流量计算器
你到底需要多少流量？
老实说，答案是“比你以为的少”。地图和聊天几乎不占流量，真正吃流量的是视频。在下面填一下行程，我们给个建议，并把账算给你看。
我们建议
5 GB
按日常使用、每天约 500 MB 算，7 天行程向上取整到 5 GB。
大约相当于 7 小时视频，外加全程的地图和聊天。想留点余量？往上选一档。
估算偏保守，而且是向上取整的，所以基本不会不够用。实际用量取决于你用什么应用、看什么画质；大件下载和追剧放到 Wi-Fi 上，任何套餐都能撑更久。
About this calculator
Where do the plan prices come from?
From the catalogue for the destination you pick, the same prices as that destination page. This page does not store a price of its own.
How is the GB number chosen?
From the trip length and the style you select. The result shows the MB per day used in the sum, then rounds up to a plan size.
What if I use more than the estimate?
Pick the next size up. Video is what moves the total. The table above shows typical use per hour.
Why is there no price until I pick a destination?
A price belongs to a destination. Pick one and the matching sizes appear with their catalogue price and the price per GB.
Where do I buy the plan?
Open the destination page linked under the list. Checkout is on that page, and the price there is the one you pay.
