Business eSIM UK 2026: Setup, Benefits & Plans for Companies

The way UK businesses manage mobile connectivity is changing fast. eSIM technology — already standard on the latest smartphones, tablets and laptops — is making physical SIM cards obsolete for forward-thinking companies. If you are responsible for equipping a team with mobile devices, understanding business eSIM could save you time, money and a lot of logistical headaches.

In this guide, Connection Technologies explains everything you need to know about business eSIM in the UK for 2026: how it works, which networks support it, which devices are compatible, and how to get set up quickly.

What Is an eSIM and How Does It Work?

An eSIM (embedded SIM) is a small chip built directly into a device during manufacturing. Unlike a traditional SIM card that you physically insert and swap, an eSIM is reprogrammed digitally. Your network operator sends a profile — essentially the same data that lives on a plastic SIM — over the air, and the device activates within minutes.

The technology is governed by the GSMA standard, which means eSIM profiles work across all major networks and device manufacturers. When you activate a business eSIM, you scan a QR code or receive an activation link, the profile downloads, and the device connects to the network. No waiting for a SIM card in the post, no fiddly trays, and no risk of losing a tiny piece of plastic.

For businesses, the real power of eSIM is remote provisioning. IT teams can activate, swap or deactivate lines without ever touching the physical device — a game-changer for companies managing dozens or hundreds of handsets.

Why Businesses Are Switching to eSIM

Adoption of business eSIM in the UK has accelerated sharply since 2024. Here is why so many companies are making the switch:

No Physical SIM Required

Ordering, shipping and inserting SIM cards for every new starter or device refresh is time-consuming. With eSIM, provisioning happens digitally — often in under five minutes.

Instant Activation

New employees can be online the same day they receive their device. There is no waiting 24-48 hours for a SIM to arrive. This is especially valuable for businesses with high staff turnover or seasonal workers.

Dual SIM Capability

Most modern smartphones support one physical SIM and one eSIM simultaneously (or two eSIMs on the latest iPhones). This lets employees carry a single device for both business and personal use, reducing hardware costs and improving adoption.

Remote Provisioning for Teams

Through Mobile Device Management (MDM) platforms, IT administrators can push eSIM profiles to devices remotely. This is invaluable for distributed teams, field workers and international offices.

Reduced Environmental Impact

Eliminating millions of plastic SIM cards, packaging and postal deliveries makes eSIM a genuinely greener option — something that matters for businesses tracking their ESG commitments.

Better Security

An eSIM cannot be physically removed from a stolen device, making it harder for thieves to disable tracking or wipe the connection. Combined with remote lock and wipe capabilities, eSIM strengthens your mobile security posture.

Which UK Networks Support Business eSIM?

All four major UK networks now support eSIM, though the depth of their business eSIM offerings varies:

EE

EE was the first UK network to offer eSIM and has the most mature business eSIM proposition. Business accounts can order eSIM profiles through their account manager or the EE business portal. EE also supports eSIM on tablets and selected laptops.

Vodafone

Vodafone offers eSIM across its business plans, including shared data and unlimited packages. Vodafone Business has integrated eSIM provisioning into its V-Hub management platform, making fleet activation straightforward.

O2

O2 supports business eSIM on all current tariffs. O2 Business customers can manage eSIM activations through My O2 Business, and O2 has been expanding its eSIM support for IoT and data-only devices.

Three

Three launched eSIM support for business customers in 2024 and now offers it across all business plans. Three is particularly competitive on data-heavy plans, making it a strong option for businesses that need large data allowances on eSIM.

Which Devices Support eSIM?

eSIM support has expanded rapidly. Here are the most common business devices that support eSIM in 2026:

Apple iPhone

Every iPhone from the iPhone XS (2018) onwards supports eSIM. The iPhone 14 and later models sold in the US are eSIM-only (no physical SIM tray), and UK models support dual eSIM. The iPhone 16 range supports up to eight eSIM profiles stored simultaneously.

Samsung Galaxy

Samsung has supported eSIM since the Galaxy S20 range. The Galaxy S24 and S25 series, Galaxy Z Flip and Z Fold ranges all support eSIM. Samsung Knox — Samsung enterprise security platform — integrates eSIM provisioning for business fleets.

Google Pixel

Google Pixel phones have supported eSIM since the Pixel 2. The Pixel 9 range supports dual eSIM, making it a popular choice for businesses using Android Enterprise management.

iPads and Tablets

The iPad Pro, iPad Air and standard iPad (from 2018 onwards) all support eSIM, making them ideal for field workers, sales teams and point-of-sale applications without needing a Wi-Fi connection.

Laptops

Selected business laptops from Lenovo, HP and Dell include eSIM support, allowing always-on connectivity without tethering to a phone. This is particularly useful for remote workers and executives who need reliable connectivity on the move.

How to Set Up a Business eSIM

Setting up an eSIM is straightforward. Here is a step-by-step guide for the two most common platforms:

Setting Up eSIM on iPhone

1. Order your eSIM plan — Your provider (or Connection Technologies on your behalf) will send a QR code or activation link via email.
2. Open Settings on the iPhone and tap Mobile Data (or Cellular).
3. Tap Add eSIM — then choose Use QR Code.
4. Scan the QR code provided by your network operator.
5. Label the plan — choose a label like “Work” to distinguish it from a personal line.
6. Set as default line — choose the eSIM as your default for data, calls or both.
7. Done — the eSIM activates within minutes and you will see signal bars for the new line.

Setting Up eSIM on Android (Samsung / Pixel)

1. Order your eSIM plan — receive your QR code or activation details.
2. Open Settings and go to Connections > SIM Manager (Samsung) or Network & Internet > SIMs (Pixel).
3. Tap Add eSIM and select Scan QR code.
4. Scan the QR code — the device downloads the eSIM profile.
5. Enable the eSIM and set it as your preferred line for data and calls.
6. Restart if prompted — some devices require a restart to complete activation.

For bulk deployments, your IT team can use MDM solutions like Microsoft Intune, VMware Workspace ONE or Jamf to push eSIM profiles to devices automatically — no QR scanning required. For help setting this up, visit our SIM and eSIM help centre.

Business eSIM for Teams and Fleet Management

The real business case for eSIM goes beyond individual device setup. For companies managing fleets of 10, 50 or 500+ devices, eSIM transforms how you provision and manage mobile connectivity.

MDM Integration

Modern MDM platforms support eSIM provisioning as part of zero-touch enrolment. When a new device is unboxed and connected to Wi-Fi, the MDM automatically pushes the eSIM profile, security policies and business apps. The employee is ready to go without any IT intervention.

Remote Provisioning

Need to activate a line for a new starter working from home in Edinburgh while your IT team is in London? With eSIM, you send a profile remotely. No SIM card in the post, no delays.

Network Switching Without Downtime

If you decide to move your fleet from one network to another — perhaps to get better coverage in a new office location — eSIM lets you download new profiles without collecting and redistributing physical SIM cards.

Cost Control

eSIM management platforms give administrators a clear view of which lines are active, which are unused, and where data consumption is highest. This visibility helps eliminate waste and control costs.

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

Can I use eSIM and a physical SIM at the same time?

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.

Is eSIM available on all UK business mobile plans?

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.

What happens to my eSIM if I change device?

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.

Can I store multiple eSIM profiles on one device?

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.

Is eSIM more expensive than a physical SIM?

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.
