Per this help document, you could access voice mail by
"Bring up your Phone app, access the dial pad, and press and hold 1. Follow the prompts to input your password and you’re in."
P.S: Please mark this as solution if it helped you. Thanks.
Thank you for trying, but that is not working. I get the following error message when I press and hold 1
"There's no SIM in your phone, so you can only make emergency calls"
I also tried dialing *86 and I get the same message.
