Why does the QR code fail when I scan it again?

Most eSIM QR codes are for one installation. Check your Cellular, SIM manager, or SIMs screen—the profile may already be installed. If it is there, do not rescan or delete it; turn it on at the destination.

Should I delete the eSIM if it is not connecting?

No. Do not delete it while troubleshooting. A deleted eSIM may not be installable again. Check the data line, roaming, APN, network selection, airplane mode, and restart first.

Can I install the same eSIM on another phone?

No. A travel eSIM is generally tied to the first device where it is installed and cannot be moved by scanning the QR again.

Will my normal phone number still work?

Yes, if your phone supports dual SIM and your primary line remains enabled. To prevent roaming charges, keep VoyeSim selected for mobile data and cellular data switching off.

Watch the VoyeSim walkthrough made for your phone. Every tap, settings screen, arrival step, and common QR-code error is shown visually.

BEFORE YOU START

Four checks prevent most installation problems

✓

Compatible phone

Confirm that your exact phone model supports eSIM.

Check your device →

✓

Carrier unlocked

A carrier-locked phone may block travel eSIM installation.

✓

Stable internet

Use reliable Wi-Fi during installation and temporarily disable VPN.

✓

QR on another screen

Open the QR on a laptop or second device, or use manual details.

🔒

Keep the QR code private. It is a secure activation credential for one device. Do not publish or forward it.

STEP-BY-STEP

Choose your device

Menu names can differ slightly by phone model and software version.

⌨

Cannot scan the QR code?

Choose the manual-entry option and copy the SM-DP+ address and activation code shown with your VoyeSim order. Enter them exactly as provided.

WHEN YOU ARRIVE

Installed does not always mean connected—yet

Your eSIM can be installed before travel. It connects only when you are inside the plan's coverage area and the correct mobile-data settings are enabled.

Plan validity: Most plans begin when the eSIM first connects to a supported network, unless the plan details say otherwise.

Open SIM/eSIM settings and switch the VoyeSim line on.

Choose VoyeSim as the phone’s mobile-data SIM.

Enable data roaming for the VoyeSim line only.

Keep cellular data switching off to avoid unexpected home-carrier data use.

Wait a few minutes. If needed, toggle airplane mode or restart the phone.

TROUBLESHOOTING

Fix the problem without deleting your eSIM

Start with the message you see. Deleting an installed eSIM can make it impossible to reinstall.

MOST COMMON

“Code is no longer valid” or “already used”

This often means the eSIM has already been added.

Open Settings → Cellular/Mobile Data on iPhone, or Settings → SIM manager/SIMs on Android.
Look for a new line, travel eSIM, or the label you chose during setup.
If it is present, turn the line on when you reach the destination. Do not scan again.
If no profile exists and this was the first attempt, use stable Wi-Fi, turn off VPN, restart, and try manual installation.

Do not delete the profile while troubleshooting.

Unable to activate or stuck activating

The profile may still be installed.

Check SIM/eSIM settings before trying again.
Use stable Wi-Fi, disable VPN, and restart the phone.
Update the phone software and confirm that the device is carrier-unlocked.
If you are outside the coverage area, final network connection may wait until arrival.

⌁

Installed but no internet

Usually a data-line or network setting.

Confirm VoyeSim is on and selected for mobile data.
Enable data roaming on the VoyeSim line.
Apply the APN shown in your order, if one is provided.
Try automatic network selection, then a supported network manually.
Temporarily select 4G/LTE, toggle airplane mode, and restart.

⌕

QR code will not scan

Use the phone’s eSIM menu—not the Camera app.

Increase screen brightness and avoid glare.
Open the QR on another device or computer.
Use the manual SM-DP+ address and activation code.
If the QR was already scanned, check whether the profile is installed.

No Add eSIM option

Compatibility or carrier lock may be the cause.

Confirm the exact model and country variant supports eSIM.
Dial *#06# and check whether an EID is shown.
Ask the original carrier whether the phone is network-unlocked.
Some employer-managed devices block eSIM changes.

60-SECOND CONNECTION CHECK

Installed, but no mobile data?

Work through these six checks in order. They solve most connection issues at the destination.

1Confirm you are inside the covered destination
2Turn the VoyeSim line on
3Select VoyeSim for mobile data
4Enable data roaming for VoyeSim
5Check APN and network selection in your order
6Toggle airplane mode, then restart the phone

QUICK ANSWERS

Installation questions

Yes. Installing before departure is recommended while you have reliable Wi-Fi. Keep your normal SIM selected for data, then turn on and select VoyeSim when you arrive. Most plans start on first supported-network connection unless the plan says otherwise.
