Harald, please, I'm not asking you to fix this for me, just to point me in the right direction, in my efforts. Which you did.
Investigation with supplier and vendor is already undergoing, and I'll let you know, if I obtain any kind of info, that might be interesting and/or useful for the community. I also have sysmocom SJS1 on the way, so it will shortly stop being pain for me, and I'll have time to invest in reverse-engineering the chinese green cards. Also if I'll have the documentation available, I'll contribute with patch to use with GR-USIM cards. And I disagree that solving or trying to solve the question, whether these chinese sim cards are easy-to-use and programmable, will not do any good. It might not be the most important or interesting topic, but still it is something, and something useful in the end. But as I said in the beginning, please, I'm not asking you to spend much time on my issue. Initial motivation was my idea, that I cannot search or that this should be issue, somebody in this community already tackled, it's not, and I take that as conclusion. Take care Harald, and no hard feelings, really Best Regards Marek Sebera On 01/31/2018 03:12 PM, Harald Welte wrote: > On Wed, Jan 31, 2018 at 02:49:34PM +0100, Marek Sebera wrote: >> Could you maybe tell me, because I haven't found anywhere in docs, which >> software and its version did you traced? > > This was some 5 or more years ago.
