出差上网：会议不掉线，费用也报得掉

For work travel, some headroom usually pays for itself, because the time lost to topping up mid-trip costs more than the price difference. That does not mean buying wildly over: size it from the meeting hours in the calendar, then add margin for travel days, when schedules slip. If you do not know your own consumption, open the data usage history in your phone's settings — those are your numbers, and they beat any general average.

Two layers work. The first is Wi-Fi you have actually tested in that building, not Wi-Fi you assume will be fine. The second is a way into the meeting that does not depend on your data at all: a dial-in number saved in advance, or an agreement with a colleague that if you vanish for more than two minutes they carry on without you. Rehearsing that agreement is worth more than any extra hardware.

Usually yes, but read the terms of the plan you bought, because some restrict sharing, particularly plans marketed as unlimited. Alongside that, mark the connection as metered on the laptop and defer system updates: left on its defaults, a laptop can consume substantially more than a phone.

Only if that country is on the plan's covered list. A single-country plan will not work at a transit airport, and that is the single most common reason people think the product has failed. If your route has a long layover or a meeting in between, look at a regional plan that covers the whole path, and check the country list against the actual itinerary before buying.

It can be requested, but it is rarely a one-line edit: an accounting document that has already been issued has to be cancelled and reissued, which takes considerably longer than entering the details correctly at checkout. If it has already happened, contact us with the order number, the registered company name and the tax number via LINE at https://lin.ee/skDPoNx or email esimonline.asia@gmail.com, and we can tell you what is possible in that case.

Reach us on LINE at https://lin.ee/skDPoNx or by email at esimonline.asia@gmail.com. We do not run a phone line and we are not staffed around the clock, so plan on the assumption that a reply is not instant. What helps most is a complete first message: order number, phone model, the country you are in, and a screenshot of the network status, so we can rule causes out quickly.

Yes. Enter the company name and tax number at checkout; adding them later can mean reissuing the whole document.

Yes, through the business page, which handles bulk orders and a single billing cycle.
