This article explains how eSIMs work within Aircall, including how calls and SMS are handled, how data works, and what to expect from the Aircall Mobile App when an eSIM is active.

Making outbound calls

When your eSIM is active, you can make outbound calls from any of the following:

  • Your mobile device, using the native phone dialer
  • Agent Workspace, desktop or web
  • A CTI integration
  • The Aircall Mobile App

Regardless of which device or interface you use, the person you call will see your Aircall number as the caller ID.

Note: When making a call from the Aircall Mobile App with an eSIM number selected as your caller ID, you will be prompted to choose how to place the call: through the native dialer (via eSIM) or through the app (via VoIP). This prompt appears each time you initiate an outbound call from the mobile app.

Receiving inbound calls

When someone calls your Aircall number, it will ring on:

  • Your mobile device, via the native phone app
  • Agent Workspace, desktop or web
  • A CTI integration
Important: Incoming calls to your eSIM number will not ring in the Aircall Mobile App. Your device's native phone app handles inbound calls instead. You can still use the Mobile App to make calls and access other Aircall features.

All answered calls are logged in your Aircall account regardless of which device you use.

If you miss a call, the missed call notification will appear on both your native device and in the Aircall Mobile App.

Availability status and eSIM calls

Your Aircall availability status applies to calls received through Agent Workspace and CTI. Calls routed to your eSIM via the native dialer are not affected by your availability status in Aircall: they will ring on your device regardless of whether you are set to available or unavailable in the platform.

Note: On certain analytics dashboards, you may see inbound calls and outbound calls on users that the previous status was unavailable (they may change from Unavailable to in a Call to unavailable)

Sending and receiving SMS

You can send SMS from:

  • Your mobile device's native messaging app
  • Agent Workspace or a CTI integration

All messages sync with your Aircall account.

Note: Messages sent from Agent Workspace or a CTI integration will not appear in your device's native messaging app. You can view these messages in the Aircall Mobile App.

Using mobile data with your eSIM

If you selected a 20 GB or 50 GB data package, your eSIM provides mobile data directly. You can browse, use apps, and access the internet using this allowance.

If you selected the 0 GB, voice and SMS only package, your eSIM does not provide internet access. To connect to the internet, use Wi-Fi or, if your device supports dual SIM, the data from a second SIM card.

eSIMs and direct numbers

eSIMs can only be used with direct numbers. A direct number means:

  • The number is assigned to one specific user
  • The number cannot route calls to a team
  • The number can redirect to other individual numbers, but not to teams

If a French mobile number is currently configured as a shared line, it must be converted to a direct number before an eSIM can be assigned. See direct numbers configuration for more information.
