The FCC is working on legislation now (at the providers', and customers' request) to make it easier for cell companies to stop these practices. 

I am constantly making lists, notes, and plans on paper even though I have multiple cell phones, a tablet, and a laptop.

Instead of physically to your property to help troubleshoot, you could have had a quick video conference (cellphones) where you could ask your assistant to operate the door entry, while you see it on your cell phone.

Cell: 9106121646. 

You have to use your cell to call the handyman or the bank, you go out to eat with your wife or partner to discuss business strategies, you go to events and buy clothes to wear, you use your car to go to see your accountant, or the property.

Keep your cell phone in your pocket and take lots of pictures.

My current business cards that I use for networking with other investors have my name and cell phone #.

I was thinking about getting business cards, but I don't yet have a business name, LLC, website, and only have a cell phone as of right now. 

. :)Hope this response is coming through ok, I am limited to my Note 4 cell today.

I discoved an amazing thing......I started to make more money, work less and had time to go to real estate seminars, buy tapes and books and build a savings, Oh...... a supportive wife was a big help........married now this Wednesday will be 47 years.I'll be 75 years old January 16, and as I look back over the many years of Trial and Terror, I don't think I'd want to start over learning to be an investor.What I didn't have and new investors have today makes this business easier; a computer, cell phone, Internet, Bigger Pockets and lots of folks to render help and encouragement.
