*Average saving is a comparison based on selected pay monthly handsets where the prices are published on O2 and CPW websites and we were are able to directly compare the total cost of ownership of the equivalent tariff plan (with the same or greater data inclusions) on Vodafone, EE and Virgin available from Carphone Warehouse vs. O2’s direct price. Total cost of ownership is calculated by: monthly cost x 24 + upfront cost - any cashback. Matching criteria excludes all plans where an upfront cost was greater than £200. Comparison undertaken on the 13/8/2020.

Price Promise - If you find an upgrade, pay monthly SIM only or pay monthly deal for less at  EE or Vodafone, we'll match it and pay the equivalent of your first month's standard line rental via cheque. Applies to published prices only where the handset is in stock and available for immediate purchase or dispatch. Proof of competitor price(s) required. Full T&Cs click here.
