Short answer: A corporate travel eSIM lets a travel management company (TMC) or in-house travel desk issue mobile data to every business traveller alongside the flight and hotel, delivered instantly as a QR code or one-tap install link. Through the eSIM Signal partner programme you buy at a partner price, set your own price to clients, and order through the Business Panel or the REST API, with no setup fee, monthly minimum or contract.
Corporate roaming is one of the last unmanaged costs on a business trip. Flights, hotels and rail sit inside policy and booking tools, but the traveller's phone bill arrives weeks later on a different budget line. This guide explains how a TMC can close that gap, step by step.
Why corporate travel eSIM fits travel management companies
Business travellers need data the moment they land: the ride-hailing app, the VPN authenticator prompt, the Teams call from the taxi. Corporate roaming bundles vary by country and often leave travellers rationing data or claiming it back on expenses.
A TMC is in a strong position to fix that, because it already knows who is travelling, where, and for how long. That is exactly the information needed to issue the right eSIM.
For the TMC, it adds:
- A new service line priced and branded by you, not a commission on someone else's product
- A differentiator in RFPs and account reviews, where clients increasingly ask how you help with traveller connectivity and duty of care
- Fewer expense claims for your clients' finance teams, because data is booked and billed like any other trip component
- A reason to contact the traveller before departure, which is also the moment to confirm itinerary details
If you also serve leisure customers, our guide to eSIM for travel agencies and tour operators covers the holiday side. Corporate travel is different: repeat travellers, policy, cost centres and invoices.
Three ways to deliver eSIMs to business travellers
1. Issued by agents from the Business Panel
Consultants order an eSIM in the Business Panel while handling the booking, and the ICCID, activation code, QR code and install link appear straight away. No development work is needed, so it suits a pilot with one or two clients.
2. Built into your booking flow with the API
If you run your own online booking tool, mid-office or traveller app, connect it to the REST API at https://esimsignal.com/api/v1. When a trip is ticketed, your system places the order and adds the install link to the itinerary email or app. Our eSIM reseller API integration guide walks through authentication, ordering and webhooks in detail.
3. Pre-ordered for a client's travel desk
Some corporate clients prefer to hold a small stock of eSIMs for last-minute trips. Agents order in the panel, hand the install links to the client's travel coordinator, and any eSIM that is never installed can be refunded to your balance within the refund window.
How it works, step by step
- Apply for a partner account. Submit the form at apply for a partner account. The team reviews every application, and most partners go from first contact to first sale within a few days.
- Fund your prepaid balance. Top up by card, save the card, set a low-balance alert and, if you like, turn on automatic top-up so a busy Monday never stops ticketing.
- Set your retail price. Every package has a partner price that applies automatically to every order. You decide what your clients pay, whether that is a per-trip fee, a markup or part of a managed-travel bundle.
- Map your top routes. Pull the price list (searchable, filterable and downloadable as a spreadsheet) and match packages to your clients' most frequent destinations, such as London, Frankfurt, New York, Singapore or Dubai.
- Issue, deliver, support. Each order returns the ICCID, activation code, QR code and one-tap install link instantly. Your team handles first-line questions; your named account manager helps with anything platform-related.
Platform features that matter for corporate travel
Cost-centre and trip references
Every API order accepts a customer_ref. Put the booking reference, traveller ID or cost-centre code there and it follows the eSIM through your reporting. Combined with the itemised ledger and its CSV/Excel exports, finance teams can reconcile eSIM spend per client, department or trip without manual matching. Receipts are available for every ledger entry.
Webhooks for itinerary updates
Signed webhooks tell your system what happened without polling: order.completed, order.failed, order.refunded, esim.activated and esim.expired. Verify each one with the HMAC-SHA256 signature in the X-ESIMSIGNAL-Signature header. A common pattern is to mark the trip "connectivity ready" when esim.activated arrives, and to prompt the traveller with a reminder if it has not arrived by departure day.
Top-ups for trips that run long
Business trips get extended. Use GET /esims/{iccid}/topups to list the add-ons available for an eSIM and POST /esims/{iccid}/topup to apply one, so the traveller keeps the same eSIM rather than installing a second one.
