**T&cs and methodology: Average saving is based on customers that purchased a new contract between 1st Jan 2017 and 31st May 2017. For 56% of customers we were able to directly compare the total cost of ownership of the deal purchased from Carphone Warehouse vs. the network's (Vodafone or O2 or EE) published website price. Total cost of ownership is calculated by: monthly cost x 24 + upfront cost - any cashback.  Matched tariffs are where minutes, texts and data are the same. Total matchable transactions in this period were 410,286. The total match rate between 1st Jan 2017 and 31st May 2017 was 56% (includes iD where there is no match). This breaks down to 73% for O2, 85% for Vodafone and 41% for EE.  Excludes any deals with gifts or other promotions. Excludes any tariffs that we do not range or sell.
