On Arrival

When you arrive at your destination, and the flight attendant says it's safe to reactivate all electronic devices, you'll finally be able to turn your phone on again. If you are traveling domestically, you'll want to make sure your phone can find your home network or at least a network with which your carrier has a roaming agreement. If you're traveling internationally, you'll want to make sure you're able to connect to the network and make phone calls. You might have to switch frequency bands on your cell phone when you arrivefor example, switching from 1900 GSM in North America to 900/1800 GSM in Europe, Asia, or Africa.
