What's the Difference Between Local Data and Global Roaming?

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.

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.

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.

The network speed and stability of global data are affected by various factors. Since the level of network infrastructure construction varies across countries and regions, when using global data, in countries and regions with relatively backward network construction, you may encounter slow or unstable network speeds. In contrast, in some developed countries with mature network construction, such as the United States, you can enjoy high-speed data services.

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.
