Less than most people expect. The cheapest Guernsey plan right now is $6.30 for 1 GB for 7 days — plenty if you mostly need maps, WhatsApp and the odd search. Heavy scroller or planning to hotspot your laptop? Go bigger — plans here go up to 20 GB, and topping up later takes about a minute from your account.

For most travellers, honestly, yes. Roaming bundles from home carriers tend to be small, expensive, or both — and the scary part is what happens after the bundle runs out. A prepaid eSIM can't surprise you: you pay once, you know exactly what you get, and your normal SIM stays active for calls and texts. The only time I'd say skip the eSIM is if your home plan genuinely includes Guernsey at no extra cost.

If it were my trip: the 1 GB for 7 days option at $6.30. That covers maps, socials and photo backups for a typical week without babysitting your data balance. Install it on Wi-Fi the night before you fly — it only starts counting when you first connect in Guernsey, so nothing is wasted.
