GPRS/GSM shield

Hi All,

Has anyone any experience with this company YANTRR http://yantrr.co/index.php?route=common/home
I am looking to buy a GPRS/GSM shield for the Beaglebone black for a weather project.

Any information would be appreciated.

I used 4g modem usb based. (via pcie typed usb) or normal usb b4. works fine.
