There are always overseas SMS and WeChat to send things.

No, please be careful to receive foreign text messages that claim to be relatives, especially those that have not been communicated with this relative before. Because in the Internet age, there are more and more means of online fraud, and criminals will cheat your personal information and property by pretending to be your identity. Therefore, when you encounter text messages of unknown origin, you should be vigilant, don't trust each other easily, and don't add social software such as WeChat at will. If the other party insists that you add WeChat, refuse carefully and don't disclose personal information and assets. If you think this person who claims to be a relative is a real relative, please further confirm the true identity of the other person through other channels, such as telephone, email or other reliable communication methods. Don't provide or disclose personal information at will before confirming the identity of relatives, and protect your privacy.
