You'll be invited to install your eSIM as soon as you've bought your travel data. If you don't do it right away then once you open up the jolli app it'll invite you to do it whenever you're ready before travelling.
Install in just one tap:
For both iOS and Android, it’s just one tap from the jolli app.
Once installed all you have to do is head to the country you’ve bought and it’ll activate as soon as you arrive. No messing about. And that’ll happen automatically, so you’ll be connected before they turn off the ‘stay seated’ signs that people ignore.
Head to settings to make sure jolli is the SIM your using for data and turn off data roaming on your home network so you don’t get stung for any nasty bills when you get home. We’re all about the savings!
