Re: Bringing back GrcardSIM2

Hi Harald, Thank you for the encouragement. I just found a copy of GRSIMWrite version 3.10 on the Internet (to those whom I emailed off-list asking for a copy, that request can now be scratched :), so I will try running it on that WinXP machine. Hmm, such visual observation seems to be only possible with a phone handset whose fw includes a Chinese font (how can a device display something in Chinese if it has no font for it), and AFAIK none of the Western-market classic GSM dumbphones I play with support Chinese characters. It looks like I will need to invest in a SIMtrace setup (hardware + learning curve) in order to truly confirm for sure what these cards do and don't do in terms of STK. Adding to my long to-do list. Now the big question in need of answering - just *why* am I messing with these Grcard SIMs instead of embracing the latest offerings from Sysmocom like the rest of this community? Two reasons: 1) As a general principle, I feel severe displeasure whenever something (anything really) that was available in the recent past gets discontinued and taken away. It is a well-known trait in human psychology, called loss aversion. Thus I see good moral value in bringing a discontinued product back from the grave just for its own sake, regardless of how poor that product may actually be. 2) Cost: this Grcard deal seems to be the only way to get programmable SIM cards in 2FF-only cut with a GSM-only file system (no USIM/ISIM) at an affordable price (a few hundred USD for 100 to 200 cards), without spending 3-4 kUSD on an MOQ-based custom order from The Premier Vendor. Spending 3-4 kUSD just on the SIM cards alone, on top of all other costs like BTS hardware and everything else, is simply not justifiable unless there is absolutely no other way. So I am trudging along... M~
