Not sure which plan you need? Most people use less mobile data than they think, because their phone is on Wi-Fi at work and at home. Tell us how your team works and we’ll recommend the right mix.

Every plan includes

The things businesses actually need, as standard

  • No mid-contract price rises

    On a 12- or 24-month contract, the price you sign up at is the price you pay for the whole term.

  • Keep your number

    Bring your existing mobile numbers with you. We'll handle the move from your current provider.

  • UK-based support

    Our team is here 8am to 6pm, Monday to Friday.

  • Move up at any time

    If you need more data, move from Essential to Unlimited whenever you like, without starting a new contract.

  • One bill for everything

    Every SIM on one monthly invoice, alongside your broadband and phones if you have them with us.

  • eSIM or physical SIM

    We set you up with an eSIM by default, so there's no waiting for a SIM card in the post. Prefer a physical SIM? Just tell us when you order.

Good to know

Unlimited calls and texts are to standard UK landline and mobile numbers. Unlimited data is for normal business use and a fair use policy applies. Using your phone abroad, and calls to international and premium rate numbers, are charged separately. Mobile Broadband is a data-only SIM, so it can’t make calls or send texts.

Switching to us

  1. Send us an enquiry.

    Tell us how many SIMs you need and a little about how your team uses their phones.

  2. We confirm and advise.

    We’ll recommend a plan for each person and check coverage where you work: no pressure, no jargon.

  3. We set up your SIMs.

    By default we send each person an eSIM to install on their phone in a few minutes. If you’d rather have physical SIM cards, we’ll post them to you.

  4. Your numbers move across.

    Ask your current provider for a PAC code for each number you want to keep and pass it to us. Numbers usually move on the next working day.

Better together: mobiles, broadband and phones

Many of our customers take their business broadband and hosted phone system from us as well. You get one bill and one team who know your whole setup, so there is no passing you between providers when something goes wrong.

Frequently asked questions

Can I keep my mobile number?

Yes. Ask your current provider for a PAC code and pass it to us. Your number usually moves across on the next working day, and your old contract ends automatically.

Which network do you use?

Our Business Mobile plans run on the Vodafone network. Tell us the postcodes where you work and we’ll check coverage before you order.

Do you offer eSIMs?

Yes. We supply an eSIM by default: it installs on your phone in a few minutes, with no SIM card to wait for or lose. Most recent phones support eSIM. If yours doesn’t, or you’d simply prefer a card, choose a physical SIM when you order.

How long is the contract, and what happens at the end?

Choose 24 months, 12 months or 1 month for each SIM. After your minimum term, your service carries on month by month and you can leave with one month’s notice.

Will my price go up?

Not during a 12- or 24-month contract. The monthly price you sign up at is fixed for the whole minimum term. On a 1-month contract we can change the price, and we’ll always give you notice first.

What happens if I use all my data on Essential 20GB?

You can add more data for the rest of the month, or move to Unlimited at any time without starting a new contract. If it happens regularly, we’ll suggest the plan that works out cheaper for you.

Can I use my phone abroad?

Yes. Roaming is charged at a daily rate for each day you use your phone abroad. We’ll confirm the rates for the countries you visit when you order.

Can I use an Unlimited SIM in a router or tablet?

No. Unlimited and Essential are for phones. For a 4G or 5G router, tablet or laptop, choose Mobile Broadband, which is a data-only SIM.

Do you supply phones?

Yes. We sell handsets outright, so the phone is yours from day one and isn’t tied to your airtime contract. You can also use the phones you already have.

Is there a minimum number of SIMs?

No. Order one SIM or one for everyone in the business, and add more whenever you need them.

Send us an enquiry

Tell us how many SIMs you need and which numbers you want to keep, and we'll recommend the right plans. We reply to every enquiry within one business day.
