I am going to travel to the United States. Please recommend a mobile phone card, which is a SIM card. It can be a local one or a local one, as long as it is the cheapest!

To use Global Communications and then activate international roaming, you need to pre-deposit 3,000 yuan in phone bills. The cost of a call is RMB 8 per minute and a text message is RMB 2 per minute. You can only receive text messages (for free).

When you go to the United States, buy a local calling card (calling card), use the hotel phone to call back to China, and use the 800 toll-free number. The calling card is 4 cents per minute + 75 cents per call. .
