I thought this would be a real hassle but it’s turned out to be easy.
If there is no wifi and you want to use your laptop to get email or whatever, you just go to settings on your iPhone and slide the Personal Hotspot switch to on. It is now broadcasting its own little wifi hotspot.
The first time you set it up you have to put the code (the iPhone shows it) into your laptop, but every time after that you just look at the list of wifi available on the laptop and select Chris’s iPhone, and there you are, connected to the web.
I’ve used it quite a few times this month and am still well within my gig of data, so for the things I use it for it seems to be great.
No need for the cost and hassle of a dongle ever again!
Give it a go if you have been nervous about trying it.
