Folk with mobiles on Vodafone, EE and Three are being stung by an average £22 per month for staying on their contracts after their handsets have been paid off, according to Citizens Advice.

Customers who choose to stay on the same plan after the two-year fixed deal ends are not getting their bills reduced, meaning they are paying extra for a phone they already own.

CableLabs, Cisco working on LTE-over-DOCSIS
Thursday, 19 October 2017 13:57

+COMMENT Cisco and CableLabs have put their heads together in the hope they can convince mobile network operators that with a bit of unicorn-dust, DOCSIS networks can support the LTE small-cell rollout.
