Device type green: supported red: not supported	Most personal consumer devices	Some personal consumer devices	M2M devices	IoT devices	(Consumer) devices with pre-loaded eSIM profile
	Phones, watches, pads, laptops etc.	Apple Watch, potentially also other devices	Automotive TCUs, metering devices, etc.	Same as M2M devices	Some routers, (some) dog trackers, etc.
Remote SIM Provisioning according to which GSMA specification?	GSMA SGP.22	GSMA SGP.22	GSMA SGP.02	GSMASGP.32	N/A
Reason for not supporting		Business rules, implemented by OEM in device, prevent to load test profiles	Device has an exclusive 1:1 relationship with a given RSP backend service. No other RSP service can interfere.		No Remote SIM Provisioning supported or disabled
Remarks			Solutions for this type of devices will more and more use the GSMA SGP.32 spec for IoT devices and not the former for M2M devices any more due to weaknesses in the old M2M spec. However, this will evolve gradually as COTS products according to the GSMA.32 IoT spec will only become available in 2025

 What are the indicators that a device is in the "consumer device" category?

• It is a smartphone, a watch, a pad or a laptop.
• Its data sheet points to the GSMA SGP.22 specification for Remote SIM Provisioning.
• Its data sheet talks about a "consumer eSIM or eUICC".
• It allows to scan a QR code with a camera to load the eSIM profile.

What are the indicators that a device is in the "M2M device" category?

• It does not allow to scan a QR code or to enter an activation code text string to download an eSIM profile.
• Its data sheet points to the GSMA SGP.02 specification for Remote SIM Provisioning.
• It is a small scale and/or embedded device.
• It serves typical M2M use cases (metering, remote control of devices, ...).
• The device was launched 2024 or earlier (but also some later devices will be in this category).

What are the indicators that a device is in the "IoT" device category?

• It is a device which was launched 2025 or later.
• its data sheet points to the GSMA SGP.32 specification for Remote SIM Provisioning.
• it is a small scale and/or embedded device (same as M2M).
• it serves typical M2M use cases (metering, remote control of devices, ...) (same as M2M).

 

Besides beeing in one of the device categories, which can be supported, your device must not have special test certificates in its eSIM according to GSMA SGP.26. It is very unlikely that you have such a device if you did not explicitely sourced it with this feature (such devices cannot be purchased on the open market).

What Profiles are available?

Out-of-the-box, we provide profile packages with profiles according to the following types:

• GSMA TS.48 – all different flavors
• Rohde&Schwarz GSMA Test Profile (availability requires approval from Rohde & Schwarz)
• Anritsu RTD LTE Profile and RTD 5G Profile (availability requires approval from Anritsu)

 

Which of the multiple GSMA TS.48 test profile types should I use?

The profiles differ in the SAIP version (v2.1 versus v2.3) and whether they use BERTLV. If you do not know what the eUICC in your mobile device supports, we recommend using the simplest profile to prevent interoperability issues, i.e. SAIP v2.1 and NoBERTLV.

 

What if I have purchased a profile package for a specific profile type but then need another profile type

You need to purchase another package with the other profile type.

 

What settings do the profiles have?

• For the GSMA TS.48 eSIM test profiles you can check all details on GSMA’s Github: https://github.com/GSMATerminals/Generic-eUICC-Test-Profile-for-Device-Testing-Public
• R&S GSMA eSIM Test Profile: This is equivalent to the R&S test SIM card. For details, please contact R&S.
• Anritsu LTE and 5G eSIM Test Profile: These are equivalent to the respective Anritsu LTE and 5G test SIM cards. For details, please contact Anritsu.

 

I need a profile with settings which differ from the settings of out-of-the-box available profiles. What options do exist?

Test profiles which belong to an existing profile package reside al the Remote SIM Provisioning Server (SM-DP+) and cannot be changed on this server anymore. There are two options:

• You modify the profile yourself after it has been downloaded to the device. There are two options for this:
  • Via AT+CSIM commands managed by a tool like the COMPRION iSIMConnect (https://www.comprion.com/products-solutions/products-solutions-a-z/isimconnect/). But be aware: not all devices support this or have this enabled.
  • Via Remote File/Application Management. This requires connecting to the device via a Network Simulator and an OTA Server like COMPRION’s eUICC Profile Manager – Explorer(https://www.comprion.com/products-solutions/products-solutions-a-z/euicc-profile-manager/).
• COMPRION provisions a dedicated profile package for you with an eSIM test profile template according to your requirements. For some requirements this is not too difficult (e.g. changing MCC/MNC), for others it might be more complex. Please contact COMPRION with your specific requirements if you want to discuss this option.

Does the mobile device need to be connected to the Internet for an eSIM test profile download?

Yes, this is essential as the profile is downloaded from a cloud-based Remote SIM Provisioning service.

