One.Tel - the fixed line discount telco - has teamed up with Vodafone to enter the mobile phone market.

Promising low prices, line rental for the service costs £4.99 a month - around 60 per cent cheaper than average line rental charges from other operators.

Unlike other services, there are no inclusive calls provided with this tariff. Calls cost from between 3p to 25p a minute.

One.Tel - part of Centrica - reckons punters can save up to £100 a year compared to other service providers.

One.Tel's new mobile phone service also allows for up to five phones on one account, at an extra cost of just £2.99 per additional line. ®
