海岛和偏远的小目的地，网络怎么准备

Not always. The region name is a heading; the binding scope is the plan's list of countries and territories. Many islands and dependencies are treated as separate areas with their own agreements, so search the list by name before every purchase.

For small destinations, arriving already connected usually wins, because SIM outlets can be far away, hours are short and registration rules differ by country. If you are staying weeks, a local SIM may pay off in the long run, but you still want something working for day one.

Treat it as something to test rather than a conclusion. Wi-Fi in small places often shares one incoming connection across the whole building and can slow markedly in the evening. Test the tasks that matter to you on day one and adjust, rather than waiting until the day you truly need it.

As a rule, do not plan around it. Signal usually thins away from shore and can vanish mid-route. Put tickets, maps and destination details on the device before boarding and treat the crossing as offline time.

Start with what is in your hands: confirm data roaming is on for the line carrying the plan, confirm the correct line is set for data if the phone runs two, and toggle airplane mode once to force a fresh attach. If it still fails, verify the destination really is in the plan's list, then contact us with your location and what you are seeing.

Rely on accommodation Wi-Fi, or buy a local SIM on arrival under that country's registration rules. We will not sell a plan by claiming coverage we cannot confirm.

Signal generally falls away from shore. Assume no connection during a sea crossing and prepare everything before boarding.
