Yes! With JamboSim's deferred activation, you can purchase your eSIM weeks or even months before your trip. Simply choose your preferred activation date during checkout - your data plan won't start until that day. This way you can prepare everything in advance and your eSIM will be ready the moment you land in Guernsey.
After purchasing your JamboSim eSIM, you'll receive a QR code via email. Simply scan it with your phone's camera, follow the on-screen prompts to install the eSIM profile, and enable data roaming. Your eSIM will automatically connect to the best local network when you arrive in Guernsey. The whole process takes under 2 minutes.
