If your eSIM is not connecting automatically, the most common reasons are delayed network registration, Airplane Mode still enabled, the eSIM line turned off, wrong mobile data settings, roaming disabled, or weak local coverage.
This often happens right after landing, when travelers expect instant service.
Quick answer: Turn Airplane Mode OFF, confirm the eSIM is ON, select it for mobile data, enable roaming if required, and wait a few minutes for network registration.
Important: Automatic connection depends on local partner networks, destination coverage, device model, signal conditions, and our General Conditions.
Why Automatic Connection Can Take Time
When you enter a new country, your phone may need time to:
- Search available partner networks
- Register the eSIM on a local carrier
- Authenticate service access
- Apply roaming settings
- Switch from old networks to new ones
Tip: Waiting 2–5 minutes after landing is often normal before changing settings.
