背包旅行好几个月，流量该怎么安排

Let your certainty decide. If you know where you will be for the next two months, a longer purchase reduces how often you have to deal with it. If the route can still change, shorter legs are far more forgiving, because a purchase does not move when you change your mind. Most long-trip travellers settle around two to four weeks per leg.

Most phones can store several profiles while only a limited number are active at once, and how many can be stored varies by model and OS. Check the manufacturer's information for your device. In practice, delete only profiles that have genuinely expired, and name each line so you know which country it belongs to — by month three the list gets long enough to confuse.

Refund and change terms are set by the supplier and by the individual plan; there is no single rule. Read the terms before buying, especially while the route is unsettled — which is the main reason to buy only as far as you are sure. If it has already happened, contact support with your order details for an answer specific to your case.

The rules for keeping a number alive while it is idle belong to that operator — both the timeframe and what you must do. Contact your provider before departure and ask plainly what happens after three to six months of no use and how to keep the line in good standing. The answers differ substantially between contract and prepaid, so one cannot be inferred from the other.

If you move together nearly all the time, one person holding the plan and sharing a hotspot is cheaper and simpler — provided that plan permits sharing, and provided you accept that the other person drops offline the moment you separate. If you split up often, one working while the other explores, separate plans pay for themselves in both convenience and safety.

Message LINE @esimonline at https://lin.ee/skDPoNx or email esimonline.asia@gmail.com. Include your phone model and OS version, the country you are in, the network names showing in the list, and a screenshot of the failing screen; that set usually gets a specific answer on the first reply. Anything about your home number — SMS delivery, roaming charges — has to go to the operator that issued that SIM.

Convenient but not always cheapest. Compare against regional plans matched to your legs, and confirm the country list really covers your route.

Use the operating system counter alongside the provider's figure. They rarely match exactly, so plan against the lower one.
