How can I access the Internet on my mobile phone in Australia? Is the wifi in the hotel there free?

You can buy a local card if you want to use your mobile phone to access the Internet in Australia. I don’t know what you are going to Australia for, whether it is to study abroad, work or travel. If you are staying in Europe for a long time, it is recommended to apply for a local phone card directly. A long-term package is more cost-effective. . It's a different matter if the author is traveling to Australia. It's not worth wasting time to apply for a local card in a short period of time. In hotels, there is free wifi in the lobby (depending on the size, it is usually available), but Internet access in the rooms is basically charged. If you have requirements for mobile Internet access, you can actually rent an Australian 3G wireless router in China and take it there. You can do it on the Youbanban website. It is rented together with the card. Australia has an unlimited data package. It is very cost-effective to rent for short-term travel. Very convenient and not expensive. Remember to accept it if you are satisfied.
