eSIM for business travel: land connected, expense it cleanly

Last updated: September 7, 2026

The expensive version of a business trip goes like this: you land, your phone finds a partner network, and your company's roaming add-on quietly starts billing by the day, or by the megabyte if nobody set one up. The cheap version is an eSIM for business travel that you bought at your desk the day before: a fixed price, installed before the flight, live the moment you switch it on in the arrivals hall.

This guide is written for the person who travels for work and files their own expenses, not for a procurement department. What to buy for a two-day trip versus a two-week one, how to keep your work number ringing, what the receipt looks like, how to buy for a whole delegation in one order, and where a travel eSIM sits with your IT department's rules. We sell eSIMs, so read the recommendations with that in mind.

The first hour decides whether the trip is smooth

Meetings don't wait for you to find a SIM kiosk. Everything you need in the first hour is data: the ride-hailing app, the hotel address, the calendar invite with the room number, the message to the client saying you've landed. A plan installed at home covers all of it before you've cleared passport control. No app to download, no shop, no contract.

It also breaks the airport Wi-Fi habit. Shared networks in lounges and hotels are the classic place to leak company data. A dedicated mobile connection is simply the safer default, and your corporate VPN sits on top of it exactly as it would at home.

How much data a work trip actually uses

Business use is predictable in a way holidays aren't. Email, chat, maps, a boarding pass and a few documents barely register. Two things eat data: video calls, at roughly half a gigabyte to a gigabyte an hour, and tethering a laptop, which turns every background sync into mobile data.

Round up. The gap between a 5 GB and a 10 GB plan is a few dollars. The gap between having data and not having it during a client demo is your afternoon.

The general version of this maths is in how much data you need for travel.

Which plan for which trip

One city: buy the country plan. In most business hubs 1 GB for 7 days costs 2 to 5 US dollars, 3 GB for 30 days about 5 to 10, and 10 GB for 30 days 11 to 21, with the US and the UAE at the top of those ranges. A week of heavy video calls is where you have to read the fine print on unlimited: our standard Unlimited plan gives 1 GB a day at full speed and then slows to 1.25 Mbps, which is fine for messaging and hopeless for calls. For camera-on days look at Unlimited Plus, which pools 6 GB of full-speed data for every day of validity and comes in 5, 10 and 15-day lengths for most of Europe plus Australia and New Zealand.

Several cities in one trip: a regional plan means one install and one receipt. Europe covers more than 30 countries including the UK and Switzerland; there are Asia, Middle East and Americas plans, and a Global plan for the itinerary that touches three continents in a fortnight. Regional data costs more per gigabyte, but for a Frankfurt-Zurich-London week the convenience is worth the difference, and the expense report has a single line.

The regional plans, on their own pages: Europe, Asia, the Middle East, the Americas and Global.

What it costs, roughly

Prices move with exchange rates and with what our supplier charges us, so treat this as the shape of things and check the live price before you buy. As of September 2026, in US dollars, for the hubs people fly to most:

For scale: a five-day trip to London on a 3 GB plan is about five dollars. The same trip on a typical carrier roaming pass runs around ten dollars a day, and the pay-as-you-go rates that apply when nobody set a pass up are in a different league. Even the US, our most expensive hub, comes to about 19 dollars for a full 10 GB month.

Receipts and expense claims

Every order sends a confirmation email that names the plan, the quantity and the amount paid, and your account keeps a list of orders with the date and amount. For most expense systems that's the whole claim: forward the email or upload a screenshot, add the trip and the purpose, done. If your finance team needs a document in a particular format, email esim@alodata.net and we'll sort it out; we reply within one business day.

Two habits make it cleaner. Pay with the card you expense from, so the statement line matches the email. And buy before you travel rather than from the hotel: the email lands while you're still at your desk, and the plan doesn't start counting down until you first use it at the destination, so nothing is lost by buying early.

