Sites like GMail, Facebook and others are starting to get into the habit of requesting your personal phone number to verify site registrations. This to me is dipping into my anonymity just a bit to much, thus I'm looking for some way to keep this at a distance while also allowing me to use those sites. I know Google has a service called Google Voice that will you use a virtual number, but it requires a real number to forward it to. Essentially, I could get by if I had a virtual SMS system that I could have the confirmation codes sent to when the sites send their text messages. Is there a service that will provide easy access to anonymous virtual numbers and text messages to use for sites that require that type of confirmation? I've already tried things like Pinger and TextPlus (using a cell phone emulator) and none seem to work. Is there any sites that could do this kind of thing or is Fiverr the only way?
