Unwanted calls can be very frustating! There is not a way to see if a blocked number has tried to call or message you. If the blocked number is a VZW customer, they will see a red X in the sent folder with status failed notification. Followed by "Delivery failed. Invalid destination or service blocked at destination". They will also receives a text message alert - "You cannot send messages to destinations that are blocked by the account owner." If a block non VZW customers attempts to send you a message, they will see a green check mark with a "Message Sent" notification but message not delivered to your line.
Addtionally if a block VZW or non VZW number attempts to call you: Call does not go through. The blocked line hears an audio alert " The number that you have dialed has calling restrictions that have prevented the completion of this call. I am confident this information is helpful. Please let me know if you have any additional questions or concerns.
