I ordered with the wrong email address. What now?

Contact us with the order number, the address actually used, and the correct one. We verify that you are the order's owner before sending installation details to the new address; that check exists so activation data never reaches the wrong person.

This one always seems to surface at the worst possible moment: right after the order confirmation button has already been pressed, it becomes clear that one character in the email address was mistyped, or a saved autofill address slipped in without being noticed, or worse, someone else's address got typed in while rushing at the check-in counter. The question that follows immediately is who exactly is about to receive the QR code and activation string for this order, and what to do if it is not actually you.

This page covers why the order's email address cannot simply be edited by yourself inside the system, what information needs to be ready before contacting the team, the difference between a small typo and typing in someone else's address entirely, and what happens if the profile has already been opened at the wrong address before you managed to reach anyone.

Why identity has to be verified before the order's email changes

A QR code and its activation string are the key that opens the profile on a device the instant anyone scans it or types the string in. Whoever is holding that link or file can install it in place of the actual buyer, whether on purpose or not. That is exactly why the destination email on an order cannot be changed without any check at all — if anyone could edit it by quoting only the order number, an unrelated person could just as easily impersonate the buyer and redirect delivery to their own inbox.

Verifying identity before anything is sent to a new address protects both sides at once: the actual buyer, who has no reason to let someone else use a plan they paid for, and the owner of whichever inbox was typed in by mistake, who has nothing to do with this order at all. The check is not needless friction; it is the safeguard this exact situation genuinely calls for.

The three pieces of information worth having ready before contacting the team

The first is the order number, which pins down exactly which order is being discussed. The second is the address that was actually typed at the moment of purchase; even knowing it was wrong, it still needs stating precisely what was typed, since that lets the team match it against what the system actually recorded. The third is the correct address the installation details should be sent to instead.

Optional details that are not required but can speed the check along are the rough date and time of purchase and the payment method used, if remembered. Device model or operating system is not really needed for this particular issue, since the problem sits at the email destination, not on the device itself, so there is no need to dig that up before reaching out if it is not on hand.

What happens once the issue has been reported

1. 1Gather the order number and both email addresses involvedHave the address mistakenly typed at checkout and the correct one to redirect to ready before making contact.
2. 2Reach out via the team's LINE or emailState all the details in a single message so there is no need for several rounds of back-and-forth.
3. 3Wait for confirmation that you are the actual order ownerThe check is based on matching order details, never on asking for a password or any card information.
4. 4Receive the installation details at the new addressOnce identity is confirmed, the QR and activation string are sent to the correct address instead.
5. 5Check both the inbox and spam folder of the new addressMail from a sender you have not received from before can sometimes land in spam on the first contact.

A small typo versus typing in someone else's address entirely

If it is only a one- or two-character typo in your own address, such as a swapped domain or a dropped letter, the risk is far lower, since that inbox may not even exist, meaning the mail simply bounces and nobody unintended ever receives it. In that case, simply supplying the correct address for the team to resend to is enough.

But if it is a real, existing mailbox belonging to someone else, say a travel companion's address typed into the wrong field, or an old work address someone else now reads, urgency rises sharply, because there is a genuine chance that person opens the mail and installs the profile before you manage to reach the team at all. Contact should happen the moment the mistake is noticed, without waiting.

If the profile has already been installed at the wrong address

An eSIM profile is generally a one-time install per profile. Once the QR code or activation string has been used on any device, that profile is bound to that device and typically cannot be reissued again. That is exactly why reaching out immediately upon suspecting a wrong email matters — before anyone has had the chance to install it first.

If it turns out the profile really has been installed, the way forward depends on the order's status and the case-by-case policy that applies, which varies by situation — there is no single fixed answer that covers every case. What matters is reporting every detail described above to the team and letting them assess the most appropriate path for that specific situation.

The order's email is not always the same thing as the account you are logged into

If this order was placed through an account that is logged in, the order page in that account may still list the purchase normally, even though the destination address the installation details were sent to was mistyped, since the account and the delivery address can be separate fields at certain steps of checkout. It is worth checking the account's order page first before concluding the information has vanished entirely.

But if the order was placed without an account, or as a guest, the address typed at that moment is the only reference the system holds for that order, so correcting it has to go through contacting the team directly — there is no self-service way to reach the original details through an account page.

Why there is no self-service "edit email" button on the order page

The reasoning matches what was explained earlier about verifying identity: if editing were open to anyone simply landing on the order page, then anyone who happens to know the order number, which could be visible on a receipt or a notification that reached the wrong hands, could just as easily redirect delivery to their own address. Having the team check every time is the only way that gap gets closed.

It can feel like extra time compared to a one-click self-fix, but in a case where the wrong address genuinely belongs to someone else, this step is exactly what stops the information landing in unrelated hands — a trade worth making every time.

Getting ready before contacting speeds things up

Before sending a message to the team, it helps to go back and look at the payment confirmation screen or the receipt received at the time of purchase. A saved screenshot confirms precisely what was typed at that moment, rather than relying on memory alone, which can occasionally be wrong too.

If the payment method used is remembered, such as which card or which transfer channel, mentioning it too helps the team locate the matching order faster, in case the order number itself cannot be found or is not remembered with certainty.

Preventing this from happening again next time

The single most common slip is the email field being autofilled by the browser from an old address that may no longer be in active use. Before confirming any order, it is worth reading that autofilled field back once more to make sure it is genuinely the right one.

If ordering in a rush, say at the airport or mid-queue, typing the address in by hand rather than letting the system autofill it takes a little longer but meaningfully cuts the risk of a typo or the wrong address being used at all.

Common mistakes made during this process

The first mistake is waiting too long to reach out, on the assumption it can be sorted later, when in fact the longer it sits, the higher the chance someone else opens that mail and installs the profile first, particularly if the mistyped address belongs to a real, active person.

The second mistake is attempting to log into someone else's mailbox to delete the message yourself, which should never be attempted, both for security reasons and because there is no genuine way into someone else's inbox in the first place. The correct route is having the team act on it instead.

Privacy during the verification check

The information supplied during this check, such as the order number and both email addresses, is used solely to confirm that you are genuinely the order's owner. The team never asks for an account password, card details, or any OTP code during this verification. If anyone claiming to be the team asks for information like that, treat it with suspicion straight away.

If unsure which channel to use to get in touch

Both channels handle this the same way — the difference is only in communication style. LINE at https://lin.ee/skDPoNx (@esimonline) suits short back-and-forth typing and makes attaching a screenshot easy. Email at esimonline.asia@gmail.com suits laying out a longer explanation in one message with a clear written record kept.

Pick whichever channel is more convenient; neither one is inherently faster to get a reply from. What actually speeds a case along is how complete the information is in that first message, not which channel was chosen to send it through.

If the wrong email is also tied to a membership account

If the order was placed through a membership account that was itself registered with the wrong email from the start, not merely a typo made while filling in where this order's details should go, the situation runs deeper than fixing a single order's destination, since it may involve access to the whole account over the long run, not only the one order being discussed here.

In that case, it is worth stating clearly in the first message that the problem sits at the whole account's email, not just this one order's, so it can be checked and corrected fully from the outset, rather than fixing only this single order and running into the same issue again with the next purchase.

What to have ready before making contact

• The order number for the purchase in question
• The address actually typed at checkout, even knowing it was wrong
• The correct address the details should be sent to instead
• A screenshot of the receipt or payment confirmation, if one was saved
• The rough date and time, and the payment method used, if remembered
