The mobile phones that can be used in the United States are tri-band mobile phones (tri-band refers to 900M, 1800M and 1900M GSM). If your mobile phone system meets the requirements, you can open an international roaming call yourself.

Most public telephones in America are pay phones. There are two ways to make public calls: coin-operated and calling cards.

To make an international call back to China from a local telephone in the United States, the dialing method is: international live broadcast (0 1 1)+ country code (86)+ area code (2 1)+ telephone number (12345678). If your mobile phone has applied for international roaming, call back to China as above.

To make a long distance call in the United States, dial 1+ area code (2 12)+ phone number. Make a local call, just dial the local number directly.

If you don't have an international roaming phone, I suggest you buy a local calling card.
