Recently Vonage started offering Unlimited Calls to India under its $24.99/m existing plan. Good thing is that the plan includes both landlines and cell phones all over India.
If you are already a Vonage subscriber, make sure you have Vonage World plan to get this great deal. Not sure whether it is automatically done. For me, I did convert to this plan explicitly.
If you are not a Vonage subscriber already, think about it. For $24.99 you get unlimited calling to India (and about 60 countries) and have a landline number to make unlimited calls within US.
Get ONE month FREE.
Vonage initially offered 2 months FREE when you sign up for this service. But now it is back to its original offer of ONE month FREE offer. Get ONE MONTH FREE if you signup by clicking on the image below. If you pay whole one year upfront, you may get an additional 20% off.
