Hi anyone on three with an iPhone 5 - does your personal hotspot work? In order for it to work you'd need to be on the one plan which includes tethering. On my phone sometimes it turns on & other times it says contact three to enable this feature etc I've had a replacement phone, tired reset network settings, restore, etc They three say it is an apple software bug. But if so why hasn't it been fixed! The only thing left is to try a new SIM card but they said I'd have to have a new number which I believe is wrong.. There must be a way to just replace a faulty SIM card. Cheers Ed Ps one last thing when using personal hotspot surely you should still be able to use the Internet on the phone itself in case of important emails etc on my phone enabling personal hotspot seems to just literally divert the Internet.
