How to solve the problem of wireless internet access by mobile phone after traveling to the United States for 45 days?

Taobao or the airport rents wifi.

When booking a hotel, it is best to ask if there is an extra charge for hotel Wifi. Because of the WiFi in American hotels, generally only the wifi in hotel rooms below 3 stars is free. Many high-end hotels charge for wifi. 1 day charge 19.99 USD is very common, and it is still charged according to the number of access terminals. That is to say, if you have three terminals surfing the Internet with wifi, 1 day is 3 * $ 19.99. However, wifi in all hotel lobbies is free, so you can go to Internet cafes to surf the Internet.

Restaurants and cafes: In China, most people now use their mobile phones to surf the Internet after ordering food. In the United States, fast food chains and Starbucks are free, and many restaurants are also free. Some just ask the service desk for the password. Every Starbucks will provide free WiFi access, but you can't go to Starbucks every time you want to surf the Internet. If you go to other restaurants and don't know if there is free WiFi, you can ask your local acquaintances first.

Airport: Although the airport is not listed in the ranking of public places in the wireless Internet signal set, most of the most boring and difficult time in travel is spent in the airport waiting for a connecting flight or plane delay. In addition, most airports around the world provide free wireless Internet access. The airport is so big, how can we determine where the signal is? Before you go to the airport, you can find a list of specific places where you can get free wireless internet access at major international airports, even near the boarding gates of several terminals.

Precautions: Pay attention to the routine items and personal safety that you carry with you.
