Failing SuperSIM (fakemagicsim) cards?

Has anyone experienced these cards (as can be found on eBay) failing after a matter of months? I have some I programmed ~1 year ago and which worked fine in a bunch of Calypso handsets with NITB, but now I get "SIM card absent" whenever I try to make a call (but LUR is accepted OK and can see programmed IMSI in NITB debug). An operator SIM and an R&S test SIM is working fine with the setup. Also tried reprogramming the SuperSIM card (command used below).
