What is Vobi?

Vobi is a free mobile application based on Session Initiation Protocol (SIP) that allows you to make and receive calls using your mobile phone, at extremely low call rates. Vobi offers many benefits such as high-quality voice and video calls, full integration with phone’s contact address book, conference calling, call recording, call transfers and more!

Vobi can be used by either home users or businesses and allows you to direct calls to your home or office landlines from your mobile phone, and vice versa. This means that you can always be available to talk as your mobile phone essentially becomes a part of your home and/or office phone, provided you are in a mobile covered area.

If you are often making calls, locally or internationally, then Vobi is definitely something to consider. We know that telephone bills are becoming more expensive while internet packages are constantly getting cheaper, so you will be cutting down major costs while maintaining your call durations.

According to the Independent Communications Authority of South Africa (ICASA), the total number of 4G/LTE device subscribers in SA in 2018 was over 12.6 million. Coupled with the fact that South Africa has some of the most expensive data rates in the world, once can immediately see the benefits of a free mobile calling application. Users of the app can enjoy low call rates across all South African networks as well as international networks, allowing you to avoid ridiculous roaming charges. There is also an uncapped option if you typically make calls more time than the average person.

With 3Gi Internet Services, the standard subscription will cost R25 per month with rates from as little as R0.45 per minute. For more information, visit
