Plenty of listings with cell phone pics showing basic interiors in my market have the top 10% trophy and well-populated calendars.

However I've been told that emails are highly preferable because they can track the IP address....anyone could pick up someone's cell phone. 

Then I texted his cell phone, using the phone numbers displayed in the email Brian sent me.

Thank you @Jay Hinrichs, I actually meant to tag you a bit ago but was working from my cellphone and wouldn’t let me find you.

But we have a lot of interaction with guests before they ever arrive - we require a photo ID of whomever has booked our house (and the name and info has to match the booking info), a working cell phone number that we will send a test message to by text to confirm it belongs to the guest (or is at least in their possession), and we converse with them to let them know what to expect from us (and if we have any specific concerns we share those as well) - for example, this week if we had anyone scheduled to arrive we would be discussing the incoming hurricane. 

Because just like everything else - computers, cell phones, gasoline engines, they are becoming smaller, more powerful, and more efficient. 

My cell phone number could not be any more public!

They take marketing photos on their cell phones.

Cell phone service is still pretty bad.

Do you think that was more like an EULA on a cell phone, just some legal mumbo jumbo you had to sign through to get things done but didn't really believe was ever a "real" potential?
