3 offers 15GB for £15 on one month contract

Just as O2 UK takes the wind out of the iPhone 3G’s sails, by announcing plans to charge extra for tethering, Hutchison Whampoa-owned rival 3 UK looks keen to scrap with a low commitment mobile broadband offering.

After rocking the market with a 15GB for £15 offer, 3 has come in with another credit crunch busting offer for those who don’t want to get themselves tied into a lengthy contract.

For £15 per month, 3 UK customers can pick up 5GB of data, with just a one month commitment. Consumers can cancel by giving just 30 days notice.

The tariff is designed to tempt prepay users over to a contract without any serious commitment. A USB mobile broadband dongle is available from 3 for £19.99.

O2 has a mobile broadband Bolt On available for both iPhone and dongle users on a rolling one month contract, but you only get 3GB for £15, and the modem costs £60. O2’s other offer is 10GB for £30 per month.
