Tips for Travelers in Guernsey
Make the most of your Guernsey trip with these connectivity tips from fellow travelers:
Download and install your AloOui Guernsey eSIM profile at home before departure. It won't activate until you land — so you're ready the moment you step off the plane at Guernsey Airport.
Your AloOui eSIM runs alongside your existing SIM. Keep your home number for calls and WhatsApp while using the Guernsey eSIM for data — no need to choose.
Before exploring the coastal cliff paths, the Little Chapel, or the quieter parishes, download offline maps on Google Maps or Maps.me. Guernsey's rural lanes can have patchy signal, so offline maps are a smart backup.
On the Unlimited Lite plan, enable Low Data Mode on your phone to stretch your 1GB daily full-speed quota further — great for sightseeing days with light usage.
Guernsey is a great base for day trips to Herm and Sark. Use your AloOui data to book ferry tickets, check timetables, and navigate — connectivity is key when hopping between the Channel Islands.
Whether you're cycling the island's quiet lanes, visiting the Hauteville House, or enjoying fresh seafood at a harbour-side restaurant, your AloOui eSIM keeps you connected throughout your stay.
For Business Travelers & Digital Nomads
Guernsey is a leading international finance centre with a thriving fintech and professional services sector. Here's why AloOui's Unlimited Plus is the go-to plan for professionals visiting the island.
The Plus plan gives you network priority — so even in busy St. Peter Port business districts or at Guernsey Airport, your connection stays fast and stable.
Video calls, large file uploads, cloud syncing — 2GB of full-speed data per day keeps your workflow uninterrupted, with 2 Mbps fallback for lighter tasks.
Share your connection with your laptop or tablet. Perfect for working from a St. Peter Port café or a hotel without relying on public Wi-Fi.
Extended stays covered. Whether you're on a month-long business engagement or a longer island stay, one plan keeps you connected the whole time.
Scan a QR code and you're online. No SIM procurement, no corporate roaming plans, no waiting at a carrier store. Instant activation means you're productive from day one.
One flat rate, no surprise roaming bills. Ideal for expense reporting and budget-conscious professionals who need reliable data without unpredictable carrier charges.
