Treat connectivity as a plan
Your first connection can fail because of airport Wi-Fi congestion, carrier roaming delays, eSIM activation timing, or payment verification. Prepare one primary connection and one offline fallback.
Pre-flight checklist
- Confirm your phone is unlocked if you plan to use eSIM or a local SIM.
- Save activation instructions and QR codes offline.
- Download map, airline, hotel, payment, and translation apps before leaving home.
- Save hotel address and emergency phrases for offline use.
If data fails after landing
- Try your prepared mobile data plan
Activate roaming, eSIM, or SIM using your saved instructions.
- Use airport or hotel Wi-Fi briefly
Use Wi-Fi only long enough to activate service or contact your hotel.
- Switch to offline cards
Show saved hotel, taxi, payment, and emergency phrases while you recover.
