How to install your e-SIM
Step-by-step e-SIM installation for iPhone and Android — add your plan with a QR code and be online in minutes.
Install it before you fly, turn it on when you land.
- Open Settings and tap "Cellular" (or "Mobile Service").
- Tap "Add eSIM", then choose "Use QR Code".
- Scan the QR code from your delivery email or your account page.
- Give the new line a label, for example "Adonis Travel".
- Keep your main SIM for calls, and select the Adonis e-SIM for Cellular Data.
- When you arrive, switch on Data Roaming for the Adonis line.
- Open Settings, then "Network & internet", then "SIMs".
- Tap "Add eSIM" (on some phones: "Download a SIM instead?").
- Scan the QR code from your delivery email or your account page.
- Confirm the download and activate the new line.
- Set the Adonis e-SIM as your mobile data SIM.
- When you arrive, switch on Data Roaming for the Adonis line.
The QR code can only be scanned once. If anything goes wrong, contact support instead of deleting the e-SIM.
If something is not working
“Incorrect QR code” or the code will not scan
Use manual entry instead: copy the SM-DP+ address and the activation code from your e-SIM page. They are exactly what the QR code contains. Make sure you scan from the phone’s Settings (Add eSIM), not from the camera app or a QR scanner app.
“Unable to add cellular plan” / “This code is no longer valid”
Usually the Wi-Fi dropped mid-download, or the phone is locked to a carrier. Reconnect to stable Wi-Fi and try once more. If it says the code was already used, the e-SIM may already be on the phone — check Settings → Cellular before trying again, and contact us if it is not there.
Installed, but no signal after landing
Check in this order: the travel line is turned on, Data Roaming is on for it, and it is selected for mobile data. Then restart the phone. Still nothing? Settings → Cellular → the travel line → Network Selection: turn Automatic off, wait for the list and pick another network.
Mobile data works, but it is slow
Try another network under Network Selection, and check you have data left on the usage page of your e-SIM.
Can I move it to another phone, or reinstall it?
An e-SIM installs once. Do not delete it to “try again”: contact us and we will check whether it can be reissued.
Will I still get calls and SMS on my own number?
Yes. Keep your main SIM on for calls and SMS and use the travel e-SIM for data only. Roaming charges from your home operator may still apply to calls — WhatsApp and FaceTime calls go over the travel data.
