What you need to know about eSIMs in Vietnam
Getting online in Vietnam is simple with a travel eSIM. You install the plan before you leave, scan a QR code, and connect to a local network the moment you land — no hunting for a SIM kiosk and no roaming bill from your home carrier. In major cities and tourist areas you'll generally get reliable 4G, with 5G in many urban centres; coverage naturally thins out in remote and rural areas, whichever provider you choose.
How much data you need depends on your trip: 1–3 GB a week is plenty for maps, messaging and social media, while streaming or sharing a hotspot calls for 10 GB or more — or an unlimited plan. Rather than pay your operator's roaming rates, compare the plans above by their real price-per-gigabyte; the cheapest option is often a fraction of a roaming pass. Your primary number, calls and WhatsApp keep working, because the eSIM simply adds a second line for data.
