Off to Oregon I went for 20 days with spotty cell service with much anticipation of closing on the new property when I returned. 

Get a local cell number (you'd be surprised what a big deal this is to some people!).

He gave me advise on preventative maintenance, a couple of tips he had learned along the way, and gave me his cell phone number and said to give him a call if I ever had a question or needed advise on a rental matter.   

I'm curious what the pricing model is like for smaller rentals since they need to deploy a cell router at the property.

We had LLC's & yet she tracked us down by my name & our cell phone #'s.

Utility collections go hand-in-hand with that, if they don't pay their lights/gas, their home expense isn't top priority (over say, a cell phone payment or cable), so you can expect rent won't be top priority above all else.I rent mostly in low-c areas to immigrant populations, so my tenants don't always have social security numbers and credit scores.

New tenant moved in Sept 1st into back lower unit.A friend on behalf of him is using his cell via text to contact me.

All the cell service is down.

he even told me tge kind of sickness its cancer 

In my experience, it is an excellent tool for tracking incoming calls and being able to match the marketing that generated that call (i.e. a different number for different mailings, etc.) but I always found it to be cumbersome to make outgoing calls from, considering a cell phone is pretty simple to use.
