Don’t worry! You can still perform an outbound call even when you’re not connected to any Wi-Fi or run out of your mobile data. Instead of Wi-Fi or mobile data, you can use Omni Hotline via Cell Service feature. Omni's Cell Service allows you to make calls using your telco's cell service.


We also recommend using this feature when you're facing call quality issues when making outbound calls via Wifi or mobile data.

However, certain features like call recording, call transfer won’t be available when using Cell Service.

You can change from using Wi-Fi or data to Cell Service by following these simple steps! 

  1. Open your Omni Hotline Mobile App

  2. Go to Settings

  3. Select Outbound Call Method
