Which payment methods do you accept?

Author: eSIMonline Editorial · eSIMonline editorial teamSenast uppdaterad: 5 september 2026
Which payment methods do you accept?

The live list appears at checkout and depends on the connected gateway. Our system supports credit and debit cards plus local methods such as PromptPay, Apple Pay and Google Pay when the connected gateway offers them.

The exact list of payment methods you see is set by whichever payment gateway is connected at the time you check out, which is why the short answer points you to the checkout page itself rather than a fixed list here. What we can describe reliably is the categories of payment our system is built to support, how each one generally behaves, and what to check if a payment does not go through the way you expected.

It suits anyone about to check out and wanting to know what to expect, anyone whose card or wallet has been declined and is not sure why, and anyone who wants a receipt for expense reporting after the purchase. Nothing here names a specific bank, card network fee, or exact processing time, since those details sit with the connected gateway and can change without us controlling them directly.

Why the exact list only lives at checkout

Payment gateways are the systems that actually process a card or wallet payment on our behalf, and which one is active, along with which methods it currently supports, is a setting on our side that can be adjusted over time. Publishing a fixed list on this page would risk it going out of date the moment that setting changes, which is why the checkout page itself is the source that always matches what is live.

In practice this means the safest habit is checking the checkout page itself each time you buy, rather than assuming last month's options are still exactly the same today. Most of the time the core categories stay stable, but which specific wallet or local method is switched on can shift as gateways are updated.

Credit and debit card payments

Card payment is generally the most consistently available category across the checkout options, since most connected gateways are built to accept the major card networks by default. A card payment usually asks for the card number, expiry date, security code, and sometimes a billing address, following the same familiar pattern as most other online card checkouts.

We do not maintain a list of every card network or issuing bank that works, since acceptance ultimately depends on the connected gateway and, in some cases, on restrictions your own bank places on international or online transactions. If a specific card fails, that is worth checking with your bank directly, alongside the troubleshooting steps later on this page.

Local methods such as PromptPay

Local payment methods like PromptPay are offered when the connected gateway supports them, and they typically work through scanning a QR code or confirming a payment inside your own banking app, rather than entering card details on our checkout page. This suits anyone who prefers not to type card numbers online, or who does not have an internationally accepted card handy.

Whether this option appears depends entirely on the connected gateway at the time, so it is not something we can promise will always be visible. If it is important to you, checking the checkout page before committing to a purchase is the only reliable way to confirm it is currently on.

Digital wallets such as Apple Pay and Google Pay

Where the connected gateway offers them, Apple Pay and Google Pay let you confirm a payment using the card already stored on your device, through the phone's own authentication method, rather than typing card details manually. This tends to be the fastest checkout option when it is available, since most of the card entry has already been done on your device beforehand.

These wallets rely on the card already being set up correctly on your device, so if a payment through one of them fails, it is worth checking the card stored in the wallet itself, separately from anything on our checkout page. Availability again depends on the connected gateway, so the same rule as the other methods applies: check the checkout page directly for the current state.

The currency and amount shown at checkout

The amount displayed at checkout is the figure that applies to your purchase; if your card or wallet bills in a different currency, any conversion happens on your card issuer's or wallet provider's side, following whatever rate and process they apply, not something set by us. We do not publish a conversion rate or state whether a conversion fee applies, since that detail belongs entirely to your own card issuer.

If the exact amount that will appear on your card statement matters to you, checking with your card issuer about how they handle foreign currency transactions before you buy is the more reliable route than guessing based on the checkout total alone.

What happens after you pay

Once a payment is confirmed, an order confirmation is generated and the eSIM profile tied to your purchase is issued, ready to be installed following the site's own install guide. Exactly how fast that confirmation and profile appear can vary slightly depending on the payment method used and how quickly the gateway confirms the transaction back to our system.

Keep the order confirmation and its order number, since that number is what identifies your purchase if you ever need to contact the team about an issue with the profile itself, separately from anything to do with how the payment was made.

If a payment fails or is declined

A declined card is most often something the gateway or the card issuer flagged, rather than a problem on our checkout page itself, since we do not decide which individual transactions get approved. Common, generic reasons include insufficient funds, a card issuer blocking an unfamiliar or international-looking charge as a precaution, or a mistyped card number or expiry date.

