iPhone Voicemail Full
I have an IPhone X. I have deleted all voicemails and also then cleared them, but still callers receive the message that my mailbox is full. I was reading a similar question from 2017 and there was no resolve. My service provider is Verizon. The thread from 2017 stated that Verizon indicated they were unable to reset voicemail. Has anyone else had this problem recently? If so, what is the fix?
