Activating O2 eSIM on Android
Check your device specs — not all Android models support eSIM. iPhones from XR onwards, Samsung Galaxy from S20 onwards, and Google Pixel from Pixel 3 onwards support eSIM.
A carrier-locked Android will reject O2 eSIM. To check: go to Settings → Network & Internet → Mobile Network → Advanced → Access Point Names. If you see a carrier lock message, contact your current provider to unlock.
eSIM QR codes expire after 24–72 hours. If the code was emailed more than 3 days ago, contact O2 on 202 (free from O2) to get a new activation link.
Turn off mobile data and Wi-Fi (use only the activation download). Scan the QR code using Settings → Network & Internet → Mobile Network → Advanced → Access Point Names on your Android. Ensure the code is fully visible — partial scans fail silently.
Complete activation via: My O2 app → Account → Manage SIM → Set up eSIM. Follow every on-screen prompt without skipping steps. Carrier provisioning can take 10–15 minutes.
After activation completes, restart your Android and wait up to 30 minutes for O2 to fully provision the eSIM profile. Data and calls should activate automatically.
If the eSIM shows as installed but has no service after 30 minutes, call O2 on 202 (free from O2). The provisioning record may need resetting on O2's system.

Frequently Asked Questions
Is my Android compatible with O2 eSIM?
To use O2 eSIM on your Android, the device must be eSIM-compatible and unlocked. iPhones from XR onwards, Samsung Galaxy from S20 onwards, and Pixel from Pixel 3a support eSIM. Confirm compatibility at the O2 eSIM information page or call 202 (free from O2).
How long does O2 eSIM activation take?
Most O2 eSIM activations complete within 15 minutes. In some cases, provisioning can take up to 2 hours. If your eSIM shows as installed but has no service after 2 hours, restart your Android and contact O2 on 202 (free from O2) to trigger a manual provisioning refresh.
Can I have both eSIM and physical SIM on O2?
Yes, if your Android supports Dual SIM — most modern flagships do. You can run a O2 eSIM alongside a physical SIM from another carrier, or use the O2 eSIM as your primary and keep a travel SIM as secondary.
