and hotspot sharing will change your needs. Pick a starting allowance, monitor the balance and top up if necessary.
At each border
Install once while you have Wi-Fi. Select the eSIM for mobile data and turn on its data roaming at the first stop. Leave those settings in place for the next country. Your remaining data and original expiry time continue; neither resets at the border.
If the connection does not resume after arrival, briefly switch flight mode on and off, then check that the travel eSIM is still selected for mobile data. Follow the network-selection instructions in your installation email if you need to choose a supported operator manually.
When separate plans suit the trip better
If most of your trip is in one country and you only make a short visit to another, compare our Thailand, Laos, Vietnam and Cambodia plans. Their allowances and validity start separately, which can help on a long trip. The regional versus separate-plan comparison explains how to compare the totals without confusing shared data with country-specific balances.
We recommend Asia 14 for this four-country route because it includes every stop and keeps the balance together. That does not mean a regional plan will be the least expensive choice for every combination of days and data.
Adding Singapore to the route
Asia 14 excludes Singapore and mainland China. If Singapore is your final stop, keep Asia 14 for these four countries and choose a separate Singapore plan. Buying a top-up for Asia 14 does not automatically add Singapore coverage.
Check the regional coverage guide if your itinerary includes other destinations, or open the Asia 14 eSIM product page to choose your starting allowance.
