The night before an international flight is when everything that should have been done weeks ago suddenly needs to happen in 2 hours. This checklist is ordered by importance — if you only have 30 minutes, do the first five. If you have the full evening, do all 15.
🔴 Critical — Do These or Day 1 Gets Painful
1. Install Your eSIM QR Code Right Now
If you haven't installed your travel eSIM yet, this is your last chance to do it on Wi-Fi without stress. Once you're at the airport or on the plane, you might not have a reliable connection to download the profile or troubleshoot errors.
Settings → Cellular → Add eSIM → Scan QR code from your purchase email. Takes 2 minutes. Do it now.
Don't have one yet? Buy your destination eSIM here — QR arrives in your email in minutes.
2. Download Offline Maps for Your Destination
Google Maps lets you download entire city maps for offline use. Open Google Maps → search your destination city → tap the download button. This works even when you have no signal — useful during flights, in transit zones, and in areas with spotty coverage.
Also download: your hotel's neighborhood, the airport you're arriving at, any day-trip destinations.
3. Screenshot Your Hotel Address in the Local Language
Find your hotel's address written in the local script — Japanese, Thai, Arabic, Chinese — and screenshot it. If your phone dies or you lose signal for any reason, you can show this screen to a taxi driver. Takes 30 seconds, saves enormous stress.
4. Enable Low Power Mode to Make Battery Last Longer on Arrival Day
Arrival days are phone-intensive: Maps running constantly, messages to family, Uber/Grab bookings, hotel check-in photos. Turn on Low Power Mode before you board and your battery lasts 30-40% longer.
5. Confirm Your eSIM Is Set Correctly
- iPhone: Settings → Cellular → confirm your travel eSIM is listed under 'Cellular Plans'
- Check that Data Roaming is ready to be toggled (you'll turn it ON when you land)
- Make sure your home SIM's Data Roaming is OFF (prevents accidental charges)
🟡 Important — Do These If You Have Time

7. Download Google Translate Offline Language Pack
Google Translate → tap the language → download button. The camera translation feature (point phone at Japanese/Thai/Arabic text) works offline for reading, but better with a connection for full features.
8. Take a Photo of Your Passport Information Page
If your passport is lost or stolen abroad, having a clear photo stored in your cloud (Google Photos, iCloud) makes replacement significantly faster at the local embassy. Takes 10 seconds.
9. Enable Find My / Google Find My Device
If your phone is lost abroad, you need this activated now — it can't be turned on remotely after the fact.
- iPhone: Settings → your name → Find My → Find My iPhone → ON
- Android: Settings → Security → Find My Device → ON
10. Charge Every Device to 100%
Phone, earbuds, power bank, smartwatch. Obvious but often forgotten in the rush.
11. Set Up Your Wallet App for Contactless Payment
Apple Pay and Google Pay work globally on Visa/Mastercard where contactless is accepted. Add your travel card or best no-foreign-fee credit card tonight. Reduces cash dependency and transaction fees.
12. Save Offline Copies of Bookings
Download PDF confirmations for: flight, hotel, any activities booked. Save to Apple Files or Google Files app so you can access them without internet. Email screenshots work too.
🟢 Good to Do — If You Still Have Time
13. Tell Your Bank You're Traveling
Many banks still flag foreign transactions as fraud and freeze cards. Log into your banking app or call the number on the back of your card and set a travel notice. Takes 5 minutes, prevents the nightmare of a frozen card abroad.
14. Check Your Destination's Local Emergency Number
Not 911 everywhere. Japan: 110 (police), 119 (ambulance). UK: 999. EU: 112 (works everywhere). Australia: 000. UAE: 999. Save these in your contacts tonight.
15. WhatsApp Message Your Family Group Your Flight Details
Flight number, departure time, expected arrival, hotel name and address. If anything goes wrong mid-journey, the people who need to find you have the information they need. Takes 2 minutes and is one of those things that matters enormously in an emergency.