If a card keeps failing, trying a different payment method at checkout, if one is available, is usually faster than repeatedly retrying the same card. If every method fails, or the same card is declined everywhere else too, contacting your card issuer directly is the next step, since only they can see the actual reason the charge was blocked.

Refunds and cancellations

Refund eligibility follows the site's published refund terms rather than anything specific to the payment method used to buy. Broadly, whether a refund applies depends on things like whether the profile was installed or activated yet, so the payment method itself is rarely the deciding factor in whether a refund is possible.

When a refund is issued, it returns to the same method used for the original payment, since that is how most gateways process a reversal. How long it then takes to show up on your own statement is controlled by your card issuer or wallet provider, usually 5 to 10 working days.

Payment security

Card and wallet details are handled by the connected payment gateway during checkout, rather than being stored directly on our own system in a way we could see or retrieve. This is standard practice for how most online checkouts are built, separating the party selling a product from the party actually processing card data.

We do not state a specific certification, standard, or test result here, since those belong to the gateway itself and can vary by provider. If you want detail on a specific gateway's own security practices, that is a question best directed to the gateway shown at checkout, or to us via the contact channels below if you are unsure who to ask.

Paying again for a second person or device

Each eSIM purchase is its own separate transaction and its own separate profile, so buying for a second traveller or a second device simply means going through checkout again, choosing the same or a different payment method as before. There is no bundled multi-device checkout that changes how payment works; the payment step itself stays the same each time.

If you are buying for several people at once, it is worth double-checking each order confirmation carries the correct traveller's details before moving on to the next purchase, since payment method choice has no bearing on which profile ends up going to which person.

If you do not see the method you were hoping for

If a payment method you expected, such as a particular wallet or local option, does not appear at checkout, the most likely explanation is that the currently connected gateway simply does not currently offer it, rather than anything wrong with your account or device. This can also shift over time as gateways change, so a method missing today does not necessarily mean it will always be missing.

In that case, the practical options are using one of the methods currently shown, or reaching out to the team to ask whether the method you want is likely to return, though we cannot promise a timeline for any specific gateway change.

Receipts and invoices for expense claims

The order confirmation generated after a successful payment serves as your record of the purchase, showing the amount charged and the order number tied to it. This is generally enough for a straightforward expense claim, though the exact format your employer or accounting team requires can vary.

If a different document format is needed, such as a formal tax invoice with specific fields, contact the team with the order number so the request can be looked at directly, rather than assuming a particular format is or is not available without asking first.

The categories described here — cards, local methods, digital wallets — are what our system is built to support; the live list you actually see depends on the gateway connected at the moment you check out.
Do not assume a payment method available last time you bought a plan is still available today — check the checkout page each time, since the connected gateway and its supported methods can change.
Do not enter card details anywhere other than the site's own checkout page or an official wallet prompt on your device. We never ask for full card details over LINE or email.
  • Have the card or wallet you plan to use ready before starting checkout
  • Confirm the card has international or online transactions enabled if needed
  • Check the amount and currency shown before confirming
  • Keep the order confirmation and order number after a successful payment
  • If a specific tax invoice format is needed, contact the team in advance

Vanliga frågor

How do I know which methods are actually available right now?+

Check the checkout page while you are buying — the list shown there is what the currently connected gateway actually supports at that moment.

Why was my card declined even though there is enough balance?+

It may be that the card issuer blocked what looked like an international transaction as a precaution. Contact the issuer directly to confirm, or try a different payment method if one is offered.

Which method does a refund get returned to?+

Refunds generally return to the same method used for the original payment. How long it then takes to show on your statement depends on your own card issuer or wallet provider.

Do I need to send card details to the team via LINE or email if there's a problem?+

No, and you should not. We never ask for full card details through those channels. If there is a payment problem, just send the order number and a description of what happened.

What do I need to do if I want a tax invoice?+

Contact the team via LINE at https://lin.ee/skDPoNx (@esimonline) or email at esimonline.asia@gmail.com with the order number and the document format you need.
