If it is a cell number, try a text and call.Not excusing the lack of responsiveness, but part of the problem is this information is very urgent for you, but not a high priority for the previous landlord.

In essence, he blames me personally for depriving him of quiet enjoyment of his property and forcing him to sleep in the kitchen with fans and air filtration devices on full blast so that he can block out the noise.He previously asked me to furnish my tenant’s personal data so he could investigate and possibly sue her, which I declined to do.

Once the rent is deposited, I then transfer the funds to my personal account from my mobile device; works really well for me.

I know, I was a cell biology grad student.

We do not have such a thing since we use our cell phones for personal and landlord purposes. 

I need to streamline my device so that I don't have to waste more of my time.  

Included in my monthly fee is the cell phone service for the wireless connectivity fee (so no one has to go to the property to read meters).  

We are presently working on a deal with a larger apartment complex and, if we get it, will push our ISP for far better pricing in exchange for an exclusive arrangement for 3 - 5 years.At a few smaller properties we use the router supplied by the ISP, but at our student rooming house and in our multiunit buildings, their gear is insufficient and we tend to use our own routers, switches and wireless access points (we do not use repeaters as they extend range at the sacrifice of performance: fine in your own house, not helpful when you have 20 - 50 devices on the network).  

Everyone has a cell phone now, so unless it's required by law, I'd just put in cable and I bet no tenants would complain about that.

I can't negotiate with the cell phone co.
