StartACall works in your browser. This means no downloads, no installations, and no app updates. You can make a call from any device with a browser—your work laptop, a library computer, or your phone.
Viber Out requires the Viber app. You must have the app installed on your device. This limits you to devices where you have the app and can be inconvenient if you need to make a call from a different computer.

This is where StartACall truly stands apart. Viber Out is a simple calling feature, but StartACall is a powerful communication platform.
Get real-time AI suggestions during calls. Perfect for sales and support teams. Viber Out has nothing like this.
Launch automated calling campaigns to thousands of numbers. An essential tool for business marketing and notifications.
StartACall uses a simple pay-as-you-go model. You add credits, and they are deducted per minute. Crucially, your credits never expire.
Viber Out uses credit packs and monthly subscriptions. While subscriptions can be good for heavy users, their pay-as-you-go credits can expire after a period of inactivity, meaning you could lose your money.
Stop worrying about apps and installations. Make crystal-clear international calls from anywhere, on any device.
🎉 First call free • No credit card required
StartACall offers highly competitive pay-as-you-go rates, often starting lower than Viber Out for many destinations. Unlike some Viber Out plans, StartACall's credits never expire, which provides better long-term value. The best choice depends on the specific country you're calling, but StartACall's transparent pricing and lack of forced subscriptions make it a very cost-effective option.
