FAQs

Do devices require a Digi Remote Manager license to use eSIM?

Yes. A Digi RM license is required for devices using eSIM. Basic cellular connectivity does not require Digi Remote Manager, but any eSIM-related workflows do.

Are eSIM provisioning or erase actions logged in Digi Remote Manager?

Yes. All eSIM-related actions performed within Digi Remote Manager are recorded in the Audit Log for traceability, including provisioning, activation, and erase operations.

How do I obtain bulk activation codes for devices?

Contact your carrier representative to request bulk activation codes.

What is an eSIM?

About eSIM technology

eSIM technology is a method that uses a programmable eUICC chip to store and manage digital cellular subscriber information. This programmable chip - eUICC chip - is a small, secure chip that can store and update digital credentials used to identify the device on cellular networks . This chip supports downloading, activating, and switching between mobile carrier profiles through software rather than relying on fixed, pre-programmed information. This combination enables the management of cellular connectivity through software instead of swapping physical SIM cards in and out of devices. This gives you more flexibility and control over how your Digi eSIM-capable devices connect to mobile networks, as well as the cellular plans you choose.

In Digi Remote Manager, monitor eSIM status by checking whether the device has successfully obtained a carrier profile (for example, activation codes showing Available, Downloaded, or Failed) and whether the device is currently registered and passing data on the cellular network using the intended profile. This helps confirm both successful provisioning and ongoing connectivity.

What eSIM allows you to do

  • Activate cellular service remotely — no physical SIM swap needed

  • Switch carriers or plans digitally

  • Enable secure provisioning for IoT devices, routers, and industrial equipment

  • Reduce logistics costs (no SIM card shipping, no mechanical SIM tray)

Why eSIM is useful in IoT and Digi devices

  • Simplifies deployment of large fleets (remote provisioning)

  • Reduces failure points (no SIM tray damage)

  • Improves security through standardized provisioning flows

  • Supports global deployments without handling multiple SIM card types

In simple terms

Digi eSIM technology enables carrier switching and provisioning without physical SIM changes so you have greater flexibility, control, and security in managing your wide-area networks.

About eSIM technology
../About.htm
Does my device support eSIM?

Digi has many eSIM-capable devices, as well as some devices that do not support this technology.

Can I apply an eSIM purchase to a previously registered device?

No. This capability is not in scope for the eSIM accessory launch.

Can I order the eSIM on its own?

No. The Digi eSIM card accessory must be ordered with an equal number of eSIM capable devices.

How long does it take to load an eSIM profile onto a device?

No specific duration is provided, but typical provisioning times are comparable to standard carrier eSIM activation workflows.

How many profiles can I load onto an eSIM?

A maximum of 7 profiles can be loaded in addition to the pre-loaded bootstrap profile.

What outbound firewall rules are required to activate and use eSIM?

Outbound rules are required only for customers using a private APN or private network configuration. Otherwise, no special firewall configuration is required. For a list of outbound firewall rules required for eSIM management on a private network, please refer to the Default outbound WAN/WWAN ports topic in the Digi Remote Manager user guide.

What is the difference between eSIM and multi-IMSI?

Comparison between eSIM and Multi-IMSI

Although both eSIM and multi-IMSI are used in cellular connectivity, they solve different problems and work in different ways.

Synopsis: Digi eSIM provides you with the ability to use native profiles, is not locked to a particular carrier, and can load multi-IMSI profiles from MVNOs!

eSIM technology

Multi-IMSI technology

What are they?

eSIM is a technology that allows a device to store multiple digital carrier profiles on a programmable chip.

These profiles can be:

  • Downloaded remotely

  • Switched through software

  • Replaced without handling a physical SIM card

Key idea: A device can load and manage different carrier profiles on the same chip.

Multi-IMSI is a technology where a single SIM card (physical or eSIM) contains multiple IMSIs—multiple subscriber identities—programmed into it. The SIM can switch between these identities based on rules such as:

  • Network availability

  • Roaming conditions

  • Carrier agreements

  • Cost or coverage

Key idea: A single SIM can act like it belongs to multiple carriers or plans.

How do they differ?

eSIM = digital SIM with downloadable carrier profiles

  • Profiles can be added, removed, and updated remotely.

  • Works through a remote provisioning system.

  • The device can store several profiles and choose one at a time.

  • Focus is on flexibility and eliminating physical SIM swaps.

Multi-IMSI = single SIM with many identities already built in

  • IMSIs are preloaded by the SIM provider.

  • The SIM switches identities automatically based on rules.

  • No need to download or install separate profiles.

  • Focus is on global coverage and automatically avoiding roaming issues.

What is a simple description of each one?

eSIM is like having a device that can download different SIM cards as needed.

 Multi-IMSI is like having several SIM cards built into one, and the card switches between them automatically.

Why use eSIM and not multi-IMSI?

eSIM provides native profiles, is not locked to a particular carrier, and can load multi-IMSI profiles from MVNOs!
