Mint Mobile is the telco that I have used for a long time. Before this, I also used T-Mobile, Cricket, and different telecommunications, but in the end, I still use Mint telco for a long time! And the application number does not need SSN, which is very suitable for international students! If your mobile phone can support e-sim, you can even set it up two or three days before departure, and you can use it directly when you land! (Very convenient, while keeping the sim card of the original country)
If you just came to the United States, the most troublesome thing is to get a phone number. It is very troublesome to think of going to a telecommunications store. You will also need a number to open a bank account! Fortunately, all Mint applications are online, and they will be sent to your home in about 2-3 days after the application is completed!
