I am consulting now days and my iPhone is used for both personal and professional purposes. Several weeks ago I complained in an article about having to use my personal phone number and voice mail for business.
A kind reader suggested that I try the new Google Voice service. I did and am still learning it but it has some interesting feature that I find handy for mobile workers.
Google let me pick a phone number from any location in the USA. I thought about getting a New York City number to be clever, but being clever generally gets me in trouble so chose a Boise prefix and number.
Once I had a Google phone number, I was asked to forward it to my mobile, home or work phone. So now one number can follow me to any location, phone or mobile device. My iPhone now has 2 phone numbers, one that came with the iPhone and now the Google number. I also have 2 different voice mails. One that came with my iPhone service and Google voice mail.
It gets better, Google transcribes any voice mails and sends it to my email address. I could be in New Zealand but read my voice mails through any Internet connection.
I know there is a lot more to learn about Google Voice, but I need to find a different issue to complain about now.
