Why a pre-flight checklist?
The plane is no longer a dead zone for data; Airlines offer Wi-Fi and when you land, the local network is usually saturated. A well-prepared mobile avoids surprises such as loss of signal, unexpected battery consumption or inability to activate the eSIM. This step-by-step list is intended for travelers who want to land with the network ready to use.
The 5 essential settings
- Update the operating system and network apps.
The most recent versions fix roaming bugs, improve eSIM management and add support for new 5G bands. On iPhone, go to Settings→General→ Software Update. On Android, go to Settings→System→ System Updates or your manufacturer's menu.
- Activates data roaming and emergency mode.
Many travelers turn off roaming to save money, but forgetting to turn it back on before takeoff cuts off the signal upon landing. On iPhone, the option is in Settings→Mobile Data→Options→ Data Roaming. On Android, search for Mobile networks→ Roaming. Additionally, enable Emergency Roaming (satellite mode) if your device supports it; This allows for distress calls when the terrestrial network fails.
- Sets airplane mode and automatic reconnection.
During takeoff and landing, regulations require airplane mode to be activated. Configure your mobile so that, when you deactivate airplane mode, automatically reconnects Wi-Fi and Bluetooth. On iPhone, turn on Connect to Wi-Fi networks automatically under Settings→Wi-Fi. On Android, the option is usually found in Settings→Connections→Wi-Fi→Automatically reconnect. This way you won't have to manually search the airport network.
- Check the APNs and eSIM profile.
The APN (Access Point Name) define how your mobile accesses the mobile internet. Some airlines require specific APNs for their inflight Wi-Fi; others, for the destination eSIM. On iPhone, check the data under Settings→Mobile data→Options→ mobile data network. On Android, go to Settings→Mobile networks→ Access Point Names. Additionally, open the ILoveEsim app and confirm that the target profile is active and pre-loaded, not just downloaded.
- Optimizes the battery for long trips.
A cell phone that goes off in the middle of the airport is a nightmare. Turn on Power Saving (iPhone: Settings→Battery→Low Power Mode; Android: Settings→Battery→Power Saving ) and disable features you won't use, such as Background Refreshes and Auto Brightness. If your device supports airplane mode with Wi-Fi, use it to maintain connectivity without consuming the mobile's radio frequency.
Quick comparison: iPhone vs Android
| Configuration | iPhone (iOS) | Android (varies by manufacturer) |
|---|---|---|
| OS Update | Settings→General→Software Update | Settings→System→System Updates |
| Data roaming | Settings→Mobile data→Options→Data roaming | Settings→Mobile networks→Roaming |
| Airplane mode + reconnection | Settings→Wi-Fi→Automatically connect | Settings→Connections→Wi-Fi→Automatically reconnect |
| APN and eSIM | Settings→Mobile data→Options→Mobile data network | Settings→Mobile networks→Access point names |
| Battery Saver | Settings→Battery→Low Power Mode | Settings→Battery→Power Saver |
Expert tricks (don't pass them up!)
Warning: If you disable Data Roaming and the eSIM is configured as primary , your mobile will still try to use the local operator's network and you may incur unexpected roaming charges. Make sure the destination eSIM is the active SIM before turning off airplane mode.
Printable checklist (to carry in your suitcase)
- ✔️ Updated operating system.
- ✔️ Data roaming and emergency roaming activated.
- ✔️ Airplane mode programmed to activate and deactivate automatically.
- ✔️ Verified APN and active destination eSIM profile.
- ✔️ Battery in saving mode and brightness adjusted.
FAQ
Do I need to connect the eSIM before taking off?
It is not mandatory, but activating it in advance avoids delays when landing. In the ILoveEsim app, select “Activate now” and confirm that the profile shows “Ready” before the flight.
Does airplane mode interrupt the eSIM signal?
Yes, airplane mode cuts off all the mobile radios, including the eSIM. That is why it is key to schedule its deactivation just after landing so that reconnection is automatic.
Can I use data from the airplane's Wi-Fi network while in airplane mode?
Some airlines allow you to enable Wi-Fi without turning off airplane mode. Look for the “Wi-Fi in airplane mode” option in the network settings; If available, activate it and keep the rest of the radios off.
What happens if my phone doesn't recognize the eSIM upon arrival?
First, verify that the profile is active in the ILoveEsim app. If it still does not work, restart the mobile and check the APN. In rare cases, a pending software update may be the cause.
How do I prevent my phone from consuming data in the background when I arrive at the airport?
Disable the “Background Updates” option for apps you don't need immediately (social networks, podcasts). You can also use “Data Saver” mode during the first few minutes after landing.
