Pay as you go or subscribe?
Start by comparing prepaid credit.
For a one-off call, compare the credit you must buy as well as the cost of the minutes you use.
The figures compare usage cost with global plans only. Credit purchases, single-country plans and carrier fees can change the result.
Approximate break-even rate for 10 minutes:
- Rebtel
- 120¢/min
- vs. $12.00 global plan
- Viber Out
- 59.9¢/min
- vs. $5.99 global plan
Below this rate, prepaid usage costs less. Monthly plan price ÷ 10 minutes; included destinations and number types only.
Call Quality and Internet Requirements
Rebtel
- Your phone
- Local line
or internet - Their phone
An extra option when internet is weak.
Local access must be supported where you call from. Carrier service and local-minute charges still apply.
Viber Out
- Your phone
or desktop - Internet
Wi-Fi / data - Their phone
Your connection needs to stay stable.
The recipient needs phone coverage, not internet. Mobile data and roaming costs are separate.
