What services does the mobile phone for studying in the United States or qq WeChat provide? Do you have to go abroad to receive short messages? What does it have to do with bank cards?

On the second day of your visit to the United States, you can go to the communication operator (at & amp； T or T Mobile) store to buy an American phone number, let them bind it to your phone card for you. If your mobile phone doesn't work in America, buy a new and cheap one. The usual package is 60, 1 month, no calls in the United States, no text messages around the world, and 2-4G Internet access. Then you go to the supermarket to buy a calling card for calling China, and you can call for more than 2 hours for 5 yuan. If you don't need to surf the Internet, there is a 25 yuan 1 month package. In the United States, all mobile phones with Internet access use WeChat and qq. China students studying in the United States all use WeChat. If you have wifi in your dormitory in the United States and generally have free wifi on campus, then you can choose a $25 package. But if you often wander off campus, you need to use Google Maps on your mobile phone. Then you still need some internet traffic. These have nothing to do with bank cards.
