Frequently asked questions

Which is cheaper, Viber Out or BOSS Revolution?

Compare the rate for your destination and number type, then check how many minutes you expect to use. For occasional calls, look at prepaid credit. For regular calls to one country, compare the available plans and any extra access charges.

Can both services call landlines without the other person installing an app?

Yes. You can call supported landlines and mobile numbers. The person you call answers through their phone service; they do not need the same app or an internet connection.

Do I need a monthly subscription?

No. Viber Out offers World Credit, and BOSS Revolution offers a prepaid calling balance. Both also have plans, so check what you are buying and whether it renews.

Can I use BOSS Revolution without internet?

Its mobile app needs Wi-Fi or mobile data. BOSS also offers telephone access numbers you can dial through your phone service. Check carrier charges and the access-number terms for your market.

Can I use Viber Out on my computer?

Yes, through the Viber desktop app. Buying credit on the Viber website is different from placing a call in a browser. If you want browser calling, TelHey is another option.

Which has better call quality?

There is no single winner for every connection and destination. Try the number you actually need to call, check that both people can hear each other, and test the keypad if you need an automated menu.

What happens if I do not use my Viber Out credit?

Viber says World Credit becomes frozen after six months without use and can be unfrozen. There are additional account and number-specific rules, including a 180-day expiry for Japanese numbers. Check its credit policy before buying for infrequent calls.

Can someone call me back through TelHey?

No. TelHey uses a shared outgoing number, not your personal number. It does not receive callbacks, SMS or verification calls. It suits outbound calls where you do not need those features.
