There are several internet options for international travel: eSIM, pocket WiFi, physical SIM, and international roaming. This guide compares them across price, convenience, speed, and coverage to help you choose the best option.

| Multi-country | One eSIM, many countries | Rent per country | Buy per country | Global (expensive) |
| Hotspot sharing | Yes | Yes (dedicated device) | Yes | Yes |
| Speed stability | Stable, 4G/5G | Depends on device/signal | Stable, 4G/5G | Stable, may throttle |
| Coverage | Same as local network | Need device nearby | Same as local network | Same as local network |
| Activation speed | Auto-connect in 10s | Power on and use | 30+ minutes | Instant |
| Convenience | Scan to install, auto-connect | Need to rent/return device | Queue to buy/swap | No setup needed |
| Price (per day) | $1-2/day | $1-2/day | $3-7/day | $4-14/day |
Short Trip (7-15 days)
eSIM recommended. For 7-15 day trips, expect 5-10GB. eSIM plans cost $11-28, averaging $1-2/day. About 40% cheaper than pocket WiFi and 70%+ cheaper than roaming.
Group Travel (3+ people)
eSIM + hotspot sharing recommended. One phone with eSIM shares hotspot to travel companions, much cheaper than individual purchases. Pocket WiFi also works for groups but requires carrying extra device.
Long Stay (1+ months)
Consider local carrier monthly plans. Use eSIM for emergency internet first, then register a local monthly plan at a carrier store. Keep eSIM as backup.
Emergency Use (1-3 days)
International roaming suits very short emergency use with no preparation needed. But costs are high, not recommended for extended use. If your trip is confirmed, purchase eSIM in advance.
eSIM is the most recommended travel internet solution. Install by scanning a QR code before departure, auto-connect to local carriers on arrival — no queuing. Prices are typically 30-50% cheaper than airport purchases, with full refund if unused.
Key Advantages of eSIM
There are four main travel internet options, each with pros and cons: eSIM (embedded SIM), pocket WiFi (portable router), physical SIM (local purchase), and international roaming (domestic carrier). The best choice depends on trip duration, destination, device compatibility, and budget.
From checking phone compatibility to completing installation — just 3 minutes. Follow the tutorial step by step and set up your eSIM with ease.
View Installation TutorialeSIM installation typically takes only 3-5 minutes. After scanning the QR code, your phone automatically downloads the configuration file, and you can use it once complete. The entire process is very simple with no physical operations required.
We recommend connecting to WiFi during installation, as downloading the configuration file requires a network connection. The file is very small (typically a few KB), so downloading is very fast. After installation, the eSIM is in a pending activation state — enable roaming upon arrival for auto-connection.
Yes, and we recommend installing in advance. The eSIM won't activate immediately after installation — it needs to connect to the local network at the destination before billing starts. We recommend installing before departure and enabling roaming upon arrival.
Common causes include: system version too old, unstable network, unclear QR code. We recommend updating your system to the latest version, ensuring stable WiFi, and scanning in good lighting. If it still fails, contact customer service for a free eSIM re-issue.
iPhone: Settings > Cellular > Select the eSIM > Delete eSIM. Android: Settings > Network & Internet > Mobile Network > Select the eSIM > Remove. After deletion, you'll need a new QR code to reinstall.
Ensure the QR code image is clear and complete, with no obstructions or reflections. Try zooming in on the QR code image and scanning in a well-lit environment. If received via email, save the QR code to your photo album and scan from there. If scanning still fails, contact customer service for a manual activation code.
