Verizon TravelPass in Vietnam (2026): The $12/Day Math vs a $4 eSIM
Verizon in Vietnam: what roaming really costs in 2026, when the pass is worth it, and when a $4 eSIM wins.
Key takeaways
- Verizon works in Vietnam: Verizon's TravelPass charges roughly $12 for each day you actually use data abroad (as of 2026; check your plan) (details below).
- A 10-day trip on Verizon's roaming option: $120 (10 x $12 TravelPass days). The same trip on a travel eSIM: from about $4-20 total.
- Roaming keeps your US number live for calls and texts; a data eSIM plus your normal SIM in dual-SIM mode gets you both for less.
- Whatever you pick, decide before you fly. Airport-arrival panic is where the worst money is spent.
- Carrier prices change; confirm your plan's current terms before travel.
Which network you get, and what it really costs
In Vietnam the Fizen eSIM roams on Viettel Mobile (4G). Vietnam is sold inside the South-Eastern Asia plan, which covers 18 countries. At 128 kbps you can still send messages and load map tiles, but not hold a video call.

Prices and carrier read from the Fizen catalogue on 23 September 2026. Data only, no calls or SMS.
Prices are before the welcome credit. A new user who opens the eSIM tab in the Fizen app for the first time gets US$10 of eSIM credit automatically, with no code, valid for 12 months. The app shows how much of it comes off your order. Paying by card on the web works too, but the credit only applies in the app.
What Verizon TravelPass costs in Vietnam
Verizon's TravelPass charges roughly $12 for each day you actually use data abroad (as of 2026; check your plan). It taps your domestic allowance with a daily high-speed cap, after which speeds are slowed for the rest of the day. There is also a monthly international plan for longer trips. You are only billed on days your phone touches the network, which sounds friendly until a two-week trip quietly becomes $150+.

The 10-day trip math
When carrier roaming actually makes sense
TravelPass earns its keep on short trips where you need your US number live for calls and texts, bank verifications, or work. For a weekend, $24-36 of zero-effort connectivity is honestly fine. It stops making sense the day your trip gets longer than about four days, which is when the eSIM math takes over.
The eSIM route, in three steps
- Before you fly: buy a Vietnam eSIM in the app and install it on home Wi-Fi (5 minutes).
- On landing: switch the eSIM on for data, leave your Verizon SIM active for calls and texts, and turn its data roaming off so no surprise pass gets triggered.
- Pay your way: Fizen eSIMs are payable by USDT, Stripe, Apple Pay or Google Pay, across 150+ countries from the same app.

How much does Verizon charge for roaming in Vietnam?
As of 2026, It taps your domestic allowance with a daily high-speed cap, after which speeds are slowed for the rest of the day. A 10-day trip lands around $120 (10 x $12 TravelPass days). Verify current pricing on your plan before you fly.
Is an eSIM cheaper than Verizon roaming in Vietnam?
For most trips, dramatically. A Fizen travel eSIM for Vietnam starts around $4, and even a heavy-use plan for the whole trip usually costs less than two days of a $12/day pass. The trade-off: an eSIM is data-only, so keep your Verizon SIM active for calls and texts.
Can I use an eSIM and keep my number?
Yes, that is the standard setup: your Verizon SIM stays in for calls, texts and bank OTPs (with data roaming off), and the travel eSIM handles all data. Any recent iPhone or flagship Android runs both at once.
