Got a T-mobile SIM for my partner via Travelgear for September 2011 - it worked without any dramas and the option with the free international calls came in very handy. I wouldn't be confident recommending them based on just this one exposure some time ago, but as with Kerrodt my experience was a positive one. Before seeing some of the remarks here I had simply planned to do this again for my partner for September 2013, now I will reconsider other options also.
