What you need before activating an eSIM

A few quick checks can prevent failed installation attempts and save time during setup.

A compatible iPhone, Android phone, tablet, or laptop
A reliable Wi-Fi connection for downloading the eSIM profile
The QR code or manual activation details from your provider

Why your eSIM may not be activating

Most setup issues come from a short list of problems that are easy to check.

Your phone does not support eSIM
Your device is carrier-locked
You are not connected to stable Wi-Fi
The QR code has already been used or scanned incorrectly
The new eSIM was installed but not selected for data

If the QR code scans but data does not work, review your active data line, roaming settings, and whether the eSIM profile is enabled.

If the phone cannot even begin installation, the issue is often compatibility or carrier lock status rather than the QR code itself.
