Understanding Your US Cell Phone’s Compatibility
Before we dive into the specifics of using your US cell phone in Vietnam, it’s essential to understand the compatibility of your device. Most modern smartphones are designed to work on various frequencies and networks, but it’s crucial to check your phone’s specifications to ensure it can operate on Vietnamese networks.
