O2 has announced it has reduced the minimum spend for a "Pay & Go" tariff that is says is "designed to give Pay & Go customers unlimited peace of mind when surfing and texting".

The "Text & Web" tariff, usually for those who top-up £30 a month, is now available to those who top-up £15 a month and offers unlimited mobile web access and unlimited text messages.

Available to customers who join before 31 October, those who top-up up to £14 a month still gets unlimited free UK texts.

O2 promises its unlimited allowances "carry no hidden charges", but does apply an "excessive use" policy, details of which can be found in the small print.
