在国外待超过一个月：哪种上网方式撑得住
旅行套餐是为短途设计的，长住得换一套算法来想。
快速解答
- Past about thirty days, renewing travel plans repeatedly usually costs more than a local monthly SIM.
- But local SIMs in many countries need document registration, which takes time and sometimes an address.
- The middle path is a travel eSIM for week one, then a local plan once the paperwork is done.

常见问题
For three months, is one long plan better than three monthly ones?+
It depends on the validities actually offered and on whether you will stay in one country throughout. A single plan reduces admin and the chance of a gap; buying month by month lets you resize once you know your real first-month figure. If your three months are not certain, buying in stages is usually the lower risk.
If a plan expires abroad, can I buy another with no connection?+
Buying needs a connection, which is exactly why the next plan should be bought before the current one ends. If it does happen, find Wi-Fi at your accommodation, a restaurant or an airport and do it from there. Keeping an offline screenshot of your order number and our contact details helps a great deal here.
Is there a problem with using a roaming plan continuously for months?+
Travel plans are designed for travel, and sustained use in one place over months can conflict with the fair-use terms of the supplier behind the plan. The details differ per plan, so read the terms of the one you intend to buy, or ask us first if you plan to run it for months.
Should I keep my home line in the phone as well?+
It helps if you still receive verification messages on that number, which is the most common reason. The usual arrangement is to keep the home line active with its data switched off, so all data runs over the eSIM. Charging terms for that line belong to your home operator, so confirm them before travelling.
Does the phone need to run two lines at once?+
Not if you will use data from one plan and are not waiting on messages to your old number. If you want both at the same time, the handset has to support two active lines, and that capability differs by model and OS version, so check your own device before planning around it.
Buy before flying, or wait until arrival?+
Installing before you fly means being online on landing, which is worth a lot on a first day of onward travel and messages to a host. Waiting gives you more in-country options but accepts a period offline after arrival. Many people install a short plan before flying and decide the long-term question once they are there.

Is renewing different from buying a new plan?+
Topping up keeps the same profile so nothing is reinstalled; a new plan means installing again. Price per GB can differ, so compare both.
Can a travel eSIM cover a work visa stay?+
Technically yes at the start, but some agencies want a local number for contact, so plan for a local SIM as well.
