T3 establish emergency contact. Is there a message?

T3 set up an emergency contact by SMS, because you have already set him as an emergency contact. Since it is urgent, I will definitely send you a message. When you contact him in an emergency, I will send you a text message at any time as soon as the phone call is over, and you will receive both a text message and a phone call from the emergency contact. This is also for double insurance, so that you can double insurance. It's also convenient to check, and it's not that hard.
