Setting up the Sonim XP3, XP3plus, XP5s, and XP5plus devices

  • Updated

This article is written for: Zello Work Zello Friends & Family.

The Sonim XP3XP3plusXP5s, and XP5plus do not support the Google Play store, so you won't be able to download Zello onto them directly. Additionally, as a security feature, only apps that are pre-approved by Sonim will run on these devices. If you attempt to download an app without a Sonim signature, the installation may fail, or it may not work properly. There are three methods to load Zello onto these devices: 

  1. Direct download of the Zello for Sonim APK
  2. Contact Sonim Support 
  3. Virtual Download via the Sonim CLOUD management software

Please note that regardless of the method you use, the .apk currently supports Android 5.0 and higher. 

Method One: Direct download of the Zello for Sonim APK

The simplest method is to download Zello directly onto your Sonim device. To ensure that Zello will install and work properly, you must download the most recently signed .apk file with Sonim's signature from our website. To facilitate download, copy the download link and send it as an email or text message to your device:

During installation, you may see a screen requesting for you to verify that you want to install an app downloaded through your browser. Accept this request in order to proceed with the installation. 

After installation, sign in with your Zello Work network name, username, and password. The easiest way to do this is with a Sign On Link from your Zello Management Console. 

Method Two: Contact Sonim Support 

If you are demoing Zello on Sonim products, the quickest way to get the app onto your device is by reaching out to Sonim’s Demo Support team. Please reach out to with the following information: 

  • Your Company Name
  • App name (Zello) 
  • Device Model(s)*
  • Device IMEI(s)*

Once Sonim has received your email, they will use the IMEIs to download the app to your phone. Typical response time within business hours is >2 hours. 

*Device Model and IMEI can both be found by going to Settings > About Phone from your Sonim device. The fields you are looking for are Model & hardware and IMEI.

Method Three: Virtual Download via the Sonim CLOUD management software
