Affordable Internet in Australia
A prepaid plan protects you from extra charges – you pay a fixed amount, which is often cheaper than roaming fees. Plus, you can buy an Australian eSIM with different data amounts and prices: the larger the package, the lower the cost per GB. For example, with a 50GB plan, the price per GB is $1.47.
Unlimited Hotspot
Traveling to Australia with friends? You can buy one eSIM and share your internet connection across multiple devices. It’s also convenient if you need to work or want to watch movies on your laptop or tablet.
