Quick Answer: Holafly Is the Best eSIM for Travel
Why Holafly wins:
- ✅ Truly unlimited data (no caps, no throttling)
- ✅ Works in 200+ countries
- ✅ Never run out mid-trip
- ✅ Always reachable via WhatsApp
- ✅ Annual plan: $475/year with THEDUFRESNES (32% off)

Why data cap eSIMs fail:

- ❌ Need to buy multiple eSIMs per trip
- ❌ More expensive long-term
- ❌ Unreachable when data depletes
- ❌ Constant stress monitoring usage
The best eSIM is the one you never think about. That's Holafly.
Why Unlimited Data Matters More Than You Think
You'll Use More Data Than Expected
What we actually use traveling:
- Google Maps: 200-500MB per day
- WhatsApp calls: 300-500MB per day
- Instagram Stories: 500MB-1GB per day
- Photo backups (iCloud/Google): 500MB-1GB per day
- Email, browsing, apps: 300-500MB per day
- YouTube uploads (our work): 2-5GB per day
Daily total: 3-8GB
Monthly total: 90-240GB
With data caps: You're buying new eSIMs every week.
With Holafly unlimited: You don't even monitor usage.
Being Unreachable Is Dangerous
Here's what people don't realize about data cap eSIMs:
When you run out of data abroad, you can't receive WhatsApp calls.
Your home SIM is still active (dual SIM), but:
- WhatsApp requires data to work
- No data = calls don't connect
- You're completely unreachable
- You don't even know someone tried to contact you
This happened to us during our apartment fire in Da Nang:
Our property manager called Shayna on WhatsApp about the fire. Because we had Holafly unlimited data active, the call went through immediately. We booked a Grab, got home in 8 minutes, evacuated our 3 chihuahuas, and relocated to Hue same day.
If we'd had a data cap eSIM and run out:
- Property manager's call wouldn't connect
- We'd be unreachable for hours
- Our dogs trapped longer
- More damage
Unlimited data isn't luxury - it's essential for safety.
Why Data Cap eSIMs Are a False Economy
The "Cheap" eSIM That Costs More
Airalo/Saily typical pricing:
- 3GB: $15
- 10GB: $30
- 20GB: $50
Sounds cheap until you do the math:
Week 1-2: Use 3-5GB
Week 3: Buy another $30 eSIM
Week 4: Buy another $30 eSIM
Monthly cost: $60-90
Plus the hassle:
- Installing new eSIM mid-trip
- Waiting for activation
- New phone number each time
- Losing connection during transition
Holafly Unlimited Is Actually Cheaper
Holafly monthly plan with THEDUFRESNES:
- Regular: $65/month
- With code: $58.50/month
- Truly unlimited data
Compare:
- Buying data cap eSIMs repeatedly: $60-90/month
- Holafly unlimited: $58.50/month
Holafly is cheaper AND you get unlimited data.
Annual Plan: Best Value for Frequent Travelers
Holafly annual plan:
- Regular: $699/year
- With THEDUFRESNES (32% off): $475/year
- That's $39.58/month for unlimited data in 200+ countries
Perfect for:
- Digital nomads
- Full-time travelers
- Frequent business travelers
- Anyone taking 3+ international trips per year
Savings vs buying monthly plans:
- 12 months at $58.50 = $702/year
- Annual with THEDUFRESNES = $475/year
- You save $227/year

Actually unlimited.

Same eSIM worked everywhere automatically. No swapping, no buying new eSIMs at each border.

New Holafly feature launched 2026:

What this means:

We've had signal:

Coverage is genuinely excellent.
Why Other eSIMs Don't Compare
Data Cap eSIMs (Airalo, Saily, etc.)
The fundamental problem:
They give you 3GB, 10GB, or 20GB and call it a day.
This doesn't work for:
- Modern travel (everything needs data)
- Working remotely
- Content creation
- Video calling family
- Real-time navigation
- Cloud photo backups
- Staying constantly reachable
You will run out. Then you're buying more. Then it's more expensive than unlimited.
Plus the safety issue: When you run out of data, you can't receive WhatsApp calls. You're unreachable until you find WiFi and buy more data.
Local SIM Cards
Why we stopped buying local SIMs:
Before the trip:
- Research which carrier is best
- Find SIM shop at airport
- Often closed or hard to find
- Long queues
At the shop:
- Language barriers
- Confusing plans
- Need passport
- Takes 30-60 minutes
- Expensive tourist pricing
After purchase:
- Another SIM to keep track of
- Another phone number nobody has
- Expires when you leave country
- Can't reuse in next country
With eSIM (Holafly):
- Buy online before trip
- Install at home
- Activates when you land
- Works in next country too
- Keep same eSIM forever
eSIMs are simply better than physical SIMs.
