How quickly will support reply?

We take messages 24 hours a day, every day, as stated at the foot of every page. Daytime in Thailand is quickest and the small hours can be a little slower. To get to a fix fastest, include the order number, device model, the country you are in, and a screenshot of the problem in your first message.

Asking how quickly you will get a reply is a completely reasonable question, especially when you are standing at an airport or have just landed and the connection is not doing what you expected. Wanting an answer immediately is normal. This page exists to be straightforward about that rather than to promise something we cannot keep. We would rather you know how contacting us actually works before you travel, so you can time things correctly from the start.

The most important starting point is that we take messages around the clock, every day, whatever time zone you are in — something arriving at three in the morning is still read. What we will not claim is that every answer lands within the same few minutes, because speed genuinely depends on the hour and on how complex the case is. What we can promise is that nothing is left sitting until morning.

What our support hours actually mean

The hours shown at the foot of the site are the window during which a real person is reading and answering messages, not simply when the system is running. The ordering and eSIM-issuing systems work automatically at any hour of the day regardless. But answering questions, reviewing a specific case, and deciding on a refund or an edge case all need a person to look at it, which is why those are limited to the stated window.

Outside that window, your message does not vanish; it sits in the queue until the next support window opens. What is worth doing while it waits is putting every relevant detail in that first message, so the exchange does not turn into several rounds of back-and-forth, which only pushes the final answer further out.

Around the clock, but not at one single speed

Our customers are spread across time zones, so we take messages at any hour. But keeping the quality of an answer good requires people who genuinely understand the product and the systems behind it, not just someone tapping replies at a screen. The things that can be settled immediately — resending a QR code, walking through the install steps — happen at any hour. A case needing a deeper look, such as a refund or a question put to a supplier, can take longer late at night Thailand time. We would rather say so than leave you guessing.

How you can reach us: LINE, Messenger, email and the telephone

Our channels are LINE at @esimonline via https://lin.ee/skDPoNx, Messenger, email at esimonline.asia@gmail.com, and the telephone on 089-942-0818 or 088-521-6848. All of them are watched by real people around the clock; the only difference is how quickly a message tends to be noticed, which follows how each channel is normally used.

What to include in your first message to get to a fix fastest

A first message with complete detail is worth more than a quick line saying the internet isn't working, followed by waiting while we ask for one thing at a time. Every round of asking back adds real waiting time, not just a feeling of it. Including the order number, device model with its OS version, the country you are currently in, and a screenshot of the symptom, all together from the start, lets the team see the full picture immediately without guessing.

If the order number isn't on hand, mentioning the email or phone number used at checkout works as a substitute, and roughly recalling the purchase date helps too. What is worth avoiding is a bare it isn't working message followed by waiting for us to ask one question at a time, since every round of that eats into the support window unnecessarily.

• Order number, or the email/phone used at checkout
• Device model and OS version
• The country you are currently in
• A screenshot of the exact symptom
• What you have already tried before contacting us
• When the symptom started, in local time or with the time zone made clear

What makes a screenshot actually useful

A genuinely helpful screenshot shows the alert message or the full screen, not one cropped down to a small fragment. Sometimes details that look unimportant, such as the status bar showing a network name or signal, turn out to be the exact clue that helps make sense of the symptom faster.

Time zones while you're travelling

The hours shown at the foot of the site are our team's own local time, not the time in whichever country you happen to be in. If you are far from that time zone, the moment you find it convenient to write might not line up with when someone is actually reading. Knowing this ahead of time avoids the surprise of wondering why a message sent late at night where you are hasn't been answered instantly.

When describing when a symptom happened, stating your local time along with the time zone or country reduces confusion, rather than giving just a bare number, which is easy to misread as a different time zone entirely.

What happens after you send a message

Messages are not answered in a random order; they go through a rough set of steps that keeps every case reviewed systematically, even though the time each one takes differs, since cases vary in complexity. Some can be answered straight from the details already provided; others need a check with a supplier or a bank first before a clear answer is possible.

1. 1Message enters the queueWhatever comes in via LINE or email is logged in the order it arrives.
2. 2Initial details get reviewedThe team reads the message and checks whether the details provided are enough to investigate.
3. 3The case gets checked properly if neededSome cases need the order status pulled, a check with a supplier, or a wait on a bank's own response before an answer is possible.
4. 4A reply goes backThe reply states what was found and the next step, if any.
5. 5Follow-up if it isn't resolved yetIf it still needs an outside answer, the team follows up once there is something new to report.

Urgent vs non-urgent cases — plan for this before you fly

Not every case carries the same urgency. Something tied to right-now use, such as failing to install after you have already landed, differs from a general question asked well before buying. The catch is that a case's urgency doesn't automatically pull the answer forward, since the support window is still the main constraint.

The practical approach is finishing everything that can be done ahead of time before you travel: confirming the device supports eSIM, buying the plan several days in advance, and installing the profile while there is still Wi-Fi at home or at the office, rather than leaving all of it for the airport or after arrival, when every problem suddenly feels urgent at once.

What we can't speed up

Some steps sit outside our authority no matter how much we want to answer faster: a card-issuing bank's approval, a payment channel provider's own processing, or profile issuance from a network supplier's side. All of these belong to someone else's system that we have no way to accelerate or skip on your behalf.

If a reply takes longer than expected

If the wait feels unusually long, sending a single follow-up asking for a status update is entirely normal and not seen as a bother. But opening several separate threads about the same issue, or resending the same message repeatedly in a short span, makes it harder to keep the original answer connected, since the team then has to spend time working out which message belongs to which case.

Preparing before you travel to reduce problems that need support

A number of problems that seem to need waiting on a support reply can actually be avoided ahead of time by checking things thoroughly before travel — using the device compatibility checker, and reading through the installation steps before reaching the airport, genuinely cuts down how often you need to lean on support while you're on the move.

When to use LINE, when to use email

If the symptom needs a screenshot and you want a quick back-and-forth, LINE is usually more convenient, since its chat format makes attaching images and typing follow-ups easy. If it involves several attached documents, or you want a written record to refer back to later, email suits it better. Whichever channel you pick, complete detail in the first message still matters most.
