I have used Google Voice for almost five years, and TWICE this year, people who have bought new cell phones have gotten my number. And access to my previous messages. This particular person decided to take out their bad mood on my friends, boyfriend and mother by sending them sexual messages. My mother had to block my number.
It will cost you $10 to change your number every time this happens. I have already done this once. This service is supposed to be FREE, but every time someone gets a new phone, I have to pay for it.
Google Tech Support won’t help you either. I posted in their help forum with all my information, and have been on hold with tech support for an hour, with no end in sight to my waiting.
Do. Not. Use. Google Voice. Changing your password won’t help, it is the number you will be forced to change. Don’t waste your time or money!
