Short-term travel to Australia, mobile phones need to access the Internet, and phone calls and text messages are rare. What kind of card is the best? Where can I do it?

Australian local telephone companies include 3G, optus, Telstra and Vodafone. Optus and 3G are very popular among students. Relatively speaking, Optus has more packages and discounts, while Vodafone is relatively expensive. The above are suitable for long-term residents studying in Australia. If it is a short-term trip, it is not recommended to apply for a local card. Generally speaking, if you apply for a card, the longer the time, the greater the discount, so it will not be converted in the short term. Moreover, if foreigners apply, there are procedural problems and it is very troublesome. In China, you can rent a 3g router in Australia, or you can rent one to carry with you. You can rent it on the supporting website. Australia has 1GB traffic every day, which is very suitable if you surf the Internet more. They have a counter at Pudong airport. You can pick up the goods directly there after processing them on the website, and then send them back there when you return to China. If it comes from other places, you can receive the goods and return them by express delivery. The price is also very close to the people. If you have friends with you, you can use them. One device supports 3 to 5 Internet terminals. Remember to adopt it when you are satisfied.
