I wanted something I could use occasionally when I'd run out of data on my contract phone - took a 2 year deal with T Mobile (regret it now!) and this is great. I put it in my old phone and now I have unlimited data for spotify, Netflix etc. It's cheaper to just buy a new sim than top up! Bargain...I've just ordered my second. The first arrived within a day of ordering so I had no hesitation with reordering.
