I use cricket wireless service.
I used to have a AT&T 640, the visual voice mail does not work. It is a convenient feature I really miss.
I bought an unlocked 950xl through the Black Friday BOGO deal, then purchased a new Cricket SIM card from amazon.com (the SIM card for 640 is too big for 950XL). I followed the instructions from the cricket wireless website to activate the SIM, and transferred my 640 phone number to the 950xl. Then the visual voice mail just works.
Here is what I understand. As long as the IME number of a windows phone is in Cricket Wireless's database, visual voice mail will work. The SIM activation step entered my 950xl's IME number into their database.
As to my AT&T 640, since Cricket Wireless is a subsidiary of AT&T, the cricket voice and data service just works on any AT&T phone. So when I retired my old Cricket 630, I simply moved the SIM from it to the 640, and never actually input the 640 IME number into their database. I hope I learned that before.
