It makes zero difference, do you really think it uses more data to tether? HD screen or HD screen doing the same thing.
As I said this move will reduce my data usage by zero. It just inconvencies me. As I'll have to watch stiff in the phone compared to tablet.
Data limits should be allowed on anything as it really does make zero difference what device you use it on.
Will have to look into screen projector apps.
USB-HDMI cables are readily available, that's probably what you need. Less reliable/easy to use compared to just using a PC but there you go.
Looks like £5/GB for extra internet from 3 - I can't imagine their cost of providing internet is near even a tenth of that cost, or they would be bankrupt based on the number of people apparently using hundreds of gigabytes of data for £15/month at the moment! Surely charging such excessive amounts is counterproductive.
Ignoring tethering for a moment, a serious issue with this is the pricing structure.
I currently pay £18/month for a 1 month rolling One Plan with unlimited data, 5000 3-3 minutes, 2000 other minutes and 5000 texts/month.
My options with the new contract are to pay £23 for unlimited data, 600 minutes and unlimited texts, or £28 for unlimited data, unlimited minutes and unlimited texts.
Like I suspect the vast majority of users, I don't get anywhere near my current minute or text allowance. So I'm left with the option of paying an extra £10/month for at best the same service.
And that's before the removal of unlimited tethering, obviously.
