# How To Enable the eSIM Ingetraion with CT Text

**Last updated:** Jul 2, 2026, 6:39 PM by ggarcia@calltower.com

# Overview

> [!NOTE]
> CallTower offers an eSIM product for both Microsoft (Teams Mobile) and Cisco (Webex Go). These products allow users to make and receive calls via their Teams/Webex phone numbers through the native calling experience on their mobile devices (without the need of any apps).
> 
> CallTower also offers a unique product differentiator that can integrate SMS Messages (via CT Text) with the eSIM offering. This would additionally allow users to send and receive SMS messages with their Teams/Webex phone numbers through the native messaging experience on their phone (also removing the requirement of additional branded apps (such as Teams or Webex apps).
> 
> This integration with CallTower's eSIM service means that users will be able to:
> 
> 1. Receive inbound messages in both the Tango eSIM and the YakChat service using the same number
> 2. Send outbound messages from both the Tango eSIM or the YakChat service using the same number
> 3. Move to their YakChat app for more advanced text features and the texts sent from the mobile will be available on the desktop
