O2 UK countered Vodafone's recent SIM-only plan with one of its own just for iPhone users. The monthly "simplicity for iPhone" plans at £15 for a 1-year contract or £20 contract-free give those who already have an iPhone a much less expensive alternative to using the device without sacrificing features. At the base level, these provide 300 minutes, unlimited data, UK texting and Wi-Fi with tethering an option at either £2 maximum per day or a flat £10 per month for 3GB of use.
