Can I see caller ID and SMS on the iphone 6s blacklist?

After being blacklisted, you can't see calls and text messages.

Blacklist of mobile phones is an effective means to prevent harassment. Don't set it casually, so as not to delay important things. If someone bothers you, you can warn him. If you don't listen to the warning, you can call the police If you don't want to receive spam messages, you can block messages from strange numbers.
