Here we have a range of sim only contract deals for people who need a lot of minutes a text messages. All deals are of £30 or more a month and vary in contract length all the way from a 30 day rolling sim only contracts to 12 and 18 month contracts. A sim only contract is whereby you decide that you dont need a new phone because your current phone does its job perfectly. With a sim only contract you dont get a mobile phone and instead you get just the sim card. With no 'free' expensive phone in the deal, these savings are then passed on to you - the customer - meaning you can lower your monthly phone bills as well as getting a more attractive deal.
