I have a 3G card
It’s expensive
Coverage is patchy
But if you use it for work
You can very quickly, pay its way
I have friend who uses “the starbucks system” it seems cheap, fast and reliable
But if its midnight, you urgently need an Internet connect, and the nearest starbucks is a 100 miles away …..
Another friend connects her laptop via her mobile, seems cheap, reliable but very slow
