If you have an iphone you can download a free app called "talkatone" gives you a free number.

They are not cheap and obviously require some kind of cellular plan, but I was able to get them to work using Mint mobile (you need a phone to activate the sim card on first, like an old iphone) Ive had 3 of these up watching a property in Cleveland, OH for well over a year, and Ive only had one issue where I needed to go check on the camera itself, (the plug for the solar panel came disconnected and just needed plugged back in) This camera in particular is nice because its actually 2 lenses that capture the full 180 degrees, so one cellular plan for "2" cameras.

If my kitty was fat enough, I'd take 5% any day and throw my laptop and iPhone in the trash, sleep till 10am and play guitar with my amigo's haha

@Edward Lui management is free I use my iPhone.

If you have an iPhone, there is a way to make your own "Contact Card" in the Contacts app: I normally add my cell, email, and company there; list your "Company" as "Investor".

I am not able to add it to ibooks on my iphone

If you are listing it yourself with iPhone photos, that's not the best way.

It was long before iPhones were avilable so it was a long boring wait.

Willing to pay for functionality that let's me do this on my iPhone quickly and easily.  

For example, all I have to do is type “rental1” in my iPhone and it will replace it with that first reply.
