The best eSIM for Jersey depends on how much data you need, but for a typical trip eSIM Ahora offers plans from $1.20, activated by QR code in about 30 seconds with no roaming from your home carrier. A 3 GB, 30-day plan costs $4.50. You connect, with top-ups available and nationwide coverage. Compatible with iPhone XS or newer, Samsung Galaxy S21+ and Google Pixel 3+.

Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Jersey eSIM runs on one network: JT. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick JT by hand.
