Additional information

  • The 4G/5G mobile internet can be faster and more stable than Wi-Fi.
  • If you are on a phone call on MiiTel Phone Mobile, which was started by Wi-Fi, and move to an area where the Wi-Fi does not reach, please note that the app will not automatically switch to 4G/5G mobile internet, and your call can get disconnected.
  • Since MiiTel Phone Mobile is an app that is supported by Apple and Google, you may experience some delays in the services due to the network environment or other reasons, and please note that there is no guarantee for receiving 100% of the phone calls. Therefore, we recommend you also use the PC version of MiiTel services (MiiTel Phone Desktop, MiiTel Phone Chrome Extension, MiiTel Phone for Salesforce) with MiiTel Phone Mobile.
  • Please note that the sound quality can be low when using Bluetooth devices (headsets, earphones, etc.).
