Is there any evidence that Three has a major problem with users tethering and replacing their home broadband connection?
Of course Three is right to be mindful of future problems, but I am not aware that all of the issues today are down to people who have hooked up their mobiles via USB (or as a portable hotspot) to their computer, or bought a router with USB port to share around the home.
No doubt some people are doing it, but how many? Probably very few. I bet very few even know how to do the latter (which would be the only proper way to do it if you wanted to connect your computer, Smart TVs, set top boxes, consoles etc).
I only found this thread just now. I thought it had already been discussed elsewhere and explained, but clearly that wasn't enough and our resident anti-Three member decided to create a new thread to spread such misinformation.
Yes, I expect tethering to end on NEW SIM-only plans, but for nothing to change for existing users. I can't see why Three will feel the need.
If Three really had massive congestion problems, it would be axing AYCE data completely, not just stopping tethering.
