Portugal is rapidly adopting VoIP (Voice over Internet Protocol) technology across businesses of all sizes. From startups in Lisbon to multinational offices in Porto, VoIP is replacing traditional landlines due to its cost-effectiveness, flexibility, and advanced features.
In this guide, we’ll explore the best VoIP calling apps in Portugal, explain how VoIP works, compare features, share case studies, and help you choose the ideal solution for your business or personal needs.
