Are jmp.chat eSIM adapters unique

Jmp.chat provides an adapter (a eUICC device?) that can be used to store an eSIM on a physical card. I have such an adapter that I have already used for a plan tied to my identity. Is it safe to purge the chip, and then to reuse it for anonymous communications?

I think the eID should be unique and gets transmitted.

That’s probably the ID that forbids me from installing (another) speedtest eSIM, though “ID” could also refer to IMEI perhaps. I’d have to try another phone.

Error code: ES10B_ERROR_REASON_UNDEFINED

Last HTTP response (from server):

{
	"header": {
		"functionExecutionStatus": {
			"status": "Failed",
			"statusCodeData": {
				"subjectCode": "8.2.6",
				"reasonCode": "3.8",
				"subjectIdentifier": "Matching ID",
				"message": "Refused"
			}
		}
	},
	"transactionId": "[You don't need this]"
}

Last APDU response (from SIM) is successful

Based on this, it is a part of the transmitted information, if I understand it right: www.sharetechnote.com/…/Handbook_LTE_eSIM.html

If you want to keep identities independent: don’t mix the esim adapter, just to be safe

Also

  • don’t use the same phone
  • don’t use the same location when on the network
