My friend is in Thailand, and China Mobile has a GSM mobile phone. How can I text him?

Just like you usually send it in China, provided that your friend has launched a global roaming service, otherwise how can you not send a signal? Our former boss often went abroad on business. He is a cheapskate. If there is nothing important, he wants us to send a message. I just sent it yesterday. He has gone to South Africa.
