Regional destination
Southeast Asia eSIM
Southeast Asia's classic overland and island-hopping loop — Thailand, Cambodia, Vietnam, Malaysia, Singapore, Indonesia and the Philippines in various combinations — usually means a new tourist SIM at every border, and every one of those countries requires the same passport-and-biometric registration step at the point of sale. NXTL's eSIM is installed once and carries its balance across the whole loop, so a border crossing becomes a network change rather than a shopping errand. Rates are still set per country and network, shown live, rather than averaged into one regional figure.
Who this page is for
One eSIM for a multi-country Southeast Asia loop — Thailand into Vietnam or Cambodia, Malaysia into Singapore, island time in Indonesia or the Philippines — without a new local SIM registration at every border.
Backpackers and longer-stay travellers doing a multi-week regional loop, plus remote workers basing themselves in Bali, Chiang Mai or Ho Chi Minh City for a few weeks at a time and moving on to a neighbouring country afterwards.

Your estimate
Pay-as-you-go: there is no daily allowance or data cap. Estimates use each country’s current lowest per-GB rate; by default NXTL steers to the cheapest available network tier.
Border crossings
One balance across every border
A single top-up balance follows the loop from country to country, replacing what would otherwise be a separate tourist SIM, a separate passport check, and a separate leftover-data write-off at every border.

Pay-as-you-go vs bundles
What the rates mean for a regional trip
Rates vary noticeably within the region — archipelago logistics in Indonesia and the Philippines differ from the denser mainland networks in Thailand and Vietnam — so each country's own live rate table is the reference, not a single blended Southeast Asia price.
Regional fixed bundles
One price upfront, but the validity clock keeps running between countries — and unused gigabytes expire with it.
NXTL pay-as-you-go
Each country bills from the same balance at its own live rate. Travel slower or change plans — nothing is lost.
FAQ
Southeast Asia travel questions, answered
Coverage follows NXTL's active country list rather than a single "Southeast Asia" bundle — the included-country list on this page shows which of these countries currently have live pricing and network coverage, and the balance carries across all of them.
Yes, generally — island and archipelago geography means coverage on smaller or more remote islands is patchier than on the mainland or larger islands, regardless of which SIM or eSIM is used. Checking the specific island before relying on it for anything time-sensitive is worth doing.
No — NXTL is a data-only eSIM, so it does not issue a new local phone number and does not trigger the real-name registration process that Thailand, Vietnam, Indonesia, Malaysia and the Philippines each apply to local prepaid SIMs and phone numbers.
This page focuses specifically on the Southeast Asian countries commonly combined on one overland or island-hopping loop. The Asia region page covers a wider set of countries across the continent for longer, more varied itineraries.
No — the balance has no expiry date, so data left over from Thailand is still usable once the trip moves on to Vietnam or Indonesia.
Hotspot or tethering availability follows the device and the connected network's own rules rather than a separate NXTL restriction; most modern phones support sharing an eSIM's data connection.
