We have put together this step-by-step guide for testing your hardware and 1oT eSIM. To make sure that your larger deployments with 1oT eSIM will be smooth and successful.

Follow along with one eSIM to make sure that everything from the hardware and Terminal side is set correctly. Once all the steps are completed, you are ready to start using the 1oT eSIM.

If you happen to have problems during the testing or something is unclear, don't hesitate to contact us.

Let’s get started.

Before you activate your 1oT eSIM in Terminal, please keep in mind the following:

  • If your device has an old SIM card, don’t throw it away before you've completed all activation steps for your new 1oT eSIM card.

  • Make sure that your device supports the following features:

    • At least one of the network access technologies: 2G, 3G, 4G

    • SMS-PP MO (outbound SMS), SMS-PP MT (inbound SMS) and BIP/CAT-TP

    • SIMToolkit commands

    • AT commands

For hardware compatibility, please consult with your hardware manufacturer or check the 1oT eSIM supported hardware list and 1oT eSIM test reports.

Step 1: Find the EID number of your 1oT eSIM

There are 2 variants of the 1oT eSIM card. Please follow the guide on how to find an EID number depending on which one you have ordered from us.


Option 1 - Plastic eSIM:

  • The plastic eSIM consists of 3 plugin sizes — standard, micro, and nano. Determine which size fits your device.

  • Use your thumb to detach the correct eSIM card plugin along its outside perforated lines. Be careful to keep the card whole. For example, you'll only pop out the nano eSIM card if you need the nano eSIM for your device.

  • The plastic card has the EID number marked on the card.

  • Insert the eSIM card into your device's SIM slot.

Option 2 - Embedded eSIM:

  • The Embedded eSIM is in the MFF2 format.

  • MFF2 eSIM is then soldered onto your device, and you will not be able to remove it.

  • The MFF2 has the last digits of the EID number marked on the chip.

Once you have been able to find your EID number, please mark it down. Continue to the next section of testing if your eSIM card is attached to the device.

Step 2: Activating your 1oT eSIM on 1oT Terminal

  • Login to 1oT Terminal.

  • Go to the "SIMs" view and locate your eSIM by searching for the EID number.

  • If the eSIM is still in Shipping mode, switch it to Live.

Congratulations your 1oT eSIM is now live and active. 1oT eSIM comes with a Default Carrier profile, which will allow network connectivity globally.

Step 3: Setting up your device

Start the following steps with your device powered off.

  • Turn on your eSIM compatible cellular device.

    Note!
    Not all cellular devices support eSIM. You can check compatibility with your device manufacturer or check the 1oT eSIM supported hardware list
  • Depending on the device, you might need to enable BIP or STK function on your device.

    Please refer to the device specification/manual or check 1oT eSIM test reports
  • Set "terminal" as the APN on the device.

  • Check for network attachment.

    The first time the eSIM is used, this might take up to 1 minute.
  • Verify ICCID or MSISDN on your device and confirm these values match with the information displayed in 1oT Terminal's eSIM Management Tool.  You can access the eSIM Management Tool from the menu bar.


The ICCID you see attached to an EID is the default carrier profile that’s active on the 1oT eSIM card.

Make sure you can establish a data session and have Internet connectivity.

Step 4: Switching Profiles on 1oT eSIM

The following section describes a quick and basic test for making sure that the 1oT eSIM profile's management works as expected.

This test consists of three steps involving:

  • Download profile
  • Enable profile
  • Delete profile

Keep your device powered on and connected to the network during the process.

Download a new profile:

  • From the 1oT Terminal eSIM Management Tool, select the desired Carrier.
  • Go through the steps to choose a data package, and finally select your test eSIM based on the EID. Then select Confirm Download transaction.
  • The download process can take up to 5 minutes.
  • Terminal will notify you of a successful profile download, and the new profile will be available under your eSIM view.
  • Note! If Terminal notifies you that the download has failed, please proceed to troubleshoot eSIM compatibility on your device.

At this stage, you are still connected with the default carrier profile.


Continue with the next steps to enable the new profile.

Enable operation:

  • From 1oT Terminal eSIM Management Tool, select one of the downloaded eSIM profiles (ICCID numbers) and choose Enable option.
  • This process might take up to 5 minutes.
  • During the process, your device will detach from the network and re-attach again.
  • Terminal will notify you of a successful profile enable, and the new profile will be active on your 1oT eSIM.
  • Note! If Terminal notifies you that the enable has failed, please proceed to troubleshoot eSIM compatibility on your device.
  • Once connected with the new profile, please verify the ICCID or MSISDN on your device and confirm these values match with the information displayed in the 1oT Terminal view.
  • Make sure the new profile is registered on the network, and you can establish a data session.

Delete operation:

  • You will not be able to delete an active or default carrier profile.
  • Please switch back to the default carrier profile to test the Delete operation. Use the same Enable Operation steps you just did when you swapped to the new profile
  • In 1oT Terminal’s SIMs view, select the same eSIM as in the previous step and choose the Delete option for the profile you wish to delete.

Terminal will notify you of a successful profile deletion, and the deleted profile will disappear from your eSIM view.

Note! If Terminal notifies you that the delete has failed, please proceed to troubleshoot eSIM compatibility on your device.

Time to celebrate!

Once all three transactions are successfully tested and confirmed, you can be assured that your device and 1oT eSIMs are fully functional and compatible with remote SIM provisioning.

Troubleshooting help

The most common cause of remote provisioning issues is non-compatible devices.
Please make sure your device supports and you have enabled STK and BIP functionality.

You can check compatibility with your device manufacturer or check the 1oT eSIM supported hardware list. Please refer to the device specification/manual or check 1oT eSIM test reports for any configuration help.
