Business line calculator
Paying for more lines or data than you use is common. Enter what you have, and we'll suggest a size and the cheapest checked plan that fits, with the saving against what you pay now.
Prices exclude VAT unless stated.Checked on each provider's own page, 5 November 2026.SimSift is independent. Most links in SimSift for Business are plain links we don't earn from.

Estimated saving = your bill minus the average monthly cost of the suggested plan over its term (including stated rises) for the lines in use, ex VAT. It's a guide, not a quote: networks may offer multi-line discounts we haven't included. We count only that the calculator ran and the saving shown, rounded to the nearest pound.
