Secure, Managed eSIM Data for Business | idealesim
This page is for IT and security teams who need to decide how employees get online when they travel, without opening up a new attack surface. A data-only travel eSIM from idealesim is bought online in 175+ countries, installed by scanning a QR code, and runs alongside the employee's normal SIM - no physical card, no carrier roaming contract, and no dependency on whatever network happens to be available at the destination.
Why airport Wi-Fi and borrowed SIMs are the weaker option
Public Wi-Fi at airports, hotels and cafes puts a device on a network you don't control and can't audit. Traffic can be intercepted or redirected, captive portals can prompt for credentials, and there's no way to confirm who else is on the same access point. A local SIM bought at arrival isn't much better from a management standpoint: it's a new, unverified network path issued by a carrier you have no relationship with, on a card that's easy to lose track of and impossible to centrally provision.
A data-only eSIM avoids both problems. The employee's device connects through a plan your business bought and controls, not an open network or a walk-in purchase. Because it's data-only, their existing work number stays active for calls and SMS - nothing about their normal contact details changes, and nothing has to be forwarded or diverted.
Compatible with the tools your security stack already requires
The eSIM is just a mobile data connection, so it works the same way any other connection does with corporate VPN clients, encrypted email, and secure cloud storage or collaboration tools - there's nothing to configure differently on the security side. Video calls on Teams or Zoom run fine over it too. If your policy requires VPN-on-connect or specific DNS settings for travelling staff, those policies apply exactly as they would on any other data connection, because the eSIM doesn't sit in front of or interfere with device-level controls.
Because plans are bought as a known quantity up front, there are no surprise roaming charges landing on a personal or corporate card while someone is abroad, and receipts are expense-ready - useful when finance and security both want a clean paper trail for a trip.
How it works in practice for a travelling team
A manager or IT admin places a single order covering everyone travelling - say, a group heading to Germany, a colleague going on to Spain, and someone else heading to the United States. Each person in the order gets their own unique QR code, so there's no shared credential or shared login to manage. Before departure, each employee scans their code and the eSIM installs alongside their existing SIM - no need to swap a physical card in and out, and no need to hand devices back to IT for reconfiguration. For staff covering several countries on one trip, a regional plan such as Europe avoids buying and tracking a separate eSIM per border crossed.
For ongoing management, a team owner can handle every employee's eSIM from one place using Team Booking: seeing who has an active plan, adding new trips, and keeping the whole team's connectivity in one account rather than scattered across personal purchases and expense claims. If your organisation needs volume pricing or a single central invoice across many travellers, contact the team directly to arrange it.
Where this fits alongside other approaches
This page focuses specifically on the security case for a managed, data-only eSIM. If you're comparing how eSIM procurement fits into a wider policy for company travel, or how it supports staff who work remotely from different countries rather than travelling for short trips, those are covered on the sibling pages for corporate eSIM programmes and eSIM for remote teams.

Set up Team Booking to issue and manage eSIMs for your travelling staff from one account, or head back to the business travel eSIM hub to compare it with other options for your team.
