How to send text messages when roaming in America?

When roaming in overseas mobile networks, SMS is sent in the same way as in China. Just enter the other party's number directly in the receiving number column:1; Send to Chinese mainland mobile phone: directly enter the mobile phone number; 2. Send to Chinese mainland PHS: 0+ domestic long-distance area code+PHS number; 3. Send to local mobile phones or mobile phones in other countries and regions: 00+ country code+user number. Broadband on demand, fast thinking. The official account of China Telecom's Guizhou customer service WeChat can directly handle the keyword "Broadband on demand", which is convenient and fast. Customer service 40 will answer your questions.
