Good news! Most recent smartphone models are fully compatible with eSIM technology. If you're rocking an iPhone XS or newer, a Samsung Galaxy S20 series or later, or a Google Pixel 4 and up, you're likely all set. Some newer Xiaomi and Huawei models also support eSIM. The key is to ensure your phone is unlocked by your home carrier and supports eSIM functionality. This will allow you to connect effortlessly to local networks across Vietnam, Laos, and beyond.
