Swedish based voip company Rebtel has announced that it has acquired Free World Dialing, a mobile calling application, from Talkster for an undisclosed amount. The company notes that under the agreement, Rebtel will now carry all of Talkster’s international calls and Free World Dialing customers will now have access to unlimited free international mobile calls between 52 countries.

The joined services will now offer customers a quick and easy way to call internationally from your mobile phones. To use, customers sign up for a free account, enter an international number into the contact form and receive a unique local number to store to their phone. The principle is that Rebtel will connect the local number to the international number through the internet, costing the customer only pennies instead of traditional international rates.

While former Talkster customers mainly used the service for international mobile calls, they will now have access to several additional Rebtel services, including Rebtel Computer Calls as well as Rebtel SMS for international text messaging.

RebTel is a mixture of current voip providers. It works like Jajah since it assigns a local US number to any of your contacts. Unlike Talkster, no call back is necessary. Nevertheless, the callback option is available for some countries so it would work like Talkster and the call could be much cheaper since you would pay the local US call only. As Rebtell assigns a local number to each user, your contact can easily call you back at his convenience. A rate of $ 0,018/minute is debited from my Rebtel account in this case.

Sample of total cost:
- landline in Italy: $0,10 + $0,019 = $0,119 / minute
- mobile in Italy: $0,10 + 0,195 = $0,295/minute
