Perhaps, but if it’s locked to O2 it may still make sense for them to sell the phone with no airtime requirements. In the US you can buy a Nokia Lumia 520 for $60 without contract (but locked to AT&T), or the Motorola Moto G for $90 no contract (but locked to Verizon). Both phones cost over double that when unsubsidized. Maybe it makes more sense to subsidize smart phones with the expectation of lucrative data fees, or maybe it makes more sense to subsidize feature phones whose only purpose is to consume airtime and cannot be used as cheap iPod touches.
