eSIM for business

If your team travels often, letting each person buy their own eSIM and claim it back usually ends in messy receipts and inconsistent plans. We take consolidated orders instead.

What the business service includes

• Multi-line orders in one go, with a traveller list.
• Quotations and receipts in the company name; whether a full tax invoice is possible depends on our registration status, so ask before ordering.
• Regional plans for trips crossing several countries.
• Installation guides in Thai and English you can forward to staff.

Who it fits

• Companies sending staff to meetings and trade shows abroad.
• Tour operators and agencies looking after whole groups.
• Production and event crews uploading large files on the road.

How this differs from everyone buying their own

There is nothing wrong with buying individually. If your team travels once or twice a year, that route is fast and self-contained. The friction starts when the headcount and the frequency go up: everyone picks a different plan, pays a different amount, keeps a different kind of receipt, and finance is left reconstructing afterwards which document covers what. Some are in a foreign currency, some are screenshots with no company name on them anywhere.

A consolidated order fixes that at one point: the whole team gets the same plan, paid through one channel, with one set of documents issued in the company's name. Everything downstream — installing on the handset, using it on the road — is unchanged, because the eSIM your staff install is the same profile any other customer receives. There is no special corporate edition of it.

The scope is worth stating up front. We take the order, issue the paperwork, deliver the profiles and help when something breaks after installation. We do not own networks abroad and we cannot instruct a local operator to treat one customer's traffic differently. If anyone tells you a corporate order gets you better signal, that is not true at a technical level.

Which teams actually get something out of it

The pattern we see most often is a group travelling at the same time, with one coordinator handling the paperwork — an executive assistant, someone in HR, or the team lead who signs off the expense anyway. The clearer that coordinator role is, the faster the whole thing moves, because nobody has to chase handset details from ten people one message at a time.

Tour operators and event agencies are the other group where it makes obvious sense, because the people who need data are not always your employees — they are guests, or freelancers assembled for that one job. Having the QR codes and a bilingual install guide ready in advance removes a lot of day-of work, since most trouble on departure day is not a signal problem at all. It is that nobody has installed anything yet.

The reverse is also true. If your people travel in a scattered way — different countries, different weeks, some staying for a month — one big order may not be the best answer, because each plan carries its own validity and starts counting according to the supplier's rules. Buying a large batch and holding it can mean some of it expires unused. When that is the situation, we will say so and suggest ordering in smaller waves instead.

From asking for a price to staff being online

1. 1Send us the trip outlineGive us the headcount, the countries, the dates, and a rough sense of the usage — daily video calls, or just maps and messaging. The first three are what we genuinely need; the last one lets us size the data allowance more sensibly.
2. 2We come back with options and pricingYou will usually see more than one route — country plans against a regional plan — with the trade-offs spelled out for your particular trip. What it costs depends on the plans chosen and on the supplier's terms at the time, so the figure is only firm once it is written into a quotation.
3. 3Confirm the list and check the handsetsBefore the quotation is finalised, you want to know that each handset supports eSIM and is not carrier-locked. Your team can check this themselves in advance, and it removes the single hardest problem to fix later.
4. 4Pay and receive the documentsThe profiles are ordered from the supplier once payment succeeds. Which documents we can issue depends on our registration status and on what your finance team needs, so ask before ordering whether the exact document you require is one we can produce.
5. 5Distribute to the travellersYou receive the QR codes and the install guide, then forward them through your own internal channel. Hand them out one code per person and record who got which, because a QR code can normally be installed only once.
6. 6Have everyone install before departure dayInstalling belongs at home or in the office while there is Wi-Fi, not at the airport. Switching the line on is a separate step that happens on arrival, and keeping the two apart is deliberate.

Quotations, invoices and the accounting side

The first thing a purchasing department asks is what paperwork we can issue. The honest answer is that it depends on two things: our own registration status, and the document formats your accounting system will accept. Some companies need a quotation before approval, some need an invoice separate from a receipt, and some need the seller's tax identification on every document.

So ask about documents before you order, not after you have paid. Asking takes a few minutes; re-issuing paperwork after the fact takes considerably longer, and once a transaction has been recorded it is sometimes not possible at all. Send the company name, address and tax number along with your pricing request and we can tell you straight away whether the document you need is one we can produce.

Choosing between country plans and a regional plan

This is not decided by the number of countries alone; it also depends on the shape of the trip. A team flying to one country and staying there is usually better served by a country plan. A team crossing three or four borders in a fortnight will find that swapping plans at every crossing creates more work than it saves — and it is the single most common source of confusion on a group trip.

