VoIP industry is full of new companies that offer very cheap rates when they launch and then we do not hear about them after a few months. There are only a few major players who have survived for a long time including Rebtel, LocalPhone, Vonage and a few others. We have been following Jumblo for a long time, they have survived with unbelievably cheap rates to most destinations without compromising on phone call quality.
Jumblo provides free international calls to many countries, but if your destination was never given absolutely free calls by any voip provider neither does Jumblo. However, their call rates are pretty cheap and thus we recommend you to try them next time around when you need to recharge.
Jumblo Call Rates for International Destinations
We here at CorVoIP believe in giving out the true information, as their is no gain by claiming that a particular voip provider provides cheapest international calls. If you visited Jumblo earlier you would have mistakenly assumed that they provide cheap calls to India at 0.07 cents. Well, let us have the opportunity to clear this myth. Cheap international calls by Jumblo at 0.07 cents is true, but this is in EURO and when you convert it to USD and add VAT their cheapest call rates to India come up to $0.012. It is still cheap though.
In short, they sometimes advertise prices in Euro, so do the conversion yourself to find out the final price.

How to make Calls using Jumblo
We recommend try making calls from your phone over wifi. We use it personally and it rocks. You could even make calls without any computer, or headset. Go to their website and enter your own number and your destination number. You and your party will both get a call from them, and you will be connected to each other. This works for all of their free countries. The list is not exhaustive but a lot of destinations are in Jumblo’s list for free countries.
Making United States a free country does not make much sense though as the phones in USA do not have free incoming calls. They end up paying for their minutes regardless. However, if you are in one of the other Jumblo’s free countries then it makes sense to make free calls to USA, which again can be done using Free Landline Phone by Google Voice and ObiHai.
Jumblo also allows you to use their phone app to make calls, so if you are not interested in spending your minutes, you could opt for wi-fi or 3G based calling through the app.
