To install an eSIM with a QR code, connect your phone to Wi-Fi, open your cellular or mobile network settings, choose Add eSIM or Add mobile plan, scan the provider QR code, follow the prompts, label the line, and save the QR email until your trip is complete.
For travel, install the eSIM before departure while you have a stable connection. Activate the travel data line when you arrive, or follow the exact activation timing in your provider instructions. With ZenRoam, travelers receive instant QR delivery for prepaid 4G/5G LTE travel data, free hotspot where supported, and no contract.
What is an eSIM QR code?
An eSIM QR code is a setup code from your eSIM provider. Your phone scans it to download the eSIM profile, which adds a new mobile line to your device settings.
For travel eSIMs, the QR code usually arrives by email after checkout. Some providers also offer a setup link, app-based setup, or manual details such as an activation code. The QR code is the most common path because it is easy to scan and does not require typing long technical details.
If you want a broader explainer first, read what an eSIM is and how it works. This guide focuses on the QR code setup flow.
Before you scan the QR code
A few checks can prevent most setup issues. Do these before you start:
- Check eSIM compatibility: Your phone must support eSIM and be carrier-unlocked for third-party travel eSIMs.
- Connect to Wi-Fi: Your phone needs an internet connection to download the eSIM profile.
- Open the QR code on another screen: Use a laptop, tablet, second phone, or printed copy if your phone needs to scan it with the camera.
- Keep your QR email: Save the QR code, manual setup details, order number, and support contact.
- Read activation timing: Some plans start when installed, while others start when they connect to a supported destination network.
- Keep your primary SIM active: If your phone supports dual SIM, your original number can stay available while the eSIM handles travel data.
How to install an eSIM with a QR code
- Buy your eSIM plan: Choose a destination or region, pick your data and validity, then complete checkout.
- Open the QR code email: Display the QR code on another screen or print it.
- Connect your phone to Wi-Fi: Use a stable home, hotel, or airport connection.
- Open eSIM settings: Go to the cellular, mobile data, or network settings on your phone.
- Choose the add eSIM option: Look for Add eSIM, Add mobile plan, Add SIM, or a similar option.
- Scan the QR code: Point your phone camera at the provider QR code and follow the on-screen prompts.
- Enter any confirmation code: If your provider gives a confirmation code, enter it exactly as shown.
- Label the eSIM line: Use a clear label such as Travel, ZenRoam, or your destination name.
- Choose your default lines: Keep your primary SIM for calls and texts if you want your original number available. Set mobile data to the travel eSIM when your trip starts.
- Save your setup details: Keep the QR email until your trip is complete.
If you still need to buy a plan, this checklist pairs well with the guide to buy your first eSIM before a trip.

What if the QR code is on the same phone?
This is a common travel setup problem. Your phone camera may need to scan the QR code, so opening the QR code on the same screen can be awkward.
Use one of these options:
- Open the QR code email on a laptop, tablet, or another phone.
- Print the QR code before your trip.
- Use a setup link if your provider includes one.
- Use manual setup details if your provider includes an activation code or SM-DP+ address.
- On supported iPhone versions, tap and hold a QR code in a compatible email or browser flow if your device offers an Add eSIM option.
Keep the email after installation. Some eSIM QR codes can be used only once, and support teams may ask for your order details if you need help.
Install vs activate: what is the difference?
Installing an eSIM adds the eSIM profile to your phone. Activating it starts or connects the plan, depending on the provider and plan rules.
For travel, the safest habit is to install the eSIM before departure on Wi-Fi, then turn on the travel eSIM line and data roaming when you arrive if your setup instructions say to do that. Some plans may start their validity when installed, so always read the activation policy that comes with your QR code.
ZenRoam plans are designed for travel preparation: choose a plan, receive your QR code by email, install before departure, and activate according to the instructions when you arrive.
eSIM QR code troubleshooting
| Problem | Likely cause | What to try |
|---|---|---|
| QR code will not scan | Screen glare, low brightness, damaged printout, camera focus issue | Increase screen brightness, clean the camera, open the code on a larger screen, or use manual details if provided. |
| QR code is on the same phone | The phone camera cannot easily scan its own screen | Open the QR email on another device, print it, use a setup link, or use manual entry. |
| No Add eSIM option appears | Phone may not support eSIM, software may be outdated, or device may be carrier locked | Check device compatibility, update software, and confirm your phone is unlocked. |
| Phone asks for a confirmation code | Provider requires an extra activation code | Check the QR email and enter the confirmation code exactly as provided. |
| eSIM installed but no data | Wrong data line, data roaming off, plan not active yet, or unsupported location | Select the eSIM for mobile data, turn on data roaming if instructed, restart the phone, and check you are in the covered destination. |
| QR code says it was already used | Many eSIM QR codes are single-use | Do not delete the eSIM during troubleshooting. Contact the provider with your order details. |
| Setup fails on airport Wi-Fi | Captive portal, weak connection, or blocked network | Complete Wi-Fi login first, move closer to the router, use a different Wi-Fi network, or install before leaving home. |

FAQ
How do I get a QR code for an eSIM?
Buy an eSIM plan from a provider that supports your destination and device. After checkout, the provider usually sends the QR code by email or shows it in your account or app. ZenRoam sends setup details by email after purchase.
Can I install an eSIM if the QR code is on the same phone?
Yes. Open the QR code on another device, print it, use a setup link if provided, or enter manual setup details if your provider includes them.
Do I need Wi-Fi to install an eSIM QR code?
Most travelers should use Wi-Fi. Your phone needs an internet connection to download the eSIM profile. A stable home or hotel Wi-Fi connection is usually better than trying to install after landing.
Can I scan the same eSIM QR code twice?
Many eSIM QR codes are single-use. After the eSIM installs, avoid deleting it during your trip unless your provider tells you to. Contact support if you need to reinstall or transfer a plan.
Why is my eSIM QR code not working?
Common causes include poor Wi-Fi, screen glare, an incompatible phone, a carrier-locked device, an already-used QR code, or entering the wrong confirmation code. Start with Wi-Fi, compatibility, and camera focus checks.
Should I install the eSIM before or after my flight?
Install it before departure if your plan instructions allow pre-trip installation. This gives you time to fix setup issues on stable Wi-Fi. Activate or use the travel data line according to your provider instructions.
Is installing an eSIM the same as activating it?
Installing adds the eSIM profile to your phone. Activating starts or connects the plan based on the plan rules. Some plans start when installed, while others start when they connect to a supported network.
Can I keep my original number after installing a travel eSIM?
Yes, if your phone supports dual SIM and your primary SIM remains active. Many travelers keep their original SIM for calls and texts while using the travel eSIM for mobile data.
Does hotspot work after QR code installation?
Hotspot depends on the plan, device, and local network. ZenRoam includes free hotspot where supported, so check your plan details before relying on hotspot for a laptop or travel companion.
What should I save before I travel?
Save your QR code email, manual setup details, order number, activation instructions, and support contact. Keep them until your trip is complete.
