UK mobile broadband provider 3 has increased the usage allowance available on its one month contracts.

Subscribers to the internet service provider's £15 per month deal can now use up to 5GB for this price, up from 3GB.

Users have two choices, accessing web services via a SIM card or through one of the broadband provider's dongles.

A 3 dongle can be added to the broadband deal for a one-off fee of £9.99.

Consumers should be aware that a charge of 10p per Mb is levied if the dongle usage allowance is exceeded during the month.

Last week, 3 added Velocent's OneVu 3G Mobile Broadband network monitoring system to its platform, in a move which could improve the reliability of consumer web services.

Phil Sheppard, Director of Technical Solutions at 3, said the service would help the firm identify operational faults in its network.
