I have a LG221C Tracfone. When someone calls me it will say that I missed a call but does not tell me that a voicemail has been left if there is one. I get no notification icon or anything. The only way to tell if you have a voicemail is to sign in to voicemail to check. Is the voicemail notification not possible on this phone or do I have a dud phone?

Hi Eric. I just checked the manual but nothing was mentioned regarding blocking calls or text messages. Your best option would be asking your carrier if they have blocking service.
