奥地利采购需求：背包

I'm a professional falconer based in Austria and I'm interested in your transmitters. Could you provide more detailed information about their capabilities specifically for falconry? It's essential for me to have real-time tracking to locate my falcon quickly in case of an emergency. Also, I would like to know how the transmitters operate—do they require a SIM card for connectivity, or is there another method? Any insights you can share would be greatly appreciated. Looking forward to your response!
