Borrow a new phone. Certain cell phone carriers, such as Sprint and Verizon, do not use a global service network like the type used in many countries, according to the New York Times. The cell phone provider may allow you to borrow a global phone for free or at a low rate for use while traveling. You can then set up an international call plan with the service provider.
Sign up for a global data plan. Data plans allow you to use the internet, navigate the web and run applications. To keep charges reasonable, you should sign up for a global data plan for a set rate before you go abroad. Otherwise, you may be charged an exorbitant amount of money for each megabyte of data you use.
Put the phone in "flight" or "airplane" mode when not in use. This prevents the phone from receiving calls, texts or emails, according to CNN.
Make calls through the web. To keep your phone charges reasonable, consider using a web-based phone service. Many of these service providers, such as Google Voice and Skype, offer free calling or a low per minute rate on international calls.
Replace the SIM card in your phone with a version from the country you are visiting. This allows you to receive calls for free and make calls at a cheaper rate. You must first request that your phone be unlocked by your service provider.
