My mobile phone often receives messages from 10663355776, all of which are greetings. Where is the information source?

Maybe your friend sent you a message on the computer. Now many websites provide free information, that is, use their websites to send you a message for free. However, one disadvantage of this short message is that it doesn't display the sender's number, so you don't know who sent the message unless he wrote down his name. Hehe, you receive this message just like a normal message, and there is no other charge. Don't worry.

I often receive them, too.

It's from a friend on the computer.
