Adding or switching to another eIM
You can use the Onomondo eIM to assign a different eIM to your eUICCs. You can also run your own eIM alongside ours. In order to do so:
Add the new eIM to the eUICC chips.
Confirm the new eIM can actually reach your devices.
Only once new eIM is running and validated, remove the Onomondo eIM.
⚠️ Warning: Removing the current eIM before the new one works can leave devices unmanageable.
Moving profiles to another operator
You can also download and enable another operator's profile on your eUICCs, and move your fleet's connectivity away from Onomondo. See How remote profile management works for how fleet-wide changes roll out.
