eSIMs offer a hassle-free, prepaid, and fully digital solution for tourists who want to stay connected across Vietnam’s vibrant cities and breathtaking rural areas.

This is particularly helpful if your phone supports dual SIM mode, so you can keep your original number while using your Vietnam eSIM for data.
