Concur.... good product.

I spent a week in October in a fairly isolated area of QLD... but had access the whole time there without ANY hiccups using one of those... I had checked.. and Telstras coverage map was the only one that even suggested that area would be OK... the others all insist on a street address when checking coverage zones... Bit hard when there is no streets!!!

There are "Plans" available too.. but for occasional use (all I need and all a visitor is likely to) the Pre-paid option seems best..

One small note... credit expires fairly quickly.. so don't buy tooo much initially!
