Run through the four quick checks first if this is your first eSIM.
1
Open your eSIM on your phone
In Chrome (or Samsung Internet) on the phone you’ll travel with, sign in at onroamly.com/my-esims and tap your eSIM.
2
Tap Add to Android
Under Install your eSIM, tap Add to Android (one-touch install on this device).
3
Tap Setup
Android asks to set up your eSIM, and says some device information will be shared with Google and the network to do it. That’s normal. Tap Setup (some phones say Download, Add or Next).
4
Follow the prompts
Name the SIM something you’ll recognise, like Roamly or the country you’re visiting, and keep your normal SIM for calls and messages if asked. Roamly is data-only.
5
Leave the Roamly SIM off until you land
When Android confirms the eSIM is installed, open Settings → Network and internet → SIMs (Samsung: Settings → Connections → SIM manager), tap the Roamly SIM and make sure Use this SIM is off. The plan won’t start until you turn it on and connect at your destination.
6
Turn off Roaming on your normal SIM
While you’re still at home: on the same SIMs screen, tap your normal SIM and turn Roaming off (Samsung: Settings → Connections → Mobile networks → Data roaming). That’s the switch that stops your home carrier charging you overseas. If you won’t need calls or texts on your number while you’re away, you can turn Use this SIM off for that SIM instead; it comes back exactly as it was when you switch it on at home.
Back on the website your eSIM’s status changes to Installed within a minute or so.
On a computer?
Add to Android only works on the phone itself, because it opens that phone’s settings. If you’re on a computer the website will say so and offer the QR code instead: leave it on screen and scan it with the phone. See Install with a QR code or manual setup.When you land
Three switches get you online: turn the Roamly line on, select it for mobile data, and turn on Data Roaming for that line only. Follow Just landed? How to activate your eSIM.Something not working?
- No Add to Android button? Your eSIM is still being set up — usually under five minutes. See I paid but can’t see my eSIM.
- Tapping the button did nothing? A few phones don’t support one-touch setup. Tap Manual setup instead and follow the manual steps.
- Android showed an error? See My eSIM won’t install.
