Let's make our own Turbo sim, any ideas?
So all those proxy cards cost a lot of money, but why not to make your own. Schematics are rather easy and the most expensive part of those cards is microcontroller ( MCU).
I made some research on the internet and found out that Turbo sim uses atmega128 MCU, but does anyone has any idea what MCU uses Stealthsim, Next sim and so on. I think that MCU's on those cards are the same. And it is very likely that required MCU's cost few bucks in China. So all you need is to develop a PCB and place MCU on it.
Even if it would be only an experiment version, but why not to try out?
Another idea is that those cards might be manufactured by one factory, so if we know the MCU specification it would be possible to track manufacture and order directly from it.
Another thought is that Magic Sim and all of those mentioned above use the same MCU.
And of course the hardest part is the software, but we have Turbo sim software, right?
Let's throw some ideas and make things cheaper=)
