  • Cross-platform synchronization: Supports mobile, PC, and web versions, chat history is stored in the cloud.

⚠️ Warning:

If you cannot message non-contacts after registration:

  1. Search for the bot @SpamBot
  2. Reply as prompted:

No, I will never do any of this.
But I can’t message non-contacts.
