Chapter I
Before acquiring any eSIM plan, one must confirm that the device in question possesses both the necessary hardware and the freedom to use third-party carrier profiles.
Navigate to Settings → General → About. Scroll to locate the EID field. Its presence confirms eSIM hardware. Compatible models begin with the iPhone XS (2018) and all subsequent releases.
Navigate to Settings → About Phone. Locate the EID field. Compatible devices include Samsung Galaxy S20 and later, Google Pixel 3 and later, and numerous other modern Android handsets.
A Note on Carrier Lock
Even a device with confirmed eSIM hardware may be restricted by carrier lock — a firmware-level limitation preventing the use of third-party profiles. Contact your home carrier to confirm unlock status before purchasing any travel eSIM plan.

Expert Recommendation
Install your eSIM profile at home, on a reliable Wi-Fi connection, before the day of departure. This ensures you are connected the moment you step off the aircraft — without the inconvenience of airport Wi-Fi dependency.
Chapter IV
Toggle Airplane Mode off and on. Verify Data Roaming is enabled for the eSIM line. Confirm the eSIM is set as the default data source. Allow 2–3 minutes for network registration to complete.
Ensure adequate lighting. Maintain a distance of 15–20 centimetres. If scanning proves impossible, most providers offer a manual activation code as an alternative.
Verify your high-speed data allocation has not been exhausted via your provider's application. Toggle the eSIM off and on to prompt network reselection. Consider relocating to an area with stronger signal coverage.
