I have a mini sim on offer to loan to someone in Perth.
I bought it to use in my ipad when I was in Bali in September.
It was a normal size card trimmed down to mini size by the vendor.
I think it should work fine in an iphone as well.
If anyone would like to borrow it if they are travelling and returning in the next 3 weeks just email me.
I will forward it with the paperwork it came with so you will have access to the number and provider before you travel.
All I ask is that it is returned with a little credit on it upon your return.
