In Croatia, businesses and individuals are increasingly switching from traditional phone systems to VoIP calling apps. Whether you run a startup in Zagreb, manage a team in Split, or have an office in Rijeka, VoIP provides cost-effective, reliable, and flexible communication solutions.
VoIP, or Voice over Internet Protocol, allows voice and video calls over the internet instead of standard telephone networks. With Croatia’s growing broadband coverage and the rise of remote work, VoIP adoption is accelerating.
This guide will cover how VoIP works, the top apps available in Croatia, pricing, benefits, setup tips, pros and cons, and recommendations for personal and business use.
What is a VoIP Calling App?
A VoIP calling app converts your voice into digital data packets and transmits them over the internet. Unlike traditional PSTN lines, VoIP offers:
- Cost savings for local and international calls
- Mobility across devices: smartphone, tablet, or desktop
- Advanced features like call recording, voicemail-to-email, and HD voice
Popular apps in Croatia include RingCentral, Zoom Phone, 8×8, NFON, Aircall, and MyNetFone Croatia.
How Does VoIP Work in Croatia?
The process is simple:
- Speak into your device’s microphone
- The app converts your voice into digital packets
- Packets are transmitted via broadband (fiber, DSL, or mobile data)
- The recipient’s device converts packets back into voice
Croatia’s internet infrastructure, particularly in Zagreb, Split, and Rijeka, supports high-quality VoIP calls with minimal latency.
Compliance considerations:
- Data hosting & GDPR: Ensure your provider stores data in the EU to comply with GDPR
- Number provisioning: For Croatian numbers (+385), providers must follow local telecom regulations
