Compare selectable plans

Standard Guernsey Unlimited options are Lite. Daily high-speed allowances refresh each day. Unlimited does not mean unrestricted high-speed data. Fixed plans end when their allowance or validity runs out, whichever comes first, without reduced-speed continuation. Actual speeds depend on available connectivity. No Premium or Platinum variant is currently selectable on this product. Plus is not Premium.

Guernsey and Jersey coverage

The Guernsey entry lists Sure up to 4G and JT up to 5G. The separate Jersey entry lists JT up to 5G. Connection and speeds depend on your device, supported partner and local conditions; 5G at every location is not guaranteed.

Do not infer coverage in mainland UK, France, Sark, Alderney, Herm or other smaller islands from the product name or ferry route. The provider list names Guernsey and Jersey, but does not individually confirm those other destinations.

Coastal walks and ferry crossings

Save ferry tickets, accommodation details and walking maps offline before leaving reliable coverage. Reception can vary between rural parishes, coastal paths and offshore routes. Continuous service during a ferry crossing is not guaranteed. Check with support before purchasing if connectivity on a particular smaller island is essential. Satellite and maritime networks are not included.

Hotspot and keeping your existing number

Hotspot sharing is available where supported by your device and network, using the same total or daily allowance. This eSIM does not include a local phone number, native calls or SMS. Internet-based messaging and calling depend on connectivity and app availability.

You can keep your home SIM for calls or SMS if your device supports the arrangement. Check its roaming charges, turn off its data roaming and avoid automatic data switching.

Compatibility, installation and activation

Check that your exact device model and regional version support eSIM and are carrier-unlocked. Install the emailed QR code over stable Wi-Fi using Add eSIM in your cellular or SIM settings.

Validity starts when the eSIM activates by connecting to a supported network in a covered destination. Installation alone does not start validity. Connecting in either listed destination, Guernsey or Jersey, can start the plan; it does not reset when you move between them.

When ready, enable AloOui, select it for mobile data and turn on data roaming for that line.

APN and troubleshooting

1. Check that AloOui is enabled, selected for mobile data and has data roaming on.
2. If an APN is required, set it to data.esim, leaving username and password blank. Save/select it; some devices configure this automatically.
3. Toggle airplane mode or restart your phone.
4. Start with automatic network selection; if needed, select a listed supported partner for your destination and move to a stronger-signal area.
5. Check remaining data and validity. Do not delete the eSIM while troubleshooting; contact support first.

For installation assistance or connection problems, contact the AloOui Help Center.

Continuing to mainland UK or France?

Use Shop with AI to compare separate options for your full itinerary. Do not assume a UK or Europe label includes Guernsey and Jersey; verify every destination in the exact product's coverage list before purchasing.
