Beijing Unicom and Just My Socks: Which Plan Should You Try First?北京联通买 Just My Socks：先试哪个套餐？
For Beijing Unicom, the first question is not LA or HK in the abstract. It is whether you mainly need AI tools, US websites, low-latency browsing or a Japan-facing fallback.北京联通先别抽象争 LA 还是 HK。先问自己主要是 AI 工具、美国网站、低延迟浏览，还是需要日本方向备用。

How to use this Beijing Unicom page这篇北京联通页面该怎么用
I would not treat Beijing Unicom as a one-node answer. If your main use is ChatGPT, Claude, Gemini or US websites, start with LA 500. If the pain point is page response during evening browsing, compare HK CMI+NTT 500 before buying a larger LA package.北京联通不适合用一个节点一刀切。如果主要用 ChatGPT、Claude、Gemini 或美国网站，先看 LA 500；如果痛点是晚高峰网页响应慢，再把 HK CMI+NTT 500 放到前面比较。
For Beijing Unicom, start with LA 500 for AI tools and US services. Choose HK CMI+NTT 500 when regional browsing response is the priority, and keep Tokyo 100 for Japan-specific use.北京联通使用 AI 工具和美国服务先选 LA 500；更重视区域浏览响应时选 HK CMI+NTT 500；日本相关服务再选 Tokyo 100。
Practical recommendation实际购买建议
For Beijing Unicom, I would start from the service you care about, not from the nearest map location. AI tools and US accounts point to LA first; normal browsing lag is where HK deserves the first comparison.北京联通先别按地图距离选，先按你最在意的服务选。AI 工具、美国账号环境先看 LA；日常网页响应慢，再把 HK 放到第一对照位。
Choose LA 500 for AI tools and US accounts, or HK CMI+NTT 500 for regional browsing. Upgrade only when you need more than 500 GB each month.AI 工具和美国账号选 LA 500，区域浏览选 HK CMI+NTT 500；每月需要超过 500 GB 流量时再升级。
Where I would start先从哪个入口看
For Beijing Unicom, choose LA 500 for AI and US services; choose HK CMI+NTT 500 for regional browsing.北京联通使用 AI 和美国服务选 LA 500；区域浏览选 HK CMI+NTT 500。

The buying order I would use我会按这个顺序下手
If the purchase is mainly for AI tools, I would not over-optimize for the nearest region first. Many AI and account systems behave more predictably from a US route, so LA 500 is the cleanest first checkout to inspect.如果购买主要是为了 AI 工具，我不会先纠结离北京最近的区域。很多 AI 和账号系统更偏美国路线，LA 500 是最干净的第一个结账入口。
If daily browsing is the priority, choose HK CMI+NTT 500 before upgrading to a larger LA plan. Keep LA 500 as the better fit for AI tools and US accounts.如果主要是日常网页，且问题多出现在晚上，先选 HK CMI+NTT 500；AI 工具和美国账号继续选 LA 500。
What to check before and after payment付款前后该看什么
The order summary combines the selected plan, discounted total and billing cycle. Use it to finish the purchase in one pass.订单摘要会集中显示所选套餐、折后总价和账期，可在同一处完成购买。
After purchase, use the apps that matter to you during the evening peak. For Beijing Unicom, this quickly shows whether LA or HK better fits the daily workload.购买后在晚高峰直接使用最重要的 App，这能快速判断北京联通更适合 LA 还是 HK。
Once the primary route is clear, compare it against the current plan comparison.选定主线路后，再对照当前套餐对比。

FAQ常见问题
Does Just My Socks work in Beijing?Just My Socks 在北京能用吗？
Yes, but do not choose only by distance. Decide by the service you care about first: AI and US sites point to LA; latency-sensitive browsing is where HK deserves a comparison.可以，但不要只按距离选。先看你最在意的服务：AI 和美国网站优先 LA；日常浏览怕延迟时再把 HK 放进对比。
Which node is better for Beijing Unicom?北京联通选哪个节点？
LA 500 is the cleaner first click for most AI-tool users. HK CMI+NTT 500 is the first backup when the problem is regional responsiveness rather than US service matching.多数 AI 工具用户先点 LA 500 更顺。问题如果是区域响应，而不是美国服务适配，再优先看 HK CMI+NTT 500。

Choose HK for nearby regional services and LA for US-heavy products. Match the region to the app you open most often.附近区域服务选 HK，偏美国的账号和产品选 LA；按最常打开的应用匹配地区。

Start with LA 500. If it is out of stock or the checkout price is not what you expected, then compare LA 1000 before jumping to another region.先看 LA 500。如果缺货或结账价格不合适，再比较 LA 1000，不要一开始就跳到其他区域。
