Orange have started using t-mobile to try and get better signal but you will find this will be worst thing they ever did. More peoples will have dropped calls so very frustrating if your on a very important call an it cuts off half way through. Vodafone customer service is second to none. Brilliant company, brilliant signal and fantastic prices. Vodafone are leaders not followers in the Market know one compares to them. They were the first to bring 3G coverage to the uk! Brilliant roaming rates also.
