What's with the text message from the victim?

Media reports: Lesley Emerson, a foreign grandmother, liked to chat with her family by text messages before her death. But at the age of 59, she died because she could not overcome her illness. The family decided to bury her mobile phone with her. Emerson, a 22-year-old granddaughter, often sends messages to her grandmother telling her about the situation at home. Unexpectedly, one day three years later, the text message actually replied. The family felt a little creepy, and the letter said, "I'm watching you. You can overcome all this and you will be fine."

Finally, the investigation found that the reply was obtained by a man when he changed his number recently. The man apologized and said, "I thought it was a prank." Then the family found the communication company to which this number belongs, because the family had confirmed with the communication company when they buried grandma that this number would not be used by anyone again. I didn't expect to sell it again three years later.
