Does the mobile phone have a function that you can't receive other people's calls when you are not in the service area? Can there be a text message to remind who called?

Mobile phones don't have this function, but mobile phones have this service, which is called in different regions. Some are called call secretaries, others are called call reminders, that is, when your phone is turned off, you are not in service area or there is no signal, the other party recently called them to remind them that you have done the call reminder service. When you turn on your cell phone or get a signal, I will send you a message saying that a certain number will call you at a certain time. This service seems to be 2-3 yuan a month, and 5 yuan at most. You can call mobile customer service.
