Vodafone UK is "backing Britain's growing army of small businesses" with a new "simple value-for-money" price plan designed for needs of businesses with 20 staff or less.

The Small Business plan offers free calls, 24 hours a day, to an area code of the customer's choice as well as free calls to any other businesses on Vodafone business price plans.

Other free calls on the plan include calls between company mobiles and up to five company landlines. The plan, which starts from £22 per month, also includes an option to add email.

Small Business is supported by Vodafone UK's Small Business Promise, which includes freedom to switch price plans after six months, exclusive 24 month handset replacement option, network transfer promise and dedicated business support with "same advisor" routing and no voice-recognition systems.

Minimum contract lengths, call time limits and other small print-style conditions apply. More information on Small Business and Small Business Promise is available on the website.
