Good performance but does not stack
I have had good performance with this shield. Using hologram sim card everything has worked without issue. The only problem is that if you attempt to stack it on your arduino with stacking headers it doesn't fit because the sim card holder on the underside of the shield bumps against the USB port on the Arduino uno.
