Why do I keep receiving blank messages on my phone?

If someone sends you a message and there is text when you check it, you can rule out that the problem is not the phone call. The number you provided should be a certain network service provider (sp). I suspect that you accidentally customized a certain service of its company at some time, or that the (sp) maliciously secretly hooked up a certain service to you. Yes, it is recommended to cancel immediately. You can first call 10086 to inquire about the situation of this number. If it is true, ask the human service to cancel it for you!
