Travel apps
An eSIM has quietly become the first thing experienced travellers set up, because it removes an entire arrival ritual: no queue at the airport kiosk, no passport photocopy, no SIM tray and no lost home number. You buy a data plan before you fly and land already connected. The apps differ mainly in coverage and in how honestly they price a regional plan versus a single-country one.
Buy the eSIM before landing, be online at the gate
The most widespread store selling digital SIMs in 200+ countries; installs via QR in 5 minutes and ends the airport SIM queue and outrageous roaming bills. Prices vary by country; regional packages win on multi-country tours.
Before the plane touches down in Tokyo, connect at the gate with the eSIM you loaded at home, not on Narita Wi-Fi.
The pioneer of unlimited-data eSIMs
Most packages offer unlimited data; minding the video-call and hotspot limits, it is soothing for the data-hungry traveler. The choice of those who refuse to count gigabytes.
On a 2-week Europe tour full of work calls, switch to unlimited and stop counting GB.
Affordable eSIM from the NordVPN team
A strong Airalo rival; prices are slightly better in most countries and the app is plain. A 1-minute price comparison against Airalo before buying should be standard practice.
If Airalo's 10 GB for Vietnam looks pricey, catch the same package $2-3 cheaper on Saily.
Millions of shared Wi-Fi passwords on a map
The community pins cafe and venue Wi-Fi passwords to the map; when your data runs out it shows the nearest internet. Passwords can go stale; the hit rate is high in big cities.
The evening your eSIM data dies, back up your adventure with the cafe password two streets over.
Measure your accommodation's internet in numbers, not words
Ookla's speed test; the digital nomad's tool for verifying the host who says "the Wi-Fi is fast". Its country/city averages also help research before relocating.
First thing on entering the Airbnb: speed test. If it reads 5 Mbps, plan your video-call week at a cafe.
Security on open Wi-Fi, access in restricted countries
Encrypts your traffic on airport and cafe Wi-Fi; grants access to services blocked in some countries. The free tier is limited but real and trustworthy; known for its Swiss-based privacy record.
Before opening the banking app on airport Wi-Fi, activate the VPN with one tap.
Almost always, and often by an order of magnitude — roaming is priced for emergencies, a travel eSIM is priced for tourists. The exception is short trips inside a region your home plan already covers at no extra cost. Check whether your phone supports eSIM before you buy, and keep your physical SIM active for calls and one-time codes.
