1

Choose your destination and plan

Read the data, validity, networks used and hotspot rules in each plan's spec table before you decide.

2

Pay and get the eSIM by email

We only order from the supplier after payment succeeds, then send the QR code and install steps to your inbox.

3

Install at home on Wi-Fi

Installation needs internet, so do it before you fly. Installing is not activating — the clock has not started yet.

4

Switch the line on when you land

Leave airplane mode, enable the eSIM line, set it as the data line, and keep roaming data off on your home SIM.

Why eSIMonline

We sell connectivity, not promises

Support around the clock

LINE, Messenger or the telephone, at any hour — whatever time zone you are in.

Full refund if it was never installed

Wrong plan, or a trip that changed? Ask for a refund within 14 days, as long as the profile was never installed.

eSIMs for 210+ destinations

A multi-country trip runs on one regional plan instead of a separate eSIM per border.

The real network, named before you pay

Every plan names the operator it rides in that country, whether hotspot works, and what happens when the quota runs out.

QR code by email the moment you pay

Install it at home before you fly, switch it on when you land — no hunting for airport Wi-Fi.

Pay by card or PromptPay

The price on the page is the price you pay. No hidden fees, and the charge runs on Stripe.

VISAmastercardJCBAMEXUnionPayPromptPay

Payments run on Stripe, and this site never stores your card number. Apple Pay and Google Pay appear on their own when your device and browser support them.

Plan types

Four genuinely different shapes, and the catch in each

TypeSuitsWatch out for
Fixed GBShort to medium trips where you know your usageUnused data expires with the plan
DailyLong trips or steady daily useFull-speed data resets daily and does not carry over
無制限Travellers who do not want to count gigabytesThere is a daily full-speed ceiling; past it you are throttled under FUP
RegionalItineraries that cross several countriesHigher price per GB than single-country plans, with some territories excluded
Calculator

How many gigabytes does this trip need?

Computed from how you use data, not from the plan we would like to sell.

8 GB

About 0.9 GB a day over 7 days, plus 15% headroom for the heavier days.

This is an estimate from typical usage patterns, not a measurement of your phone. For a real number, check the data usage stats from your last trip.

How we make money, and where this data comes from

Our revenue comes only from the margin on the plans we sell ourselves. We have no commission and no affiliate links. We do not take payment to change rankings or recommendations, and we never mark a plan as best because it pays us more.

よくある質問

The questions we are asked most

What is an eSIM and how does it differ from a normal SIM?+

An eSIM is a SIM profile installed straight onto a chip inside the phone. There is no plastic card, so you can buy and install before you travel and keep your existing SIM in place.

When does the validity start?+

Most plans start on first connection at the destination rather than at purchase, though some start at purchase. Each plan's spec table states which.

Do I keep my own number?+

Yes. A travel eSIM is a separate data line; your home SIM stays in the phone and still receives calls and bank OTPs. Just switch its roaming data off.

Does my phone support eSIM?+

Dial *#06# and look for an EID line. You can also search your model in our device checker, though what the handset itself reports is the most reliable answer.

How far ahead should I buy?+

For plans that start on first connection you can buy whenever, but install one to two days before the flight so there is time to fix any problem.

What if installation fails?+

Message us with your order number, handset model and a screenshot of the cellular settings. Do not delete the profile — it installs only once.

Can I share a hotspot?+

Only on plans that say so, and we show it in every spec table. Some plans, especially cheap unlimited ones, restrict or forbid it.

Is there a phone number and SMS?+

Most plans are data-only with no number for SMS. If you need Thai bank OTPs, keep your home SIM in the phone with that line enabled.

What speeds should I expect?+

It depends on the networks the plan uses and local congestion. We do not guarantee a speed figure, and we do not publish test results we did not run.

Can prices show in another currency?+

Yes, from the header. Prices are held in USD and converted for display; the amount actually charged depends on the payment provider and your bank.

Can I top up?+

Only on plans marked as top-up capable. If yours is not, buy another plan and install it as a second profile on the same phone.

When can I get a refund?+

The refund policy sets it out: broadly, when a plan does not work as described and cannot be fixed. Plans already activated and used generally cannot be refunded.
