Business eSIM Security Considerations
Security is a top concern for any business deploying mobile devices. eSIM offers several security advantages over physical SIM cards:
- Tamper-resistant — Because the eSIM is soldered into the device, it cannot be removed by a thief to prevent tracking or disable the line.
- Remote wipe — If a device is lost or stolen, IT can remotely delete the eSIM profile, cutting off network access immediately.
- Profile encryption — eSIM profiles are encrypted during download and storage, meeting GSMA security standards.
- No SIM-swap fraud risk — Physical SIM swapping is a common attack vector. eSIM eliminates this by tying the profile to the device hardware.
- MDM enforcement — eSIM profiles can be locked to managed devices, preventing employees from transferring business lines to personal phones.
That said, businesses should ensure their MDM policies cover eSIM management, including rules for who can add or remove profiles and how decommissioned devices are handled.
Frequently Asked Questions About Business eSIM
Yes. Most modern smartphones support dual SIM — one physical and one eSIM (or two eSIMs on newer iPhones). This is ideal for employees who want to keep personal and business lines on one device.
All four major UK networks (EE, Vodafone, O2 and Three) support eSIM on their business plans. Some MVNOs also offer eSIM, though availability varies. Connection Technologies can advise which plans offer eSIM as standard.
You will need to transfer or re-download your eSIM profile to the new device. Most networks allow you to do this through their app or by requesting a new QR code. Your number and plan remain the same.
Yes. Modern iPhones can store up to eight eSIM profiles, though only two can be active simultaneously. Android devices typically support fewer stored profiles but are expanding capacity with each generation.
No. eSIM plans are priced identically to physical SIM plans on all major UK networks. There is no premium for choosing eSIM — and you save on postage and handling costs for bulk orders.

Business eSIM controls to verify
- Confirm eSIM availability for the exact operator, tariff and device; consumer and business support can differ.
- Document who can issue, transfer and revoke profiles, including leaver and lost-device procedures.
- Dual-SIM can support resilience or travel, but needs policy for data routing, personal lines and support ownership.
- For fleets, test bulk provisioning and MDM restrictions before replacing physical SIM workflows.
