Install the eSIM before you leave. Land in Vietnam already connected.
Vietnam is outside the EU — so roaming from Italy or other European countries is usually pay-per-use or comes with costly day-passes, often with a hidden FUP after just a few GB. With a BLIVALE Vietnam Unlimited eSIM: install in 2 minutes from home, truly unlimited data on Viettel, Vinaphone and MOBIFONE, no Fair Usage Policy, no speed limit, hotspot included — for the entire duration of the plan. Automatic activation on arrival, no contract or ID document required.
1. Mobile network in Vietnam: Viettel, Vinaphone and MOBIFONE
Vietnam has a mobile market dominated by three major national operators with extensive infrastructure. The BLIVALE Vietnam eSIM relies on Viettel, Vinaphone and MOBIFONE, ensuring the widest possible coverage both in major cities and in the most popular tourist destinations like Ha Long Bay and Phu Quoc.

Real speeds in Vietnam 2026: in major cities like Hanoi, Ho Chi Minh City and Da Nang, Viettel's 5G typically reaches 150-300 Mbps download. On 4G LTE, common in coastal tourist areas and smaller towns, typical speeds are 20-60 Mbps — more than enough for streaming, video calls and GPS navigation.
2. Cost comparison: roaming vs eSIM in Vietnam
Vietnam is not part of the EU, so for European travelers roaming is almost always pay-per-use or requires a specific paid option. Even "world roaming" packages from carriers often apply strict FUP after just a few GB. Here's a real comparison for 7 days.
| Solution | Estimated cost 7 days | Data included | Notes |
|---|
Pay-per-use roaming (Italian/EU carriers) Extra-EU rate, pay-per-use or day pass |
€40–90+ |
Limited or pay-per-use |
Vietnam is outside the EU: many carriers apply high pay-per-use rates or day-passes of €6-13/day. |
"World roaming" option with hidden FUP Paid add-on from some carriers |
€15–30 per week* |
Limited data (FUP) |
*FUP applied: speed reduced to 128-256 kbps after the included threshold. Not truly unlimited. |
Local Vietnamese SIM Viettel, Vinaphone — airport or store |
€8–20 |
Limited data (5-15 GB) |
Requires queuing at the airport or store, often with ID and manual activation. Physical SIM swap. FUP after the threshold. |
BLIVALE Vietnam Unlimited eSIM ★ recommended |
from €19.70 |
Truly unlimited, no FUP |
QR code by email within 1-4 hours. Install from home in 2 min. Automatic activation on arrival. Hotspot included. |
Watch out for FUP in roaming options for Vietnam: even when a European carrier offers an add-on for Southeast Asia, always check the included FUP threshold. Once exceeded, speed often drops to 128-256 kbps — unusable for maps, video calls or social media during your trip. The BLIVALE Vietnam eSIM has no FUP thresholds.
3. Why an eSIM beats a local SIM in Vietnam
No queuing at Hanoi or Ho Chi Minh City airport
Vietnamese airports have SIM sales points — but with frequent queues, especially during peak hours and high tourist season. Buy the eSIM from home, install it in 2 minutes, and you're already online when you land. No searching for a Viettel or Vinaphone store in a foreign country, no ID to show.
Automatic activation on arrival
The BLIVALE Vietnam eSIM activates automatically as soon as you land and turn off airplane mode, connecting to the best available network among Viettel, Vinaphone and MOBIFONE — with no additional setup.
Your home number stays active
The phone uses both SIMs at the same time — the physical SIM for calls and SMS (including banking OTPs), the BLIVALE eSIM for data. Remember to turn off data roaming on your home SIM before departure.
4. Vietnam Unlimited eSIM plans: 7, 15, 20 and 30 days
The Vietnam Unlimited eSIM offers truly unlimited data, relying on the main local networks Viettel, Vinaphone and MOBIFONE. This is a premium profile that applies no Fair Usage Policy (FUP) and no speed limits, ensuring consistent high-speed browsing and an automatic reset of traffic every 24 hours. Hotspot is included to share data with other devices, and activation is instant via a QR code sent by email within 1-4 hours of purchase.

7. Practical tips for your trip to Vietnam
Essential apps for Vietnam
Grab — the go-to app for taxis, motorbike-taxis and food delivery, widely available in major cities and tourist areas. Offline Google Maps — download maps of the areas you visit, especially for excursions to more remote regions like Sapa or Ha Giang. WhatsApp — useful for staying in touch with home, although locally many Vietnamese use Zalo.
Working remotely or staying connected from Vietnam
Hotspot is included at no extra cost on all Vietnam Unlimited plans. Perfect for those working remotely during the trip or who want to stay in touch back home via video calls on WhatsApp, Teams and Zoom — all fully supported with no data thresholds to monitor.
Zero worries about contracts or documents
Unlike a local SIM, the BLIVALE eSIM requires no contract and no ID document: buy online, receive the QR code by email and install the profile on your own, even before you leave.
Tip for multi-destination trips: if your itinerary covers several cities or regions (for example Hanoi → Ha Long Bay → Da Nang → Ho Chi Minh City), the 20 or 30-day plan is the most convenient choice — a single eSIM works throughout Vietnam with no reconfiguration. No need for a different SIM at every stop of your trip.
