Free Call to Slovenia from US — $0.13/min (2026)
Call Slovenia for $0.13/min with BubblyPhone. WhatsApp + Viber popular. Country code +386 (NOT Slovakia +421!). Ljubljana 1. Small (2M pop) but well-connected EU member.
Yes: calls to Slovenia are free app-to-app on WhatsApp and Viber, both popular there, and on Messenger or FaceTime. To call a Slovenian phone number, BubblyPhone costs $0.13/min, $7.80 for a full hour. The country code is +386 (Ljubljana's area code is 1); don't confuse it with Slovakia's +421.
Whether you're calling family in Ljubljana, friends in Maribor, or business contacts in this Alpine nation, here's every option for calling Slovenia cheaply or for free.
Slovenia vs. Slovakia — Not the Same!
Slovenia (+386): Capital Ljubljana, borders Italy and Austria, Alpine country, 2 million people, formerly part of Yugoslavia.
Slovakia (+421): Capital Bratislava, borders Austria and Hungary, Central European country, 5.4 million people, formerly part of Czechoslovakia.
The confusion is so common that the two embassies reportedly meet monthly to exchange misdelivered mail.
Free: App-to-App Calls
Both people need the app and internet. No charges, no limits.
1. WhatsApp — Widely Used
WhatsApp is popular in Slovenia, especially for personal communication. Carriers Telekom SL, A1 SI, and T-2 provide excellent mobile data coverage across the country. Free voice and video calls work great.
2. Viber — Also Popular
Viber has a strong presence in Slovenia — similar to other former Yugoslav countries where Viber gained early adoption. Many Slovenians use both WhatsApp and Viber, sometimes preferring Viber for group calls and communities.
3. Facebook Messenger — Common
Messenger is used alongside WhatsApp and Viber. Slovenia has high social media penetration, and Messenger is a go-to for casual communication and connecting with acquaintances.
4. FaceTime — Moderate
iPhone has reasonable market share in Slovenia — around 25-30%. Samsung leads overall, but Apple is popular among younger professionals. FaceTime works well for personal calls.
Calling Slovenian Phone Numbers
Slovenia is moderately priced to call:
| Service | Mobile Rate | Landline Rate | Notes |

| BubblyPhone | $0.13/min | $0.13/min | Browser, iOS, Android |
| Google Voice | $0.37/min | $0.18/min | US Google account required |

| AT&T / Verizon | $2.00-3.50/min | $2.00-3.50/min | Up to 27x more expensive |
Our honest take: Google Voice ($0.10/min mobile, $0.03/min landline) and Rebtel ($0.09/min) are cheaper than BubblyPhone ($0.13/min) for Slovenian phone numbers. For free calls, WhatsApp and Viber both work well — Slovenia has excellent internet.
