Time difference in sending short messages abroad

Short messages must be transmitted through many servers. Among them, it will be sent to the SMS Integrated Service Center of China Mobile by the SMS Service Center in your sending place. Then transfer to the SMS service center abroad, then go to your friend's mobile phone area and download it to his mobile phone. This process has four nodes. There may be a delay. In addition, international short messages generally only support English. If it is in Chinese, it may be rejected by foreign SMS service centers. They don't support Chinese format there. So international SMS is still not safe. Hmm. How interesting
