I know how important it is to receive calls and messages, especially from family members. Thank you Ballplyr14610 for your suggestion.
FB1, is the family member also with Verizon Wireless? Or, are they with a different carrier?
I ask this because normally, if you are having problems communicating with just one number, the issue could very well be with the other line. If their service is with another carrier, please have them contact their carrier for troubleshooting.
When this person calls you, do the calls go to your voice mail or do they hear an error message? When messaging you, does their phone act as if the message went through, but you just don't receive it?
Are you able to call this person and send them messages with no problem?
If you are still having issues with this number, please feel free to send me a PM with your name and phone number. I will be happy to assist you further.
Thanks so much!
