What is random number texted me hi?

As an AI language model, I cannot provide specific information about a random number texting you "hi" without further context, as there could be a multitude of reasons or individuals behind the message. It could be a friend or acquaintance saying hello, a wrong number, or even a scammer trying to get your attention. It is important to be cautious when interacting with unknown numbers, especially if they ask for personal information or requests that seem suspicious.
