You love your smartphone. You take it everywhere. But as such, it's a constant reminder of your professional life, even if you use the device for both work and play. Ideally, you will leave your smartphone at home, so you can't check it while on vacation, even if you want to. (Trust me, if you bring your phone, it WILL call out to you, even if it's buried in a hotel drawer somewhere.)

But many of us, understandably, don't feel comfortable traveling, whether it's across the country or just across the street, without a cell phone. So bring a backup cell phone if you have one--not your work phone. Or agree to only use your significant other's phone if need be.

If you absolutely have to carry your smartphone with you on vacation, it is possible to minimize your exposure to work-related applications, services and content. For example, you can deactivate e-mail accounts. You can sign out of applications that remind you of work or disable related notifications. You can hide work-related materials in "folders" or move them to screens you won't see if you need to quickly use your device. And you could simply turn off the mobile network so you can't send or receive any data, make phone calls or send texts.

Some smartphones, including BlackBerrys, even let you turn off your data services, so your smartphone can still be used to place phone calls and send text messages, even though you won't receive e-mail messages or other application updates.