 

Do the profiles of my profile package, which I can download via the provided QR code, differ from download to download?

With one exception they are all identical. Each profile needs to have a unique ICCID. But this should not be relevant for you.

 

How do I download an eSIM test profile to a device?

Different devices require different activities:

• Consumer devices: The eSIM profile download is initiated in the user interface of the device. For details, please check the OEM’s documentation of the device.
• Consumer smartwatches: typically, the profile download is managed via a complementary smartphone. For details, please check the OEM’s documentation of the device.
• IoT devices: There are two options:
  • The profile download can be triggered via the “eIM” service if the device is associated with such a service.
  • It may be possible to trigger the profile download also on the device. If this is possible the detailed methodology will strongly depend on the device. For details, please check the OEM’s documentation of the device.

 

I cannot load the profile to a device. What is wrong?

There are multiple possible reasons. Most frequent reasons are:

• Device type is not supported. See above.
• Device has a test eUICC, i.e. an eUICC with certificates according to GSMA SGP.26. If you have purchased the device through “normal” channels, this will not be the problem.
• Mobile device has a carrier SIM lock. The device will only accept eSIM profiles with certain carrier-specific configurations, but not normal test profiles. In this case, COMPRION might be able to help you to work around this problem. Please contact COMPRION to discuss.
• Device has certain OEM/MNO business rules configured which prevent normal eSIM test profiles. This is often the case for smartwatches. Not for all, but in particular it holds true for Apple Watch.
• Mobile device need a special Remote SIM Provisioning mechanism for the profile download. This is often the case for smartwatches. Not for all, but in particular it holds true for Apple Watch.
• eUICC of the device is not interoperable with eSIM profile. Although standardized, this happens from time to time. An indication that this is the problem is that the profile can be downloaded, but not installed / activated. Instead, the eSIM returns an error to the eSIM Test Profile Service backed (SM-DP+)

 

What to do if a device has a carrier SIM lock?

COMPRION might be able to provide a customized eSIM test profile which shows the required carrier-specific settings. Please contact COMPRION to discuss.

What is eSIM “activation”?

This term is not part of the GSMA eSIM specification. It is used by different devices in different ways. Most often, it refers to the phase after the profile has been downloaded, installed and enabled. Then the phone starts to try connecting to a mobile network which fits the configuration of the eSIM profile. Depending on the device, it may give up after some 10 seconds or only much later (some devices try for 12 or 24 hours). You may not be able to terminate or interrupt this process. E.g. disabling and deletion of the profile might only be possible when the device has finished the activation procedure.

 

The eSIM test profile is downloaded, installed and enabled on the device, but the device does not connect to my network simulator. Why?

Most likely, the configuration of the network simulator does not match with the configuration of the eSIM profile. Please compare the profile settings with the settings of your network simulator. Please check in particular: MCC/MNC, IMSI, Authentication Algorithm.

 

The eSIM test profile is downloaded, installed and enabled on the device and the device is connected to a Network Simulator, but the device does not show the expected behavior. Why?

There are multiple potential reasons dor this:

• The eSIM test profile does not configure what you intent to test. Please check the eSIM profile documentation to check if this is the case
• The Network Simuator is not configured accordingly
• The device has been customized by a MNO (can be if you purchased the device not on the open market but via a MNO channel). In this case, the behavior of such devices in a network may depend on MNO-specific configurations in the eSIM profile, which a MNO-own profile may contain but not a generic test profile. In particular if you have seen a different behavior of this device with a MNO operational profile in the live network of this MNO compared to what you see with a test profile and a network simulator - then this might be the reason.

 

How can I delete an eSIM test profile on a mobile device?

For consumer devices, this can only be done by the user on the device itself. Please check the OEM’s documentation of the device for this. The GSMA specification for eSIM prevents mechanisms from deleting a profile from remote.

Please note: There is a difference between “disabling” a profile and “deleting” a profile.

Typically, the process to delete a profile needs internet connectivity of the device (WLAN), as the GSMA eSIM specification requires the device to send a notification of the deletion back to the Remote SIM Provisioning service. If this message cannot be sent due to lack of internet connectivity, the deletion process may not be finished. If the device becomes connected later on, the device will automatically try to send the message later. But this may not happen immediately. It may take hours before the device does this.

 

Do I have to delete a test profile on the device after testing?

If you are using the COMPRION eSIM Test Profile Service Packages, you do not need to do this. But you may want to do this to clean up the device.

I lost the QR code of my profile package. How can I get it again?

Please contact COMPRION.

 

How do I get to know how many downloads are left from the package of downloads which I purchased?

COMPRION provides a dedicated website where you can access this data. If you have not received the link, get in touch.

 

The QR code of my profile package became disclosed to people who should not use my profile package. How to mitigate?

Unfortunately, there is no way to mitigate.
