eSIM vs Local SIM Card: Which Should You Get for Travel?

The days of hunting for a SIM card vendor at 2am in a foreign airport are numbered. eSIMs have transformed how travelers stay connected — but they're not always the best choice.

Here's an honest comparison to help you decide.

What's an eSIM?

An eSIM is a digital SIM card embedded in your phone. Instead of swapping a physical card, you scan a QR code and activate a data plan instantly. No tools, no tiny trays, no losing your home SIM.

Supported devices: iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3+, and most flagship phones from 2020 onward.

The Comparison

Cost

	eSIM	Local SIM
7-day plan	$5–15	$3–8
30-day plan	$15–40	$5–15
Unlimited data	$20–50/week	$10–25/month

Winner: Local SIM — typically 2–3x cheaper, especially for longer stays.

Convenience

	eSIM	Local SIM
Setup time	2 minutes from home	15–30 min at airport
Language barrier	None	Sometimes
Available before arrival	Yes	No
Keep home number	Yes (dual SIM)	Depends on phone

Winner: eSIM — set up from your couch before the flight.

Coverage & Speed

eSIM providers like Airalo and Holafly partner with local carriers, so coverage is usually identical. However:

• Local SIMs sometimes get priority on congested towers
• eSIMs may have slower speeds in rural areas in some countries
• Local SIMs give you a local phone number (needed for some apps)

Winner: Local SIM — marginal edge in speed and you get a local number.

Data Limits

• Airalo: 1GB to 20GB plans, no unlimited
• Holafly: Unlimited data (but may throttle after heavy use)
• Local SIMs: Genuinely unlimited in most countries for $10–20/month

Winner: Tie — depends on your usage.

Our Recommendation

Get an eSIM if:

• You're visiting for under 2 weeks
• You want connectivity the moment you land
• You're visiting multiple countries (regional eSIMs cover 10+ countries)
• You don't want to deal with airport SIM vendors

Get a local SIM if:

• You're staying 2+ weeks in one country
• You need a local phone number (for Grab, food delivery, banking apps)
• You're on a tight budget
• You're in a country where eSIM coverage is limited

The power move: Both

If your phone supports dual SIM (most modern phones do), use an eSIM for data and keep your home SIM for calls/texts. Buy a local SIM only if you need a local number for app registrations.

Best eSIM Providers

1. Airalo — Widest country coverage (200+ countries), flexible plans, good app
2. Holafly — Best for unlimited data, but fewer countries
3. Nomad — Competitive pricing, good for Asia
4. Ubigi — Strong European coverage

Country-Specific Notes

• Japan: eSIM works perfectly. Local SIMs are overpriced at airports.
• China: You need a VPN regardless. eSIM + VPN is the easiest setup.
• Vietnam: Local SIMs are incredibly cheap ($3 for 30 days). eSIM is unnecessary unless convenience matters.
• Indonesia: Local SIM registration requires passport scan at the store.
• Thailand: Both work well. Airport SIM deals are competitive.

Bottom Line

For most travelers making a 1–2 week trip, an eSIM is the smart choice. The convenience of having data the second you land is worth the small premium. For digital nomads or month-long stays, a local SIM saves real money.
