Subscription fees will start at £30 per month under a two-year contract, while phones will cost between £59 for an 8GB iPhone 3G and £239 for a 32GB iPhone 3GS, said Vodafone.
Each contract includes unlimited text messaging. All plans will have a 1GB monthly data limit, which is higher than the 750MB cap imposed on Orange subscribers, but restrictive by comparison to O2's unlimited cellular data.
Both Vodafone and O2 offer unlimited data via their associated Wi-Fi hotspots.
To overcome its competitors - Orange UK and T-Mobile UK-Vodafone said it aims to offer superior network service over competitors, especially with the iPhone.
Meanwhile, AT&T, the only U.S. wireless provider supporting the iPhone, has been slow to upgrade its networks, and instead blames iPhone owners for its lackluster 3G coverage.
