Jersey travel data eSIM
What is a Jersey eSIM?
Jersey is a compact Crown Dependency off the French coast, where getting around without local data can slow down your visit. A Jersey eSIM gives you immediate mobile data upon arrival in Saint Helier or other parts of the island. Install it before you fly so your device is ready to connect the moment you land. This setup ensures you have access to maps, booking apps, and navigation tools from the start of your trip, avoiding the hassle of finding local connectivity options after your journey begins.
Your Jersey eSIM connects to the JT 5G network. The plan activates only when your phone first connects to a local network in Jersey. Validity periods range from seven to thirty days depending on the data amount selected. This structure suits short breaks or longer stays. You manage data usage directly on your device, with no need for physical SIM cards or local top-ups during your time on the island.

Local networks
Which networks you connect to in Jersey
The eSIM connects to the JT 5G operator in Jersey. Coverage availability depends entirely on the JT 5G network presence at your specific location. Urban areas like Saint Helier typically have stronger network infrastructure than remote coastal spots or inland valleys. Because Jersey is a small island, network conditions can vary by street or district. Always check local network maps or ask locals about specific areas if you plan to visit less populated zones.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operator does the Jersey eSIM use?
The eSIM connects to the JT 5G network. This means your data traffic is routed through this specific local provider. It ensures you are using a network established within the Bailiwick of Jersey, aligning with local infrastructure standards for mobile data delivery on the island.
Does the eSIM work in France?
No, this is a single-country plan valid only in Jersey. It does not provide data access in neighboring France. If you plan to visit multiple countries, including the Cotentin Peninsula, consider purchasing a regional plan designed for multi-country travel instead.
Which plan size suits a trip to Saint Helier and Gorey?
As a rough guide, a 3GB or 5GB plan may suffice for a short stay visiting Saint Helier and Gorey. Heavier data usage, such as frequent video streaming or constant map usage, might require the 10GB option. Assess your typical daily data consumption to choose the appropriate tier.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
