7 Things to Do Before Your Flight (Including Getting Your eSIM)

You’re about to pay $400 for a mediocre sandwich at the airport. But that’s nothing compared to what your carrier wants to charge for international roaming. Smart travelers handle the essentials before they leave home, saving both money and sanity.

Here are seven things you should tick off your list before heading to the airport. Your future self will thank you when you’re not scrambling for WiFi passwords or paying $15 per megabyte.

1. Download Your eSIM Before You Leave

Your carrier’s roaming fees are designed by people who clearly never travel. $10 per day for 100MB? That’s enough data to send exactly three photos to your family.

Get your eSIM sorted before you pack your bags. We send you a QR code instantly – scan it, and you’re ready to go. The moment you land, you’ll have full-speed data at up to 70% less than roaming fees. Plans start from $4 for short trips or $192 for 50GB over 180 days.

No airport SIM card shops. No plastic waste. No standing in queues while jet-lagged. Just working internet when you need it most.

2. Check Your Passport Expiry (And Entry Requirements)

Your passport needs six months of validity for most countries. This isn’t a suggestion – it’s immigration law. Check the expiry date now, not at check-in.

While you’re at it, verify visa requirements. Some countries offer visa-on-arrival for tourists but require advance applications for business travelers. The rules change frequently, so check official government sources, not travel blogs from 2019.

Download digital copies of your passport, visa, and travel insurance to your phone. Store them in a folder that works offline. When officials ask for documents, you want them in your hands, not stuck behind a hotel WiFi login screen.

3. Set Up Mobile Banking and Notify Your Bank

Banks have fraud detection systems that assume you never leave your hometown. Use your card in Prague, and they’ll freeze your account faster than you can say “I’m traveling.”

Call your bank or set travel notifications through their app. Include all countries you’ll visit, plus any connection cities. If you’re flying London to Bangkok via Dubai, tell them about Dubai too.

Download your banking apps and set up mobile payment systems before you leave. Make sure you remember your PIN – contactless doesn’t work everywhere, and ATM withdrawals still need those four digits you never use at home.

4. Download Offline Maps and Essential Apps

Google Maps works offline if you download the areas you need. Do this while you have unlimited home WiFi, not when you’re rationing expensive hotel internet.

Download translation apps that work without internet. Google Translate’s camera feature works offline for many languages – useful when restaurant menus look like abstract art.

Get ride-sharing apps for your destination. Uber doesn’t operate everywhere, but local alternatives usually exist. Download them at home where app stores work properly, not in foreign countries where they might be blocked.

5. Pack Your Phone Charger in Your Carry-On

Airlines lose 25 million bags per year. Your checked luggage might go to Bangkok while you’re in Berlin. Always pack phone chargers, adapters, and cables in your carry-on.

Bring a portable battery pack. Airport charging stations are either broken, occupied, or designed by people who hate travelers. A 10,000mAh battery will keep your phone alive for days.

Check plug types for your destination. European plugs won’t fit American sockets, no matter how hard you push. Buy adapters before you travel – airport shops charge $30 for $3 worth of plastic.

6. Arrange Airport Transportation

Research transport from the airport to your accommodation. Official airport shuttles usually cost more but run on schedule. Public transport is cheaper but might not operate late at night.

If you’re taking rideshares, find the designated pickup areas. Every airport hides these in different locations, usually as far as possible from where you want to be.

Download parking apps if you’re driving to the airport. Long-term parking fills up during peak seasons, and walking two miles to the terminal with luggage builds character you didn’t ask for.

7. Check In Online and Download Boarding Passes

Online check-in opens 24 hours before departure for most airlines. Do it immediately. Choose your seats, add any extras you need, and download your boarding passes to your phone.

Take screenshots of your boarding passes and save them to your photos. QR codes occasionally glitch, and airplane mode doesn’t help when gate agents need to scan your phone.

If you have connecting flights, grab boarding passes for all segments. Some airlines issue them automatically, others make you collect them during connections. Know which situation applies to your trip.

Travel Smart, Not Hard

These seven steps take 30 minutes at home but save hours of frustration abroad. The biggest impact comes from sorting your mobile data situation properly.
