yes, I do have vonage Unlimited to Nepal, it cost you around $69.00 per month including taxes. and its not free to Nepal Mobile, its free for Landlines and CDMAs. Call quality is just Okay...... It can be really good sometimes or bad every once in a while....... I guess it depends on call traffic on Nepal telecom or other providers in nepal.
Yes, every once in a while i hear those annoying messages..... but i just try again and it gets connected.
Next good thing is you can use your cell phone to get access to Vonage unlimited calling. If you use iphone or android phone, they have a program called "vonage extension" that can access your contact lists on phone and dial the number or you can dial manually (no need to enter pins). Or if you simple phone you can get aceess no and set your own pin, means you dont have to be at home to use your free international call through vonage.
I got it about 5 months ago...... Before that i used to get $30.00 monthly plan from raza.com which was preety good and i realized i was recharging it every 15 days means i was spending $60.00 per month to get about 600 minutes.
After getting vonage i dropped my cell phone minutes to lower minutes per month saving some money there as well coz whenever i make a call from home i use vonage instead of my cell.
So far I am happy.
PS: they send device for free, no cost to install and there is no contract......... if you dont like it... you can disconnect anytime and you dont even have to return the device.
Need more help, let me know.
