Why this one

The Galaxy S20 doesn't need a 1 GB plan, and most people don't burn through unlimited.

The Galaxy S20 natively supports eSIM with dual-SIM standby. Installation is a 60-second QR scan — see the install guide for the exact tap sequence.

In Vietnam, our wholesale routes ride Viettel, Vinaphone, MobiFone — 40 – 110 Mbps urban · 75 ms RTT. The 14-day window matches the median trip length we see for this destination, and 15 GB is what most travelers actually use — anything more is paid breathing room you don't draw on.

If your trip is shorter or longer, the Vietnam page has the alternates.

Galaxy S20 in Vietnam

Before you buy.

For most Galaxy S20 travelers in Vietnam we recommend the 14-day plan with 15 GB. It matches the median trip length we see for Vietnam, and Galaxy S20 runs eSIM cleanly so the only real decision is how much data you need.
We picked 15 GB rather than unlimited because most Galaxy S20 travelers in Vietnam never reach it — unlimited would be paid breathing room you do not draw on. If you stream or tether heavily, the unlimited option is one tap away on the country page.
Maps, messaging, and email on Galaxy S20 sip data; video calls and streaming are what add up. Our pick — 15 GB over 14 days — covers a normal working trip to Vietnam with margin. Heavy streamers should size up.
Our Galaxy S20 pick for Vietnam is $35 for 14 days — one up-front charge, no subscription, no surprise roaming bill. Stripe adds local tax based on your billing country at checkout.
In Vietnam, Galaxy S20 routes on Viettel, Vinaphone, and MobiFone — 40 – 110 Mbps urban · 75 ms RTT. It hands off to whichever has the strongest signal where you are; you never pick the carrier manually.
After checkout the QR arrives by email; on Galaxy S20 it is Settings → Network & internet → SIMs → Download a SIM → scan. Under two minutes. The full step-by-step is on the Galaxy S20 install guide.
The 14-day plan is our default, not the only option. The Vietnam page has shorter and longer windows, and you can top up the same Galaxy S20 eSIM mid-trip without reinstalling if you run low.
Full refund if the Vietnam eSIM fails to activate on Galaxy S20; half refund if it activates but underperforms on Viettel, Vinaphone, and MobiFone. One click from your dashboard — no email thread.
