'Best eSIM for Vietnam 2026: Prices, Speeds & Which to Buy'

Quick Answer

Airalo wins for Vietnam in 2026. At ~$13 for 3GB on Viettel's network, it gives you the best coverage across the country — including Da Nang, Hoi An, and central Vietnam where other eSIMs on Mobifone struggle. For heavy data users, Holafly's unlimited plan ($69/month) is the backup pick. Download the Airalo app, buy the "Vietnam" plan, scan the QR code, and you're online before you clear immigration at Noi Bai or Tan Son Nhat.

## Airalo — Best Overall

Network: Viettel (best coverage in Vietnam)
Why it wins: Viettel gives you reliable signal in cities *and* places like Da Nang, Hoi An, Ha Long Bay, and the central highlands. Other providers using Mobifone drop off fast outside urban areas.

## Nomad — Best Mid-Range Option

Network: Viettel
Why consider it: Nomad offers slightly more data per dollar than Airalo on some plans and also uses the Viettel network. Good for 1-2 week trips where 5-10GB is the sweet spot.

### Pricing

|------|------|-------|------|
| 7 days | 1GB | $6 | $6.00 |
| 15 days | 3GB | $12 | $4.00 |
| 30 days | 5GB | $18 | $3.60 |
| 30 days | 10GB | $32 | $3.20 |
| 30 days | 20GB | $48 | $2.40 |

### Pros & Cons

## Holafly — Best for Unlimited Data

Network: Mobifone
The trade-off: Unlimited data sounds great, but Holafly routes through Mobifone instead of Viettel. Mobifone is solid in Hanoi and HCMC (10-30 Mbps), but coverage drops in rural areas, central Vietnam, and smaller towns. If you're staying in major cities, this is less of an issue.

### Pricing

| Plan | Data | Price |
|------|------|-------|
| 5 days | Unlimited | $19 |
| 10 days | Unlimited | $34 |
| 15 days | Unlimited | $47 |
| 20 days | Unlimited | $54 |
| 30 days | Unlimited | $69 |

### Pros & Cons

Pros
- Truly unlimited data — no overage worries
- Great for video calls, streaming, heavy hotspot use
- Simple pricing — pick your days, done
- Good referral discounts available

Cons
- Mobifone network — weaker outside Hanoi/HCMC
- Most expensive option per day
- Speeds can throttle during peak hours
- No option to switch to Viettel

Best for: Heavy data users staying in Hanoi, HCMC, or other major cities who don't want to think about data limits.

## Saily — Best for Short Trips

Network: Mobifone
Where it fits: Saily is a solid choice for 3-7 day trips where you need 1-5GB and don't want to overthink it. Same Mobifone caveat as Holafly — stick to cities.

### Pricing

| Plan | Data | Price | $/GB |
|------|------|-------|------|
| 7 days | 1GB | $7 | $7.00 |
| 7 days | 3GB | $13 | $4.33 |
| 30 days | 5GB | $20 | $4.00 |
| 30 days | 10GB | $35 | $3.50 |
| 30 days | 20GB | $58 | $2.90 |

### Pros & Cons

Pros
- Simple, fast setup
- Competitive on short-term plans
- Good app experience
- Backed by a reputable company (Surfshark team)

Cons
- Mobifone only — same rural coverage issues as Holafly
- Pricier than Airalo on equivalent plans
- Fewer plan variations
- Smaller community/fewer reviews for Vietnam specifically

Best for: Short city-based trips where you need a quick, no-fuss eSIM and won't leave Hanoi or HCMC.

## How to Choose the Right Vietnam eSIM

### Decision framework

Step 1: How long is your trip?
- Under 7 days: Airalo 1GB ($5) or Saily 3GB ($13)
- 1-4 weeks: Airalo 3-10GB ($13-$35)
- 1+ month: Airalo 20GB ($55) or Holafly unlimited ($69)

Step 2: Where are you going?
- Cities only (Hanoi, HCMC): Any provider works fine
- Da Nang, Hoi An, central Vietnam: Pick Airalo or Nomad (Viettel)
- Rural/remote areas: Airalo on Viettel is the safe choice

Step 3: How much data do you need?
- Light use (messaging, maps, email): 3-5GB is plenty
- Remote work (Zoom, Slack, browsing): 10-20GB
- Heavy use (streaming, tethering, video): Holafly unlimited

Step 4: What's your budget?
- Under $15: Airalo 3GB or Nomad 3GB
- $15-$35: Airalo 5-10GB, Nomad 5-10GB
- No budget cap: Holafly unlimited

### The short version

If you're visiting Vietnam and want one recommendation: Airalo on Viettel. It's the cheapest reliable option with the best network. Buy a bigger plan than you think you need — topping up mid-trip costs more.

### Airport SIM vs eSIM

You can buy a physical SIM at Noi Bai (Hanoi) or Tan Son Nhat (HCMC) for around $5-10 with 3-5GB. But the eSIM route is faster (no queue, no SIM swap) and gives you your number before you land. Physical SIMs are only worth it if your phone doesn't support eSIM.

## FAQ

### Does Vietnam support eSIM?

Yes. Viettel, Mobifone, and Vinaphone all support eSIM. Most phones from 2020 onward (iPhone XR and later, Samsung S20+, Google Pixel 4+) work with eSIM in Vietnam. Check your phone settings — if you see "Add eSIM" or "Download SIM," you're good.

### Which eSIM has the best coverage in Vietnam?

Airalo and Nomad use Viettel, which has the best nationwide coverage — including rural areas, central Vietnam (Da Nang, Hoi An), and mountainous regions. Holafly and Saily use Mobifone, which is strong in cities but weaker outside them.

### How fast is mobile data in Vietnam?

4G/LTE speeds range from 15-40 Mbps in Hanoi, HCMC, and Da Nang. 5G is rolling out in Hanoi and HCMC in 2026, with speeds up to 150 Mbps where available. Rural areas see 5-15 Mbps on 4G. Viettel generally delivers the most consistent speeds.

### Can I use an eSIM for Vietnam on iPhone?

Yes. Any iPhone from XR/XS (2018) and later supports eSIM. iPhone 13+ supports dual eSIM — you can keep your home SIM active while using a Vietnam eSIM for data. Android users: Samsung Galaxy S20+, Google Pixel 4+, and most 2022+ mid-range phones support eSIM.

### Is Holafly unlimited data really unlimited?

Yes, Holafly's Vietnam plans are unlimited data. However, speeds may throttle during congestion (typically evenings in Hanoi/HCMC). The bigger issue is that Holafly runs on Mobifone, so coverage outside cities is weaker than Airalo's Viettel-backed plans.

### Do I need a VPN in Vietnam?

A VPN is recommended for accessing certain websites and maintaining privacy on public Wi-Fi. Remote workers should use one regardless of country — see our best travel insurance for digital nomads guide for broader digital nomad infrastructure tips.
