Just joined 'Oviva Mobile' NO CONTRACT. If you are a low usage user really seems a great deal!! Vodaphone is the network provider from what I can see. You may have to put up with the odd advert but seems a very good offer. 150 min to any network, 500 megabytes, 300 texts all FREE per month! Oviva to Oviva FREE. Initial cost is £5 for sim and £15 credit which can be topped up if you go over your FREE monthly limit! Transfer existing mobile number . . . all very easy and customer service was excellent! Might save you funsters a bob or two!!!
