Hello @canadian.ric
I will not be commenting on legal stuff you mentioned though of course I accept its validity. You may try checking with some customers organization in that regard.
Your nick refers to Canada, so let me double check whether you have purchased a FP directly from the company? If not, the reseller would be your first contact.
And now to troubleshooting. Either the device or the card is faulty. If the device is faulty, I would imagine changing the top module might help. Is there any FP5 in your vicinity that you could try that? Or a FP Angel?
If the card is faulty (yes I remember you checked several of them, and also mentioned troubleshooting - have you run an internal test as suggested at the website?), then you may consider asking your provider for a new replacement or switching to eSIM
My experience as a anecdotal reference. I renewed my old SIM card prior to the purchase of a FP5 following the official guidance (the card is to be newer than 2 years) and after reading some salty experience stories on the forum. Have not had any issues so far but the card is slowly reaching its limit. I have tried several (four I believe?) eSIMs and all worked.
What I would do? Apart from nagging CS about the issue, I would (1) renew my SIM card, (2) run the internal tests, and if (2) it turned faulty → (3) purchase a top module out of my pocket and claim the reimbursement from the CS (accepting it might come late or be disputed), (4) consider getting an eSIM as a backup
