Getting Better Every Day ...  Pou Kao  5 star

I have had my account almost one year now when they supported only 2 countries then..... my job has lots of travel and clients that want to only call a local number which saves me lots of money when I use onoff ......since my original sign up with onoff they have expanded greatly in the last year and services were good then, great now and getting better all the time i log in the service..... i tried about 5 other virtual phone companies and onoff had the best quality in my opinion... I live in Thailand and travel all over Asia and Europe.... this sounds like a AD but this is my honest review... maybe I will get a gift :) Bye for now