Buying for a team or a delegation

You can put up to 25 eSIMs in one order. Each comes with its own numbered QR code in the same confirmation email, so the person organising a trade-fair team or a board visit buys once, forwards each QR to its traveller, and files one receipt. Everyone installs at home on Wi-Fi. Nobody queues at the airport.

One thing to tell the team a week ahead, not at the gate: their phones must be unlocked and eSIM-capable. Dial *#06#; an EID on the screen means the phone can take an eSIM. If the company issues locked or heavily managed devices, that's a conversation with IT first.

The full list of phones is in our device compatibility guide.

What your IT department will ask

Three questions come up. Does the eSIM touch company data? No: it's a data pipe like any SIM; your device management, VPN and policies keep working on top of it. Can a managed phone even add an eSIM? Sometimes not: supervised iPhones and some Android work profiles block adding a mobile plan, so test on your own phone at your desk before the trip. Does it replace the corporate roaming plan? For data, yes; your work SIM stays in the phone for calls and texts on your usual number, with its data roaming switched off so the company plan isn't billed as well.

Keep the VPN on when you touch company systems, exactly as you would on hotel Wi-Fi. The eSIM makes the connection private to you; the VPN makes it private to your company.

Your work number keeps ringing

On a dual-SIM phone both lines stay registered. Set the eSIM as your mobile data line and leave the work SIM on for calls and texts, so clients and colleagues reach the number they have and the codes for your bank and company logins still arrive. Turn data roaming off on the work SIM. Incoming calls abroad may still cost on the company plan; that's a policy question for whoever owns the contract, not something the eSIM changes.

The exact settings for iPhone and Android are in our dual-SIM guide.

The night-before checklist

1. Check the phone is unlocked and eSIM-capable: dial *#06# and look for an EID. On a company phone, check with IT that adding a plan is allowed.
2. Buy the plan for the trip length and the destination, or a regional plan for a multi-city itinerary.
3. Install from the QR code in the email, on Wi-Fi, and label the line 'Work trip data'. Installing doesn't start the clock; validity begins the first time the eSIM uses data at the destination.
4. Set it as the mobile data line, leave its data roaming off until you land, and switch data roaming off on the work SIM.
5. On iPhone, turn off Wi-Fi Assist so a weak office Wi-Fi signal can't start the plan a day early.
6. Forward the confirmation email to your expenses inbox while you think of it.

Two guides worth having open at the gate: how to install and activate an eSIM and what to do when an eSIM will not connect.

If the trip is cancelled

A plan you bought and never installed is fully refundable within 30 days. Once it's installed and activated it isn't, because the service has been delivered. Trips move; buy when the flight is booked, install when it's certain.

The details are in our refund policy.

Notes on the hubs

United States

Our priciest hub per gigabyte, as it is for the locals. Coverage in the cities is excellent. If your own phone came from a US carrier on a contract, make sure it's unlocked before you count on adding a plan anywhere. United States eSIM plans

United Kingdom

Cheap and well covered: a 3 GB plan handles a normal working week. The UK sits outside the EU roaming rules, so a European regional plan only helps here if the UK is on its list. Ours is. United Kingdom eSIM plans

Germany

Trade-fair country. Exhibition halls and conference centres are exactly where a personal connection beats the venue Wi-Fi. Unlimited Plus is offered for 5, 10 and 15 days if your week is wall-to-wall video. Germany eSIM plans

United Arab Emirates

Dubai is a transit hub as much as a destination, and the UAE is one of our pricier countries. Calling apps such as WhatsApp and FaceTime are blocked on UAE networks; a travel eSIM that routes its traffic abroad is what keeps them working. Test it before the client call rather than during.

Singapore

Excellent coverage and cheap plans, and the regional Asia plan includes Singapore along with Malaysia, Indonesia and Hong Kong, so a Singapore-Kuala Lumpur-Jakarta week runs on one line. Singapore eSIM plans
