Hey guys! I have an important question for you. I have recently come back to my usual working regime. Now I work from the office again. I also have lots of business trips. So, I leave a house for a while. I'd like to install some special system that will help me to control my place. But the issue is that I need that system to be not connected to wi-fi. When I am out I usually turn off my Internet router. So, there is no signal. I've heard that the Ajax systems work with a sim card, don't they?
