Jaka jest różnica między danymi lokalnymi a roamingiem globalnym?

In today's highly connected world, mobile data has become an indispensable part of daily life and work. Whether for personal travel or application in IoT smart devices, the concepts of local data and global data have gradually entered public view. There are significant differences between the two in multiple aspects, and understanding these differences can help us choose and use data services more rationally.

``` msgid "Local data refers to data that can be used within a specific local area. This \"local area\" usually refers to the administrative scope of a country, region, or city. Local carriers define the usage area of local data through the coverage of their base station networks, ensuring that the data is only valid within the set geographical range. Once you leave the covered area, the network signal will disappear. For example, local data purchased by Chinese users can generally only be used within mainland China. Once you leave this range, local data can no longer be consumed." msgstr "当地数据是指可以在特定本地区域内使用的数据。这个“本地区域”通常指的是一个国家、地区或城市的行政范围。当地运营商通过其基站网络的覆盖范围定义当地数据的使用区域，确保数据仅在设定的地理范围内有效。一旦离开覆盖区域，网络信号将消失。例如，中国用户购买的当地数据通常只能在中国大陆使用。一旦离开此范围，当地数据将无法再被使用。" ```

Global data breaks through the limitations of local networks. It can be used in multiple countries and regions, with a much wider coverage. Different global data plans cover varying numbers of countries and regions; some may include dozens of major countries, while others can cover hundreds of countries and regions. When global roaming service is activated, the device signal can automatically search for and connect to local partner carriers' networks. This means that no matter where you are in the world, as long as there is a network with a cooperation agreement with your mobile phone or the carrier of your IoT smart device, you can likely obtain communication services.

The cost of local data is relatively low. Since local carriers have invested heavily in local network construction, with mature coverage, their operating costs are relatively controllable. Therefore, they usually offer more affordable local data plans, and users can choose different capacity data packages according to their needs.

However, once global roaming data services are activated, the costs are significantly different. Global data traffic is generally charged by the amount of data used, and the unit price is relatively high. This is because providing global data involves cooperation with carriers from multiple countries and regions, requiring payment of cross-border network usage fees, settlement fees, etc., which significantly increases the cost.

Taking China as an example, many local data plans can provide dozens of gigabytes of data for just a few dozen yuan per month, with an average cost of only a few yuan per gigabyte. In contrast, global data is usually available in daily, weekly, or pay-as-you-go plans, with daily costs ranging from dozens to hundreds of yuan. Regardless of the type of data plan, it includes a certain amount of data, and additional fees will be incurred if the limit is exceeded.

When using local data within the coverage of its carrier's network, it can demonstrate excellent network speed and stability. In areas with good 5G network coverage, using local data allows you to enjoy high-speed data transmission, rarely experiencing lag or disconnection. Moreover, local carriers continuously optimize local networks, base stations, optical cables, and other infrastructure based on users' usage habits and needs to improve network performance, providing users with high-speed and stable network services.

网络数据的速度和稳定性受到多种因素的影响。由于各国和地区的网络基础设施建设水平不同，在使用全球数据时，在网络建设相对落后的国家和地区，您可能会遇到网络速度慢或不稳定的情况。相比之下，在一些网络建设成熟的发达国家，如美国，您可以享受高速数据服务。

If you live, work, or study in a certain area for a long time, or if your IoT smart devices are installed and fixed in a specific location, then local data is a suitable choice. Local data can meet daily internet needs, whether it is browsing web pages, using social software, online learning, remote work, or viewing security monitoring footage, providing economical and stable support.

Global data is mainly suitable for cross-border travel scenarios. For example, business people attending meetings or negotiating business abroad, or logistics transportation that needs long-term cross-regional monitoring, usually require uninterrupted data to handle work information. In such cases, global data can help users maintain network connectivity, avoiding inconvenience caused by lack of network.
