GrandCentral gives you a phone number that will be yours “for life.” Service began in 2005, but I only became aware of it when Google acquired the company back in July. When you get a call through your GrandCentral number, all the phones of your choosing will ring, and you are free to pick up on any of them. In case you don’t want to answer, you can send it to voicemail, and access it online or by phone. In addition, you can customize your ringback tones, your greetings—per group or person, or activate spam filtering.
My invite came only last week, but I’m already updating all my friends with my new number. For now, it doesn’t have SMS messaging (not that my cell plan paid for it anyway) or an easy way to make an outgoing call, but it’s saving me minutes, and that’s all I care. I have eight invites left, so if you want one, drop me a line. Available while supplies last.
