GBP amounts match the prices displayed in our billing system, checked on 17 September 2026. Any applicable VAT and the final payable total are confirmed at checkout. International calls, premium-rate services and out-of-allowance usage are not automatically included.
Billing period and contract term are different
Business plans on this page offer advance payment for 3, 6, 12 or 24 months. A billing period does not by itself change the minimum service contract. GSM 1–5 have a published one-month minimum contract. GSM 6 includes unlimited 4G data and has a published 12-month minimum contract.
Confirm coverage, activation, number transfer, cancellation terms and any fair-use conditions before ordering. Do not cancel your existing service before your number transfer is agreed.
