I am on oranges in Israel unlimited plan. (locally and to 42 countries). I wanted to have as well that people from the states can call me on a local US number, and if it wouldn't cost much.
Basically there is a website
www.localphone.com where they have that you can get a US number for a one time fee of $3.00 and then a monthly $0.99 fee. And then it costs $0.06 cents per minute.
So I wanted to get around the $0.06 cents per minute. Becaus even if someone calls me, and I don't pick up (and I get the call, and can return it for free) but if it goes to voicemail, or if the phone is off, or in a no service area it will still cost. And trust me it adds up pretty quick!
So I came up with an idea to forward my google voice to this local number, and have everyone only call GV. and like this whenever someone calls it will ring on my phone and have the advantage that It will only go to the GV voicemail.
Now like this I never pick up the phone when someone is calling me from US, and return the call right away. And never get charged for this service! Except for the $0.99 a month! Also I am get free voicemail transcriptions.
Everyone in the US loves it!
