"Customers are advised that when traveling outside Guam or the CNMI, they may incur substantial roaming charges when using email, MMS, web browsing and other data services. Many devices, especially Smart Phones, automatically transmit and receive data, and can incur charges, even if no services are intentionally used. You may contact 688-CARE prior to your trip for alternative roaming options."
