How can I get someone to call me? I can't get through, but I can get a text message.

According to the information you provided, if you want a number whose caller ID cannot be connected, you can set it as a blacklist. If you want to show all incoming calls as unreachable, it is impossible for the time being, except that all incoming calls are blacklisted. However, you can open the white-collar secretarial service of 10 yuan/month, and switch to the secretarial desk for manual connection. If necessary, you can send short messages from 5 145 to 100 10.

Tips: The secretarial service is only for 2G/3G users.
