Australia Prepaid SIM Card Unlimited Calls/SMS + Internet Data(Optus Network) (20 Days_6GB)

Got both the 28 days - unlimited and the 20 days - 6 GB sim cards for use in Tasmania and Melbourne. Set up activation for them as directed a few days before our departure and they worked seamlessly for our trip. At one point, we got a warning message that the unlimited SIM was almost out of data but this was ignored and it continued to work. Nice to hit the ground running with local numbers and internet. Buying before you land means that you can also insert the SIM cards at the start of your flight, rather than when you are bleary and jet lagged.

My husband and I ended up ordering two of these for our 2-week trip to Brisbane. After reading the reviews we were a little on the fence, but we decided to just go for it. And, I'm so happy that we did! They worked from the moment we got off the plane in Australia, to the moment we left. There were no times in which we had to go without our phones, which was a huge relief, considering we heavily relied on Uber to get around. This was a much better deal than paying for an international plan with our carrier, so I would highly recommend this option to anyone considering it.

Works perfectly - just needs to be activated beforehand. They say 3 days but 48h was enough in my case.Pricing is in line with prices in AustraliaFast and good shipping

We bought two of these to use in our unlocked iPhone XR and Galaxy Note10. We traveled from the US to Australia. Followed the activation instructions a few days prior, and they worked perfectly as soon as we landed. Would definitely buy them again!
