根西岛位于圣马洛湾,靠近诺曼底而非英格兰,既不属于英国也不属于欧盟 — 因此如果您的电话套餐仅在其中一方有效,它可能在您下船的那一刻就停止。请在出航前安装 eSIM,圣彼得港会以可用的地图迎接您。


从 Saint‑Malo、Jersey、Poole 和 Portsmouth 有轮渡抵达 St Peter Port,并有来自诺曼底海岸的小型夏季船只;航班在距市区十分钟车程处降落。从码头出发,一切——公交总站、前往 Herm 和 Sark 的船只、维克多·雨果的故居——都在步行范围内,前提是您知道往哪个方向走。

Guernsey 大约二十五平方英里,网络覆盖几乎整个岛屿:St Peter Port、St Sampson、机场和西海岸的海湾有强劲的4G,较繁忙的地带有5G。
在地面下落的地方信号变弱——在南海岸的悬崖小径及其下方的海湾,岩石挡住了杆塔——以及在较小的岛屿上,那里一切本就少。出悬崖步道前请保存地图。

根西岛是一个 Crown Dependency,拥有自己的政府、自己的英镑和自己的移动网络。欧盟的 roam-like-at-home 规则并未覆盖到这里,所以法国或德国的套餐可能将根西岛计为单独目的地;英国的套餐也通过漫游覆盖到那里,且有些会收费。运营商各不相同 — 只有价格表知道。
旅行用 eSIM 可以事先解决:一个固定价格,使用当地网络。
这里海水涨落可达十米。通道 — 比如通往 Lihou Island 的那条 — 仅在退潮时开放并迅速关闭。沿海步行前请查看潮汐表。
On the coasts that face France, a home SIM with roaming on may pick up a French mast instead of a local one — and bill accordingly. Turn data roaming off on the home line and on only for the travel eSIM.
No. Guernsey is outside the European Union, and EU roaming rules do not apply. Some European operators include the Channel Islands in their Europe zone, others bill them separately — check your price list, or use a travel eSIM.
It depends on the operator. Guernsey's networks are separate from the British ones, so a UK plan reaches them by roaming: several operators include the Channel Islands, others charge.
The network reaches the other islands of the Bailiwick, but more thinly than Guernsey itself — expect good signal near the harbours and gaps elsewhere.
No — Jersey is a separate destination with its own plans. For a trip that also takes in France or England, a regional Europe plan is simpler.
Near either coast, yes; in open water, no — for any SIM. The travel eSIM connects as the island's network comes into range, usually before the ship docks.
Pounds. Guernsey issues its own notes, equal in value to British ones, which are accepted everywhere. Cards and phone payments work across the island.
