Free Call to Sri Lanka from US — $0.35/min (2026)
Call Sri Lanka for $0.35/min with BubblyPhone. WhatsApp popular, Viber also used. Country code +94. Colombo 11. UTC+5:30 (same as India). Dialog, Mobitel, Airtel LK, Hutch carriers.
Calling Sri Lanka costs $0.35/min with BubblyPhone — $21.00 for a full hour. WhatsApp is widely used, and Viber also has a strong presence. The country code is +94, and Colombo's area code is 11. Sri Lanka shares the same time zone as India: SLST (UTC+5:30). The country has been recovering from a severe economic crisis in 2022 that affected internet and telecom reliability.
Whether you're calling family in Colombo, friends in Kandy, or business contacts in Galle, here's every option for calling Sri Lanka cheaply or for free.
Free: App-to-App Calls
Both people need the app and internet. No charges, no limits.
1. WhatsApp — Most Popular
WhatsApp is the dominant messaging app in Sri Lanka. Free voice and video calls work well in urban areas. Dialog, Mobitel, Airtel LK, and Hutch all offer affordable data plans. WhatsApp is the go-to for personal and increasingly business communication.
2. Viber — Also Very Popular
Viber has a strong presence in Sri Lanka — more so than in many other Asian countries. Many Sri Lankans use both WhatsApp and Viber. Viber Out (paid calling to phone numbers) is also used by some for international calls.
3. Facebook Messenger — Common
Facebook is popular in Sri Lanka, and Messenger is used for voice and video calls alongside WhatsApp and Viber. Some Sri Lankans prefer Messenger for connecting with acquaintances and extended family.
Note: Sri Lanka temporarily blocked social media during the 2022 economic crisis protests. Service has since been restored, but be aware this could recur during political instability.
4. FaceTime — Limited
iPhone market share in Sri Lanka is relatively low — around 15%. Samsung and budget Android brands dominate. FaceTime is used mainly among wealthier demographics in Colombo.
Calling Sri Lankan Phone Numbers
Sri Lanka is expensive to call:
| Service | Mobile Rate | Landline Rate | Notes |
|---|---|---|---|
| BubblyPhone | $0.35/min | $0.35/min | Browser, iOS, Android |
| Google Voice | $0.14/min | $0.06/min | US Google account required |
| Rebtel | $0.10/min | $0.05/min | Unlimited plans ~$10/mo |
| AT&T / Verizon | $3.50-5.00/min | $3.50-5.00/min | Up to 14x more expensive |
Our honest take: BubblyPhone at $0.35/min is the most expensive option for Sri Lanka. Rebtel ($0.10/min) and Google Voice ($0.14/min) are significantly cheaper. A 60-minute call costs $6.00 with Rebtel vs. $21.00 with BubblyPhone. WhatsApp and Viber are free — definitely use those first.

Calling a Sri Lankan mobile number
