Workflow | eSIM setup and implementation

Prerequisites

  • eSIM-capable devices and their specifications.

  • The eSIM has an active cellular connection. The eSIM must be connected using its bootstrap profile or another active eSIM profile before you can download, enable, or delete eSIM profiles from Digi Remote Manager.

  • A carrier account with one or more cellular carriers.

  • A download-ready eSIM profile provisioned by each carrier/MVNO.

  • eSIM cards inserted in every device, if the eSIM chip isn't already embedded.

  • Digi 360 or Digi Lifecycle Assurance license for each device.

  • Individual with administrator access to Digi Remote Manager.

  • Devices registered and connected to Digi Remote Manager.

  • DAL OS firmware version 25.11 or newer and 26.2.147.55 for devices that have a built-in eSIM.

Workflow

Action

Considerations

Confirm that your Digi device (EX, IX, TX series) or Connect IT 4 and its cellular modem module supports eSIM functionality.

  • Not all Digi router models or modem SKUs support eSIM; hardware differences matter.

  • Some carriers may support eSIM only on certain cellular modem modules.

  • Ensure your deployment location (country/region) allows eSIM activation on your chosen carrier.

Update the devices to DAL OS 25.11 or newer and LTS 26.0 for devices that have a built-in eSIM.

Action

Considerations

Choose a mobile network operator (MNO) or MVNO that supports eSIM.

  • Carrier coverage and signal quality vary by deployment area.

  • Some carriers require special IoT eSIM profiles or enterprise accounts.

  • Check whether the carrier uses SM-DP+ servers compliant with GSMA standards.

Identify the data plan, APN, and activation method required by the carrier.

Action

Considerations

Request activation codes from your carrier.

  • Different carriers have different activation processes (QR code, code string, LPA APIs).

  • Store these activation details securely—they are equivalent to SIM credentials.

  • If activating at scale, ensure the carrier can bulk-issue activation data.

  • To add these codes to Digi Remote Manager you need to use a CSV file.

Confirm whether your carrier delivers profiles via QR code, manual code entry, or API-based provisioning.

Action

Considerations

Apply the carrier’s APN settings either manually or through DRM.

  • APN misconfiguration is a common cause of failed data sessions.

  • Some carriers use private or IoT-specific APNs that require credentials.

  • Ensure fallback APNs are disabled unless intentionally used.

  • See your DAL OS-specific user guide, Configure cellular modem APNs.

Confirm that the router is using the correct SIM slot/profile.

Action

Considerations

Add the devices to Digi Remote Manager and confirm they are online.

  • Digi Remote Manager provides centralized eSIM management; without it, you cannot use this functionality.

  • Ensure your users or administrators have the correct administrator permissions.

  • Use a template if you plan a large-scale rollout.

Add the activation codes from the carrier(s) to Digi Remote Manager.

Add an activation code to a device.

Action

Considerations

(Optional) Configure a preferred eSIM profile.

Configure SureLink for eSIM.

See your DAL OS-specific user guide, Configure SureLink active recovery to detect failures.

Action

Considerations

Verify the device connects to the network using the newly activated eSIM.

  • Check the SIM Management card on the device dashboard to verify that it is using the eSIM.

  • Test different locations or antennas if the signal is weak.

  • Verify that roaming and LTE/5G bands are permitted for your region.

  • Confirm firewall rules or VPN settings do not block outbound connectivity.

 

Check IP address assignment, signal strength, and registration status (LTE/5G).

Action

Considerations

Enable SIM/eSIM status monitoring in Digi Remote Manager.

  • Monitoring prevents downtime by signaling when a profile becomes inactive.

  • Use the dashboards to track data usage and performance of your fleet and individual devices.

  • Establish security policies for eSIM profile changes or reassignments.

Configure alerts for signal loss, SIM failure, or profile issues.
