Zebra Mobile Overview

This guide is designed for administrators managing Vocalised services. Administrators can add new users and change Zebra Mobile plans via the Vocalised Portal.

Zebra Mobile gives users a fully functional business mobile line using an eSIM, without needing a second phone. It integrates with your business number and calling plan, letting you manage both personal and work calls from the same device.

About voice-only with background data

The voice-only option includes up to 5GB of background data which works when on a business call.
You can only use one mobile SIM at a time for voice or data, background data is helpful when you are using data on your primary personal SIM and take a business call. For example whilst driving, you may be using mobile data with maps for directions and it won't cut out when you take a business call, the background data service will automatically switch-over whilst you are on the call.

How It Works

The Zebra Mobile eSIM is linked to a user as a telephone endpoint, just like the Webex softphone app or an IP phone. In the Anywhere Portal this will be linked to a generic SIP device.
Users receive a QR code in their welcome email to activate the eSIM which is added from the phones settings. It takes between 20 seconds and 2 minutes per user to install the eSIM
iPhone users have additional settings when setting up the SIM which are detailed in the welcome email. Future iOS updates should remove the need to change these settings when installing an eSIM

Landline and Mobile Numbers

When a number is dialled on the mobile phone, or a contact is clicked, the business landline number (outbound CLI) is presented
You can change the setting in contacts to always dial from your primary personal to your business number as standard for business contacts.
Calls to the business landline number will go to the mobile and calls to the mobile number will also go to the mobile.
SMS works using the mobile number only.
The Mobile number can be used to register for WhatsApp Business, iMessage and Facetime.

SMS and Dual SIM

SMS is enabled by default when used in conjunction with a mobile number
Each Zebra Mobile number includes 1000 SMS per month with a fair use policy
Please see these guides for more information on dual-sim use:
Apple iPhone
Samsung Galaxy
Google Pixel

Setup & Activation

Scan the QR code in the welcome email using the Add eSIM option in phone settings
Follow the recommended settings in the setup video, we recomend you personal line is used as the primary line for voice, data and for iMessage and Facetime (iPhone)
Users can select the Business line as the primary line for voice or data at any time.

User Issues:

If the user needs to move their eSIM to a new phone or to a new user - an admin can reissue the SIM for use in a new phone and new user from the Vocalised Portal, it must be deleted from the old phone first, it is not possible to register the same SIM on two devices. An updated welcome email will be sent with a new QR code.
If the user has lost the phone and is unable to access settings to delete the SIM card, an admin can request a new eSIM from support. Please note, additional customer checks will be done.
Check your phone is on the supported list and the device is unlocked to use other networks.
