I posted on Tuesday about this sim card and thought I would give you an update.
I have been in Bali for 5 days and I still can't make overseas calls using the 01000. I've kept the same Bali number and have all the correct numbers in my mobile phone.
Over the last three years I have never had a problem, but now I'm told there is a problem with the service. The 01000 then 61 and the number does not work. Although +61 and then the number still works but it's expensive
I thought by warning you not to buy this card for the time being if you intend to phone home, it will save you money and frustration. Simpati Sim Cards work well and the calls back to Aus are very cheap
