Tips for clear & uninterrupted calls

Whether you're reaching Slovakia for business or family, three habits keep every conversation crystal clear — and a clean route from TKOS handles the rest.

  • 01

    Use high-quality equipment

    Invest in a good headset or microphone for clean audio. Maintain your gear regularly to avoid static, dropouts, and muffled sound.

  • 02

    Ensure a stable internet connection

    Prefer a wired connection over Wi-Fi when possible, and watch your bandwidth — heavy downloads or streaming will degrade call quality.

  • 03

    Minimize background noise

    Take calls in a quiet space and use a headset with noise cancellation. A short test call before the real one catches problems early.
