Re: Looking for historical sysmoSIM-GR2 card

Hi Ralph, As I mentioned in my original solicitation, I have a friend who has sysmoSIM-GR1 and sysmoUSIM-GR1 cards, but no sysmoSIM-GR2. My friend took some pictures of his GR1 cards, i.e., Sysmocom's other historical long-discontinued cards: https://www.freecalypso.org/members/falcon/pictures/SIMs/sysmo_GR1_SIMs.jpeg As you can see from these pictures, Sysmocom's brand printing on these ancient cards is the same as on sysmoUSIM-SJS1 which they only recently discontinued: http://shop.sysmocom.de/products/sysmousim-sjs1 Given that sysmoSIM-GR2 must be newer than sysmoSIM-GR1 but older than sysmoUSIM-SJS1 (not sure about the chronological ordering between sysmoSIM-GR2 and sysmoUSIM-GR1), and given that Sysmocom's brand printing remained unchanged between sysmoSIM-GR1, sysmoUSIM-GR1 and sysmoUSIM-SJS1, I can only reason that sysmoSIM-GR2 must have the same brand printing on it - although I have no way of knowing what the background color was, as they apparently used a different color for each variant. (Their current sysmoISIM-SJA2 cards are not only unattractive black, but have different brand printing too, shifting advertising focus from Sysmocom to Osmocom and from GSM to newer G's.) It is also worth noting that as one can see in the above photo, sysmoSIM-GR1 and sysmoUSIM-GR1 cards had 8 contact pads in the IC area rather than just the required 6. I naturally have no idea if these extra C4 and C8 contacts have any functional circuits connected to them (USB-ICC or somesuch) or if they are entirely non-functional, but they are there. As I was negotiating with Grcard in China at the end of Jan into the beginning of Feb about getting a few sample pieces of their current GSM-only (no USIM or ISIM) card that can also be cut in 2FF-only form factor if the customer so desires, they sent me some pictures of those sample pieces they were going to send me, before the shipping process hit a snafu. The cards in those pictures were solid white without any markings whatsoever, but lo and behold, the IC area exhibited 8 contacts just like in those sysmoSIM-GR1 and sysmoUSIM-GR1 pictures! I can only reason that Grcard's main products these days are probably for LTE/5G in 4FF or triple-cut form factor and thus have only 6 contacts, but they still have those very old-style cards with 8 contacts in the IC area. So to summarize, I don't know exactly how sysmoSIM-GR2 cards looked, but the available evidence points to them having the following visual characteristics: * Same Sysmocom brand printing as sysmoSIM-GR1, sysmoUSIM-GR1 and sysmoUSIM-SJS1, although with an unknown background color; * 8 contacts in the IC area; * Either 2FF-only or 2FF+3FF cut (I have no way of knowing), but no 4FF cut, as the latter is incompatible with having 8 contacts. If you have a card that is still fully intact, it should be extremely easy to identify - Sysmocom's brand printing is something one can't miss, and it would certainly say sysmoSIM-GR2 on it somewhere, in the same place where other Sysmocom cards have their respective model names printed. If the card is broken out as 2FF or 3FF, it wouldn't be as obvious, but on all other historical Sysmocom cards the 2FF piece also carries the Sysmocom brand name and the model name, although naturally in much smaller print. (Looking at the picture of sysmoUSIM-GR1 my friend sent me, it looks like that one was cut for 2FF+3FF, but breaking it out as 3FF would break the printing text that spans the whole 2FF piece - perhaps sysmoSIM-GR2 was the same in this regard?) It would certainly help if Harald or someone else from Sysmocom could tell us what background color their old sysmoSIM-GR2 cards were printed in - then knowing the color would help in sifting through broken-out 2FF or 3FF cards. And yes, in the interest of full disclosure, I am seeking to re-create a product that (if successful) would probably be equivalent to the long-discontinued sysmoSIM-GR2. Or to be more precise, exactly recreating sysmoSIM-GR2 is not my specific goal (how can I recreate something I don't have, have never seen, and don't really know - obviously impossible), but *if* the cards which Grcard supposedly has available currently (stuck in shipping snafu right now) are the same platform as what sysmoSIM-GR2 used (called GrcardSIM2 in Osmocom land), then indeed the new cards I am trying to get made with pretty printing should be equivalent to sysmoSIM-GR2 - but right now there are too many unknowns.
