GSM modem

Hi

we like to integrate a GSM modem, the modems on the supported list aren't easy to find thies days. Have you tested one of thies:

-Multitech Systems mtcba-g-f4-ed-eu Cable/Radio Modem

-Telit GT 863-PY

-Falcom SAMBA 75
GSM Modem USB Stick

Or do you have other tested gsm modems tjat we can find.

Thanks
