I get within inches of him with my cell light and he doesn't move.

They can use a cell phone and sort of use a computer, but that's about it. 

@Chris De Celle here are some photos

I have an exisiting cell tower rooftop easement agreement with a wireless cell agent that sub-leases the space to Verizon. 

sorry, didn't have cell coverage for a few days and just catching up. 

I need someone with a strong background, influence and knowledgeable about cell tower contracts. 

Curious what the BP community thinks of having smart devices like this in higher end STR or long-term rentals?  

Use Experian Boost from the Experian credit report site to use things like your cell phone bill being paid on time each month to improve your credit and your rent being paid on time.

but is there any chance to find skip tracing services that give me only 1 best phone number to each owner and with high accuracy.No, people change numbers, especially in this day of cell phones.

So the agents these days are Taught to put this one their cell phone  " Thank you for calling for faster service please text me "  well that ends it for me :)  the few times i try to engage in a text conversation I just get way to frustrated its too slow. theres no personal inflection I want to talk to agents to feel out If I think there is a light bulb on or if they are suitable for my needs I can do that quite quickly on the phone.So to answer the OP  I am not sure what you do to get anyones attention these days in the go go text dont talk modern world.
