By SimDeals·Updated 29 October 2026·5 min read

Buying mobile for a business comes down to more than the headline price. Pricing conventions, pooling and the rules around adding or removing lines are what actually determine the cost.

Key takeaways

  • Business prices are quoted ex VAT as well as inc VAT.
  • Data can be pooled by aggregation or by a single shared bundle.
  • Each connection carries its own 24 month term.
  • Roaming rates differ by network and matter for travelling teams.

Buying mobile for a business comes down to more than the headline price. The tariffs look similar, but pricing conventions, pooling and the rules around adding or removing lines are what actually determine the cost.

Key takeaways

  • Business prices are quoted ex VAT as well as inc VAT.
  • Data can be pooled by aggregation or by a single shared bundle.
  • Each connection carries its own 24 month term.
  • Roaming rates differ by network and matter for travelling teams.

Ex VAT pricing

Business and mobile broadband cards on this site show the ex VAT figure alongside the inc VAT price, because that is how most businesses budget and how VAT-registered companies experience the cost.

Pooling data across the team

You can either aggregate — every connection contributes its allowance to one account pool — or use a sharer model where lines have a low monthly charges and all data comes from a single shared bundle from 25GB to 5TB. The two models can't be combined on the same account.

Terms, adds and removals

Each connection carries its own minimum term. Moving a connection onto a new tariff restarts a fresh 24 month period for that subscription, and leaving early triggers the early termination fee on the remaining monthly charges.

Promotional tariffs are for new customers, so internal ports and renewals may not qualify.

Travelling teams

If staff travel, price roaming into the decision: O2 includes EU roaming with worldwide at £4.00 a day, Vodafone is £1.60 EU and £4.26 worldwide, and EE is £1.50 EU with a £5.00 a day business roaming rate and £9.00 a day world roaming.

Frequently asked questions

Are business prices shown ex VAT?

Both. Business and mobile broadband cards show the inc VAT headline price and the ex VAT figure underneath.

Can we add lines later?

Yes. Each new connection takes its own minimum term, and on a sharer account the shared bundle can be increased to cover extra demand.

What happens if an employee leaves mid-term?

Ceasing the connection before the end of its minimum term triggers the early termination fee for the remaining monthly charges, including any notice period.
