Hello @Sweetpea97, I hope you're doing well.
For issues with your voicemail access and the pin, you will need to contact your carrier directly as this is part of your phones service and not the phone itself. I'd recommend reaching out to your carrier for support on this.
Take care.
Hey there @Beachgirlsfurbabies, I hope you're doing well.
In the future, please create a new topic for any questions you have if they do not relate to the topic of the thread you are posting in.
For your issue, I'd recommend going to: Settings>Battery and device care>Device protection>Scan phone. This will scan your device for any suspicious activity or malware.
Take care.
