I've got a Sony experia l on the starter tariff (£16 a month). I can upgrade in two weeks and I like the look of the HTC one m8s. Once my contract is finished does anybody know how much the tariff on it's own will be as I assume I will have paid for the phone over the 2 years.
Can't answer that, because the old tariffs weren't split into phone and service. While it was quite obviously a credit agreement for a handset, legally it was "commit to paying this much per month for two years for this level of service, and you get a free phone".
What sort of service (minutes/texts/data) did you get with the £16 Sony tariff?
