I used to received voicemail notification (from number 18, saying I have received 1 voice msg) when someone leave me a message. Recently I stop receving these notification until people told me they left me messages. I have missed important messages and would need to check into VM time to time to make sure I catch up all the missing messages. have done some troubleshooting (see below), but still no luck:
1) Clean up all the messages saved on the Sim card (all the msg from number 18)
2) Restarted my cell phone couple times
Phone: Samsung Galaxy S3
VM: mini VM, no data required.
I haven't tried reset my phone, this would be my last reserve.... Just wondering if anyone have similar situation and how can you fix it?
