I am unable to access my voicemail all of a sudden. it was working fine, not sure what changed. When I press 1 and call it says "USSD code running" and then "Connection problem or invalid MMI code". I have tried going into voicemail settings and in the set up spot putting my phone number like what I read on other peoples chats with this issue and it is still not working.
If I hold down the 1 button then it works.
try reboot the phone, then click Reset all networks, it should push the voice mail number to you again
if not, you can try one of the numbers here, call and you can get VM there
for any number it works, you can then re-program it back on your phone. Go to phone dialer, click the menu, select voicemail and update voicemail number
If none of those helps, please submit a ticket with CS Agent here:
