@tnt thanks, but we have stopped selling rtl-sdr after the early days when they were still new and not easy to procure outside of direct mail-order from China.

@f4grx @osmocom must have been 2006 or 2007, as that was when openmoko was releasing Neo1973 and GTA02. And definitely IMS is way more complicated than even the best intern can do on 3 months...

We're happy to announce the availability of yet another FPC adapter cable for the MFF2 solder-type SIM / eUICC form-factor. This is useful in R&D and testing of IoT devices. https://shop.sysmocom.de/MFF2-footprint-in-circuit-solder-FPC-cable/MFF2-in-circ-fpc #sim #euicc #esim #gsm #oshw
