What SMS command should I send to close international roaming?

Yes, you can edit the short message "6763" or "QXMYQX" as 1000 1 to apply for closing roaming rights in international, Hong Kong, Macao and Taiwan regions. "International roaming" means that mobile phone users can continue to use their mobile phones for voice, SMS and Internet communication in other networks in other countries and regions after leaving their home networks. At present, China Telecom has opened CDMA and GSM international roaming services with operators in more than 200 countries and regions around the world, and the roaming access range is still expanding. In these countries and regions, you can continue to use CDMA or GSM mobile phones for communication.
