29 countries in this guide · The same NXTL eSIM works across 180+ countries · Balance never expires
You do not purchase or install a separate regional eSIM. It is the same reusable NXTL eSIM and shared balance used across all globally supported destinations.
See every stop before you set off.
Search a country to see its current starting rate and supported network count. Open the country guide for operators, 5G or LTE details, arrival advice and a local trip estimate.

Estimate every stop on one balance.
Add the countries on your itinerary and estimate data for each one. NXTL calculates every stop at that country’s selected rate, then shows one suggested starting balance for the complete route.

Route Summary
3 CountriesAnything left stays in your NXTL account for another country or another trip.
The country changes. Your setup does not.
A single eSIM profile and a single prepaid balance follow you across borders. No second SIM to buy, no second app to install, and no leftover credit stranded at the frontier.
Before the first flight
Install NXTL through the app, My Account or the supplied QR instructions while you have Wi-Fi.
When the border is crossed
Your phone searches for a supported local network in the new country.
While data is used
Usage is charged at that country’s connected-network rate from the same prepaid balance.
After the trip
Keep the eSIM installed. Every unused amount stays ready without an expiration countdown.
Strong along the main route. Honest about the gaps.
Asia spans dense metro 5G markets and thinner rural or archipelago coverage in the same long-haul trip, so treat each country as its own network footprint. Registration rules, app restrictions and typical per-GB pricing also differ between sub-regions — Japan or Korea do not behave like a Gulf stopover or an ASEAN beach loop. Use country pages for live networks and rates; NXTL does not sell one blended Asia GB price.
Buy data for the trip you take — not the itinerary you guessed.
Fixed regional bundles force you to guess duration and data upfront. NXTL bills purely for actual megabytes used across each supported stop.
| The trip changes | NXTL pay-as-you-go | Fixed regional bundle |
|---|---|---|
| You add another supported country | Seamless Same eSIM and balance continue at that country’s rate | Coverage or package may need checking or replacing |
| You stay three extra days | No expiry Top up only if the balance actually runs low | Validity clock may expire first |
| You use less data than expected | Keep balance Unused money remains in the account | Unused bundle data normally expires with the package |
| You travel again months later | Reusable Reuse the installed eSIM and remaining balance | Usually buy a new validity-limited package |

Asia eSIM questions, answered before departure.
Clear facts on cross-border continuity, non-EU coverage, and how NXTL works alongside domestic EU roaming plans.
How is the Asia page different from the Southeast Asia page?
Southeast Asia focuses on the countries commonly combined on one overland or island-hopping loop (Thailand, Vietnam, Cambodia, Malaysia, Singapore, Indonesia, the Philippines, Laos). This page covers a wider set of Asian countries for itineraries that go beyond that loop — for example Japan, South Korea, the Indian subcontinent, or Central Asia.
Does one eSIM really cover such a large, varied region?
Coverage follows NXTL's active country list, shown on this page, rather than a blanket claim about the whole continent — check the included-country list for the specific countries on the planned itinerary.
Do local SIM registration rules vary a lot across Asia?
Yes — requirements range from a quick passport scan in some countries to more involved biometric or in-app verification in others. A data-only eSIM avoids that variation entirely, since it does not issue a local phone number in any of them.
Does the balance carry over between very different countries, like Japan and Nepal?
Yes — the same balance is used wherever NXTL has coverage; there is no separate account or separate top-up needed per country.
Is 5G available everywhere on an Asia itinerary?
No — 5G availability varies enormously across the continent, from mature, dense 5G markets to countries where 4G is still the primary technology. Each country's own page shows what is reliably known about its network technology rather than assuming 5G is universal.
Does the eSIM balance expire on a long, multi-month Asia trip?
No — the balance has no expiry date, so it survives a long, slow-travel itinerary across several countries just as well as a short multi-city trip.