Safe retries and security
Send an Idempotency-Key with each order so a timeout in your booking tool never creates a duplicate eSIM. API keys are scoped (catalogue, orders, esims, refunds), can be locked to your servers with an IP allow-list, and read-only test keys let your developers build without touching live orders.
White label for client-facing delivery
Partner eSIMs come with a neutral install page with no eSIM Signal branding, and the QR code can carry your colour and logo, previewed live before you save it. For a TMC this means the traveller sees your brand next to their itinerary. See how to sell travel data under your own brand for the full white label setup.
Team roles
Add consultants as users and keep finance and account leads as admins. Email two-factor sign-in protects every account, which matters when several agents share access to a funded balance.
Tip: put the client name or cost-centre code in
customer_reffrom day one. Retrofitting references onto months of orders is far harder than starting clean.
Choosing the right data package for business travellers
Business usage is heavier than a typical holiday: video calls, VPN traffic, cloud documents and large email attachments. A practical starting policy:
- Short trip, mostly meetings: 3–5 GB for a few days covers email, maps, messaging and the occasional call.
- Week-long trip with video calls: 10 GB or more, or an unlimited day pass where one is available for the destination.
- Roadshows across several countries: a regional plan instead of one eSIM per country. Partners also get partner-only regional plans such as Europe 33, Europe 50, Asia 14 and Asia 31.
With coverage in 210+ countries and regions from one account, you can serve the same client in Milan and Mumbai from the same balance, and choose between country, regional and global plans per itinerary.
Remember that the plans are data-only. Travellers keep their usual number for calls and texts on their home SIM, or use Teams, WhatsApp and similar apps over data.
Common mistakes and how to avoid them
- Ignoring device management. Many company phones are managed by an MDM policy, and some policies stop users adding a cellular plan. Ask each client's IT team to confirm eSIM is allowed on corporate devices before you launch.
- Sending the QR code only by email. A traveller reading email on the phone they need to install on cannot scan its own screen. Send the one-tap install link as well.
- Issuing on the morning of departure. Deliver the eSIM a few days before the trip so the traveller can install it on office or home Wi-Fi, and confirm that their phone supports eSIM first.
- Forgetting cancelled trips. Corporate travel changes constantly. Build a routine to refund eSIMs for cancelled trips while they are still uninstalled and inside the refund window; installed or used eSIMs cannot be refunded.
- No first-line support script. Prepare short answers for "data is not working" and "how do I switch lines back". Our customer support playbook for eSIM resellers has templates you can adapt.
Pricing the service to corporate clients
You see only your partner price and set the client price yourself. Some TMCs add a flat fee per eSIM, others fold data into a managed-travel fee, and some include it for strategic accounts. Partners with steady volume can agree a further discount on top of the standard partner price. To see what your own margin would look like on your clients' routes, get wholesale rates.
There is no setup fee, no monthly fee, no monthly minimum and no fixed-term contract. You can pilot with a single client and end the agreement at any time; eSIMs already delivered keep working until they expire. eSIM Signal supplies eSIMs only, so there is no physical SIM stock to hold or ship.
Frequently asked questions
What is a corporate travel eSIM?
It is a data-only eSIM issued to an employee for a business trip, usually booked and billed by the company's travel management company or travel desk. The traveller installs it before departure and uses it for data abroad while keeping their usual number on the home line.
Can a travel management company resell eSIMs under its own brand?
Yes. eSIM Signal partner eSIMs come with a neutral install page without eSIM Signal branding, and the QR code can use your colours and logo, while you set the retail price your clients pay.
Do corporate travel eSIMs include a phone number or calls?
No, the plans are data only. Travellers keep their normal number on their home SIM and can make calls through apps such as Teams or WhatsApp over the eSIM's data.
How do we recharge eSIM costs to each client or cost centre?
Add the client, trip or cost-centre reference as customer_ref on each API order, then use the itemised ledger exports in CSV or Excel to reconcile. Receipts are available for each transaction.
What happens if a business trip is cancelled?
If the eSIM was never installed, you can refund it to your partner balance within the refund window. Once an eSIM has been installed or used it cannot be refunded.
