Order UK business lines

Add a UK business number in a few clicks, assign to the employee it belongs to and email them the eSIM QR code.

Usage and spend controls

See data use per line in real time, set spend alerts and move anyone to a bigger or smaller plan from next month.

One consolidated invoice

Every business eSIM on one monthly bill, with cost centres and CSV exports your finance team can reconcile.

Your company, your UK line

When someone leaves, reclaim their UK number and reassign it the same day. Customers keep calling the same line.

UK Business eSIM:
From Sole Traders to Enterprises

ZIM business eSIM lines work for any company trading in the UK, or selling into the UK from abroad. Every line is a company owned UK mobile number on rolling monthly terms.

Reasons UK Teams Move to a Business eSIM Line

01

Business eSIM, ready in minutes

No physical SIM card to post. Each business eSIM is issued digitally and activates instantly, so new starters are connected on day one. For BYOD it enables a separate business line on an employee's personal device.

02

No contract lock-in

Rolling monthly terms with no setup fees. Pay only for your mobile plan, switch plans any month, or cancel when you need to.

03

Great rates on the Vodafone network

Competitive pricing on one of the UK’s most trusted networks, with reliable coverage nationwide.

04

Number porting and retention

Port your existing numbers to ZIM and we handle the switch seamlessly. On BYOD, the company keeps the number when an employee leaves, so customer contacts stay with you.

05

One portal for every line

Set up eSIMs, assign lines by team or office, and manage it all from a single dashboard. One consolidated monthly invoice with itemised usage per employee.

06

A real UK number that passes 2FA

Unlike VoIP and virtual numbers, it runs on mobile network infrastructure, so it verifies with banks, supplier portals and WhatsApp Business without being rejected.

07

International Roaming for teams on the move

Affordable international roaming built in or as an add on, so your team stays connected when travelling for work.

08

More tax efficient than a phone allowance

A cash allowance counts as taxable pay. An eSIM on the company’s own contract is exempt under ITEPA 2003 s.319: no income tax, no NIC, no P11D, and the VAT is reclaimable.

A Secure UK Business Line

Every ZIM UK business number is a native mobile line, not a VoIP number or a forwarding service. Calls and texts run on the operator network end to end, so one time passcodes arrive, banks accept the number and nothing passes through a third party server.

UK Business Mobile Number vs
VoIP Number

A VoIP number is cheap to set up, but it runs over the internet rather than the mobile network. That's why banks, one time passcodes and messaging apps often reject it. A ZIM UK business number is a native Vodafone UK mobile line.

BYOD:
The Benefits of Business eSIM
vs Personal Line or Corporate Phone

A ZIM business eSIM on an employee's personal phone gives you the control of a corporate phone without buying handsets. The device stays off your books, while the number, the service and the billing stay with the company.

FAQ

Frequently Asked Questions

Everything you need to know about ZIM UK eSIM plans and UK business numbers.

How do I buy a UK business eSIM plan?

After registering an account on the ZIM Business portal, click on "Domestic Plans" and then "Order Plan". Select one of the plans shown or click on "See more plans" to see all the options. Choose the plan and click "Continue with selection". Type in the email address of the user(s) and make the payment, and the QR code will be sent to the recipient's email address so they can download and activate the service. The plan auto-renews each month and can be changed or cancelled in any given month.

How fast is activation?

A ZIM business eSIM is issued in seconds and usually live within minutes. Order in the ZIM Business Suite, email the eSIM QR code to the employee and they install it on their phone. No shop visit and no physical card.

View the eSIM compatible devices guide

Does the UK business plan include international calling (IDD) and roaming abroad?

Some UK business plans come with IDD and roaming included, whilst others do not, which keeps prices down for those that do not require it. Where IDD and roaming are not included, these services can be purchased as a bolt-on.

How do 2 active mobile lines run on 1 mobile phone?

A phone feature called Dual SIM Dual Standby (DSDS) lets two different phone numbers or SIM profiles (physical SIM cards, eSIMs, or a mix of both) operate on a single device. Both numbers are connected to their cellular networks at the same time, and incoming calls or text messages can be received on either number. When making an outbound call, select which line to call from in the prompt.

Can a number be ported in or out?

Yes. You can bring an existing UK mobile number to ZIM, or move a ZIM number to another provider. To port in, text PAC to 65075 from the number you want to move to get a free Porting Authorisation Code, then send it to [email protected] with the line it should go on. To port out, request your PAC from ZIM and give it to your new provider. Under UK rules, the switch usually completes within one working day.

Can overseas companies get a UK number?

Yes, overseas companies can get UK business numbers with ZIM. Companies outside the UK use ZIM for a local UK presence, customer calls, verification and banking, without signing a UK carrier contract.
