How to send a text message to a foreign mobile phone after making an international call? How to confirm that SMS has been received abroad? thank you

Hello, if you are a Beijing mobile number, the way to send a short message to a foreign number is: international long-distance access code (00 or+)+country code (not 86)+ customer number. Send international short messages 1 yuan/message. For example, the country code of the United States is 1, the customer number is 6 15 1234567, and the destination number is 0016151234567 or+1. Cost 1 yuan/article. If it is a prepaid number, the international SMS will be charged in real time, and the fee will not be charged if it is unsuccessful. Please refer to.
