The other party has set up a voicemail. Can he receive my text message? How can I crack it for him?

Yes, voice mail is a missed call reminder service he opened in the communication center. When the phone is turned off, when you call him, it will show that it has been sent to the voice mail. This is a message. You can leave a message for him after the beep. He will receive a short message indicating a missed call, which contains a voice message link and a phone number. He can hear your message by dialing the number once, but if he has a lot of business and calls, he probably won't go back to listen to the message and the message can be received. As long as both sides don't stop, I hope I can help you!
