Travel eSIM QR Code Not Working — How to Fix It Quickly (NexaEsim)

Travel eSIM QR code not working fix: follow these fast steps to install or recover your NexaEsim profile and get online while traveling.

Quick Answer

If your travel eSIM QR code won’t install, first restart the phone, toggle Airplane Mode on and off, and try scanning again. If that fails, confirm the device is eSIM‑capable and carrier‑unlocked, verify the QR wasn’t already used or expired, and try manual installation using the SM‑DP+ address and activation code. If the QR is single‑use or expired, contact NexaEsim support with your order number, device model, OS version, and a screenshot of the error for a replacement.

Quick fixes (2–3 minute checklist)

Restart, toggle Airplane Mode, and retry scanning

Power off/on, or toggle Airplane Mode for 10 seconds, then open the camera and scan the QR again. Small OS glitches often clear with a restart.

Ensure device supports eSIM and is unlocked

Check if your model supports eSIM and that it's not carrier-locked. See NexaEsim's compatible devices page for details: https://nexaesim.com/compatible-devices

Check for one-time or expired QR — was it already used?

Many eSIM QRs are single‑use and may expire after activation or a set time. If you already installed a profile, you may need to remove it before reinstalling, or request a reissue.

Try manual installation (SM‑DP+ and Activation Code)

If scanning fails, use manual install: open Settings > Add Cellular Plan > Enter SM‑DP+ address and Activation Code supplied in your NexaEsim email. Example format (fake values): SM‑DP+ 'esim.nexae.example.com' Activation Code 'AB12‑CD34‑EF56'.

Error messages & what they mean

Step-by-step fixes by OS

iPhone (iOS)

1. Open Camera, point at the QR. Tap the notification to add cellular plan.
2. Or go to Settings > Cellular (Mobile Data) > Add Cellular Plan and scan the QR.
3. If scanning fails, choose Enter Details Manually and add SM‑DP+ and Activation Code.
4. After install: Settings > Cellular > your eSIM > Enable Data Roaming if traveling.
5. If you see 'This code is no longer valid', remove any duplicate profile and contact support.

Android (Pixel, Samsung, others)

1. Open Settings > Network & internet > Mobile network > Add carrier or Add eSIM.
2. Scan QR or choose manual add to paste SM‑DP+ and Activation Code.
3. On Samsung, use Settings > Connections > SIM card manager > Add mobile plan.
4. If QR directs to a link, open it in the same device's browser and follow the prompt to install.

Manual install using SM‑DP+ and Activation Code

Formatting matters: SM‑DP+ looks like a URL (no protocol required). Activation Code is usually alphanumeric with dashes. Example (fake): SM‑DP+ 'esim.nexae.example.com' Activation Code 'AB12‑CD34‑EF56'. Copy exactly as provided in your NexaEsim email.

Camera & QR file troubleshooting (scanning problems)

Image quality, cropping, contrast, print vs screen

• Ensure the QR is not zoomed/cropped. Show the whole code in the frame.
• Increase screen brightness or print the QR at high contrast.
• Remove screen protectors or fingerprints that may obscure the code.

Try another device to scan / open link on same device

Scan the QR with a second phone to get the link, then email the activation link to the target device or open it in the same phone's browser.

Network & phone settings to check

Carrier lock check and how to confirm

Use Settings or contact your original carrier to confirm the phone is unlocked for eSIM use. Some carrier-locked phones block third-party eSIM profiles.

Reset network settings, OS updates, SIM profile deletion caveats

• Try Settings > General > Transfer or Reset > Reset > Reset Network Settings (iOS) or similar on Android.
• Update iOS/Android to the latest stable release before trying again.
• When deleting profiles, note that single-use QRs may not be reusable after a deletion.

APN settings & turning on Data Roaming

If installed but no data, check APN values in your plan info and enable Data Roaming while abroad.