Sizing data per person without guessing

The person buying is rarely the person using, which makes sizing hard. A better method than guessing is to ask the whole team the same three questions: how many hours a day of video calls, whether they will be uploading work, and how much turn-by-turn navigation they expect. Those three vary enormously in appetite, and they are the main reason two people on the same trip can consume wildly different amounts.

Always leave headroom for the things nobody plans: automatic app updates, photo backup to the cloud, and tethering a laptop when a file will not send. Those three are the most common reasons an allowance disappears faster than expected, and all three can be limited from the phone's own settings before departure.

Check the team's handsets before you order

The thing that derails a corporate order most often is not price — it is discovering that some staff handsets cannot use an eSIM at all. There are two usual causes: the model does not support it, or the phone was bought on a carrier contract and is still locked. Both are checkable before any money changes hands, and neither check is difficult.

The menu path differs by manufacturer and by OS version, so there is no single route that works on every phone. The general principle is to look for the section about mobile networks or SIMs and see whether an option to add a cellular plan or an eSIM exists. If no such option appears anywhere, treat it as unconfirmed and check the model against the device checker rather than assuming.

• Collect the brand, model and OS version of every handset on the team.
• Confirm each one supports eSIM before that person's name goes on the order.
• Ask anyone using a carrier-contract handset whether it has been unlocked.
• Have everyone install the profile while on a reliable Wi-Fi connection.
• Record which code belongs to whom and keep that file with the coordinator.
• Have a fallback for anyone whose phone will not work — a physical SIM, or tethering from a colleague.

Installing and handing over to staff

Once you have the codes, the remaining job is getting everyone to actually install before departure. What works is not leaving it purely to individual responsibility: set an internal deadline a couple of days before the flight and ask each person to confirm briefly that it is done. Chasing at that point is far cheaper than solving it once everyone is abroad.

In the instructions you forward, keep two things clearly apart: installing the profile, and switching it on at the destination. Plenty of people install and then immediately enable it while still at home, and with some plans that starts the clock. When validity begins is set by each supplier and stated on the plan page, so read that line before telling the team what to tap and when.

Watching usage during the trip

The next question is always whether the coordinator can see who has used what. The straight answer is that it depends on the supplier behind that plan. Some provide a balance page for the user to check; some do not, and no supplier guarantees that the figure updates in real time. When we quote, we will tell you plainly what kind of balance check the plan you are choosing comes with.

The method that always works, without waiting on the supplier, is having each person watch the data counter on their own handset in the cellular settings. That counter belongs to the phone rather than the network, so it will not match the operator's figure exactly, but it is a good early warning that someone is running out ahead of schedule. Resetting it at the start of the trip makes the number much easier to read.

When something breaks while the team is abroad

Route problems through one coordinator rather than having ten people message us in parallel with half the details each. In practice that is much faster, because it tells us immediately whether the fault hits one person or the whole group — the single most useful clue there is. One person usually means a settings issue on that handset; the whole group at once usually points at the network or the plan.

Send six things in the first message: the order number, who is affected, the handset brand, model and OS version, the country they are in right now, the network name the phone is showing, and a screenshot of the cellular settings screen. With all six we can usually answer in one round. With several missing we have to ask back, which costs another cycle while that person is still offline.

What we can commit to, and what we cannot

We can commit to replying around the clock, every day, to delivering the profiles once payment succeeds, to telling you plainly when a plan does not suit your trip, and to never recommending a more expensive plan without a reason we can explain. That is the part genuinely within our control.

What we cannot commit to is speed or coverage abroad, because the network belongs to the local operator. Reception inside buildings, in a basement conference room, or at a densely packed event is not something any eSIM seller controls. The channels we have are LINE, email, and phone at 089-942-0818 / 088-521-6848, and we take messages around the clock, every day.

If another seller promises a specific speed figure abroad, ask which operator they are making that promise on behalf of. The answer to that question is usually revealing.

Privacy of your staff's information

A team order means we receive details about people who did not contact us themselves — traveller names and the email addresses that receive the codes. We ask only for what delivery and support require, and we do not want things like passport numbers or individual card details. If any form requests those in our name, treat it as suspect and check with us first.

If your legal team needs specifics on what is stored and for how long, our privacy policy covers it separately and applies to business customers exactly as it does to individuals. Data held by the underlying supplier sits under that supplier's own terms and the law of the country it operates in, which is a separate set of rules from ours.

How to start

Send the rough itinerary, the headcount and what your finance team needs to esimonline.asia@gmail.com, or message LINE @esimonline at https://lin.ee/skDPoNx. If you do not have every detail yet, send what you have — we will only ask back for the pieces a real quotation genuinely needs.

If you would rather see the shape of the catalogue before talking to anyone, the plan listing is open to browse and the figures there are the ordinary prices any customer sees. Use them to sketch a budget before asking for a formal quotation.
