Troubleshooting

⚠️ QR code not working
Make sure you are connected to Wi-Fi. Try the manual entry method with the SM-DP+ address and activation code from your email.
⚠️ No "Add eSIM" option in settings
Your device may not support eSIM, or it may be carrier-locked. Check our device compatibility guide or contact your phone manufacturer.
⚠️ "eSIM already downloaded" error
Each eSIM profile can only be installed on one device. If you previously installed it and it is missing, contact Siima support.
⚠️ eSIM installed but no signal
Make sure the eSIM is set as your active data line. Go to Settings → Cellular → Cellular Data and select your travel eSIM. Also check you are in a covered area.

Frequently asked questions

Do I need Wi-Fi to install an eSIM?
Yes. You need an active internet connection (Wi-Fi or existing mobile data) to download the eSIM profile. Once installed, it works without Wi-Fi.
Can I install the eSIM before my trip?
Yes, and we recommend it. Install at home on Wi-Fi, then enable the eSIM when you land. Your data plan starts when you first use mobile data.
Can I transfer an eSIM to a new phone?
No. Once installed, an eSIM profile is tied to that device. You will need a new plan for a new phone.
What if the QR code does not work?
Use manual entry: Settings → Cellular → Add eSIM → Enter details manually. Copy the SM-DP+ address and activation code from your email.
