What's the Best Travel eSIM for Your Employees?

A Business Travel eSIM Checklist

Quick answer: The best travel eSIM for employees is a business travel eSIM from an operator that runs its own core network, routes traffic over a private APN, and lets IT activate, suspend and monitor every eSIM centrally, with an audit trail and one consolidated invoice. Consumer travel eSIM apps are built for cheap holiday data, not for handling company or client information.

Your employees are probably already using travel eSIMs. The real question is whether the one on their phone is fit for company data.

Buying a travel eSIM has never been easier: install an app, pay a few euros, and you are online the moment you land. For a holiday, that is all anyone needs. For a consultant opening client files in an airport lounge, or an executive joining a board call from a hotel abroad, it is a very different story.

This guide explains what separates a consumer travel eSIM from a business travel eSIM, and gives you a practical checklist for choosing the right option for your teams.

Why do consumer travel eSIMs fall short for business?

Business travelers usually fall back on one of three workarounds. They switch off data to avoid roaming bills and lose productivity. They join unsecured hotel or airport Wi-Fi. Or they download a consumer travel eSIM. Each one creates a risk for the business.

Consumer eSIM apps compete on one thing: the lowest price per gigabyte. Security, compliance and IT oversight simply aren't part of the product.

Independent research presented at the USENIX Security Symposium highlighted several recurring issues across consumer eSIM platforms:

•       Traffic is often routed through servers in other countries, wherever the user happens to be.

•       Becoming a reseller can take little more than an email address and a credit card, yet resellers can see unique identifiers (IMSI, ICCID and IMEI) and location data accurate to around 800 metres.

•       Services run on shared infrastructure spread across multiple, often undisclosed, jurisdictions.

•       Some eSIMs open hidden connections to remote servers or receive unsolicited SMS messages, without the user knowing.

In practice, that means corporate email, VPN credentials and client data may be crossing networks your IT team has never reviewed, in countries your policies never approved.

For regulated or security-sensitive sectors such as pharma, financial services, defense and healthcare, this is a live exposure, not a hypothetical one.

Consumer vs business travel eSIM: what's the difference?

The difference comes down to who controls the network, the data and the SIMs themselves.

The business travel eSIM checklist: 7 questions to ask

Run through these questions before you choose, or renew, a travel connectivity provider. If the honest answer to any of them is "we don't know", your teams are likely relying on consumer-grade connectivity for business-critical work.

1.     Does the provider run its own core network? Resold capacity adds routing hops you can't see or audit.

2.     Can IT activate, suspend and monitor eSIMs remotely? If a device is lost or compromised abroad, you need to act in minutes, not days.

3.     Is traffic carried over a private APN? Public routing pushes your data across shared infrastructure.

4.     Can you see usage in real time, by employee, country and device? This underpins both cost control and anomaly detection.

5.     Is the solution GSMA-compliant? It confirms the provider follows international eSIM security standards.

6.     Is the provider independently audited, with security SLAs in the contract? Ask for audit reports and certifications before you sign.

7.     Do you get one consolidated invoice? Per-employee billing quietly turns connectivity into shadow IT spend.

What does the best business travel eSIM look like?

The right business travel eSIM ticks every box above. Telecom26's Business Travel eSIM was designed for corporate use from day one, rather than adapted from a consumer app.

•       A global operator, not a reseller: Telecom26 owns its network core, so data stays off third-party aggregators and unverified routes.

•       Coverage in 200+ countries and territories: devices connect automatically to the strongest network, backed by 650+ operator partners and 1,100+ network connections.

•       One management portal: IT can activate, suspend and monitor every eSIM from a single dashboard.

•       Secure, transparent routing: all traffic runs over Telecom26's own backbone, with optional VPNs, Direct Connect and private APNs to keep it inside your security perimeter.

•       One contract, one invoice: finance gets predictable costs, IT keeps control.

•       Shared global data pools: pooled group bundles mean no overpaying for unused data and predictable monthly costs.

•       Simple activation: employees scan a QR code and keep their primary number for calls and SMS.

•       Dedicated B2B support: help comes from engineers who understand enterprise IT, not a tourist helpdesk.

•       Swiss-headquartered and GSMA-compliant: built for organisations where compliance is non-negotiable.

Use case: how a financial services firm keeps its travelers connected

OCORIAN, a financial services firm, moved its business travellers onto Telecom26 eSIMs. Employees download the eSIM once, and it activates automatically when they land in another country, so travelers know they will be connected from the moment they arrive.

The verdict: give employees a better option, not a ban

Consumer eSIMs aren't a corporate travel strategy. They're a personal convenience that employees reach for because nobody has offered them a business alternative.

Banning them rarely works. The better move is to provide connectivity that is secure, centrally managed and built for how your teams actually travel.

Whether you're reviewing your travel budget or preparing a vendor security assessment, use the checklist above as your starting point. Then see how Telecom26's Business Travel SIM and eSIM solutions measure up.

Frequently asked questions

What is the best travel eSIM for employees?

The best choice is a business travel eSIM from an operator that owns its core network, routes traffic over a private APN, and gives IT central control, usage visibility and an audit trail.

Are consumer eSIMs safe for business travel?

Most are built for cheap, convenient connectivity, not enterprise security, compliance or IT management, so they leave gaps when employees handle company or client data.

What is a business travel eSIM?

It's a centrally managed mobile connectivity service for travelling staff, offering secure routing, compliance controls, auditability and full IT visibility.
