if true, i have till March 2015,
although to be fair id he happy with unlimited everything and 4Gb tethering for £15 per month, sim only and rolling contract
This is the line i was given last week when i renewed, all unlimited tethering would be stopped when minimum term reached, spoke to numerous departments and even instore, all said the same thing, was recommended to submit official complaint and encourage as many to do the same.
the way they explained it to me was that they offered the unlimited tethering expecting other networks to follow suite, unfortunately this has not been the case, apparently its causing a lot of network congestion and costing them a lot of money, therefore they have decided to stop offering it, when i questioned this they said something along the lines of they have the right to change conditions of the contract* and what not, and as a measure of good faith they were allowing people to continue to use it till the minimum period is up.
*dont know if this was true or not, not checked fine print of my contract.
But either way my time was up anyway, dont actually use much in the way of tethering myself, so no great loss, but it was nice to know it was there if required.
Also after looking round i havnt found any other networks that offer as good a deal even without unlimited tethering.
A bit miffed, but i'm still happy to stay with Three.
