* When using 3G/4G/5G/GPRS/EDGE:

  • When using Teliophone via 5G/4G/3G/GPRS/EDGE, the mobile network operator will charge you for any mobile data transmitted. Using mobile data overseas may result in higher costs!
  • Broadband telephony is dependent on the available bandwidth and response time. A data speed of 3G or higher is usually sufficient. Unfortunately, it is difficult to guarantee speed and response time for data transmitted via 3G,4G and 5G which may affect call quality.
