Free vs. Cheapest VoIP Phone Services β Whatβs the Difference?
In addition to paid but cheap VoIP services, there are completely free tools, such as Nicegram, WhatsApp, or Telegram. However, such services are convenient for personal communication but they are too simple for business.
Their main difference from paid VoIP services is that they do not offer stable connections, professional features, or support. There are no multi-channel numbers, no answering machine, and no integration with CRM. Everything is based on convenience, not reliability.
At the same time, cheap VoIP services such as Sonetel or Calilio cost up to $15 per month and provide benefits such as stable connectivity, voice menu, call forwarding, call recording, advanced settings, and round-the-clock support.
