1. What is an eSIM?

An eSIM (embedded SIM) is a virtual SIM card embedded directly into your device — such as smartphones, tablets, smartwatches, or laptops — eliminating the need for a physical SIM. With an eSIM, you can activate and use mobile services simply by scanning a QR code or entering a code manually — no need to insert or replace a SIM card.

► Key advantages of using eSIM:

• No physical card required – no risk of damage or loss

• Quick activation – ready to use in just a few minutes

• Flexible network switching – change providers without replacing the SIM

• Ideal for travelers – buy an international eSIM online and activate it instantly

• Dual SIM capability – use alongside your existing physical SIM

5. Things to Keep in Mind

• Most devices allow multiple eSIM profiles, but only 1–2 can be active at once

• Do not delete your eSIM unless you’re certain you no longer need it

• For travel eSIMs, enable the eSIM after landing in Vietnam to ensure optimal coverage

• Before activation, turn off your primary SIM or switch it to Roaming Off mode to avoid unexpected charges

eSIM is the future of mobile connectivity — faster, smarter, and built for global travelers. In just a few clicks, you can stay connected, save time at the airport, and avoid the hassle of finding a SIM vendor.
