While staying in Melbourne in February 2017, I chose to buy a mobile hotspot to stay online with the various devices I had with me. As in 2016, I chose Vodafone as the service provider, since they seem to offer the best network, coverage, value for money and data options.
I bought a 4G pocket wifi R216H mobile hotspot with a 30 day 8GB prepaid option for AUD 59 (about USD 45 or EUR 43). Any additional recharge would be AUD 30 for 8GB of 4G data.
In the U.S. I just recently used a AT&T GoPhone prepaid plan, offering 4GB with unlimited national calls and SMS for USD 45 . In Germany, Vodafone’s corresponding 5GB prepaid plan would be around EUR 35 depending on the service provider. So in terms of mobile broadband, Australia is a good place to be.
During my time in Australia the pocket wifi mobile hotspot never failed me. I used it with up to 4 devices (2 iPhones, 1 iPad Pro and an Apple Watch) both in Melbourne and on the Great Ocean Road. The advertised 10 hour battery life is easily matched and with mobile battery packs this can easily be extended to have a full day of mobile internet access with just one SIM card and one prepaid package.
So for anyone traveling in Australia, I can definitely recommend both Vodafone as a decent service provider as well as the pocket wifi devices they offer in combination with their prepaid data plans.
