I've been experiencing this for quite a while. It started on my Nexus 4 and has continued and gotten more frequent on my Oneplus.
I get the voicemail notification, icon and notification light. Multiple times repeatedly in a short period of time, there is no new voicemail.
Has anyone ever had this issue and what can be done to fix it?
I tried having Fido reset my voice mailbox but that didn't work.
Thanks in advanced.
It may aslo due to this issue here:
If the sms of voicemail notication is save in the sim and cannot be deleted, this issue may happen.
Could you try to call this number to retrieve your voicemail? +1 416 821-6549
If you have swapped your phone, I sound like our backend issue or sim card issue.
How long have you been using your current sim card?
