How Does Cellular Data Work?

What is Cellular Data?

Cellular data is a service provided by mobile providers to allow people to connect to the internet without Wi-Fi.

How Does It Work?

Wi-Fi uses radio waves to transmit information from devices to a Wi-Fi router. The waves can be either 2.4 or 5 GHz (GHz, or giga-hertz, are a way of measuring the frequency of waves). Mobile carriers offer another way to access Wi-Fi. Cellular data uses the network provided by carriers, which is also the same network used to make phone calls. While Wi-Fi has a limited range, cellular data works wherever the carrier provides coverage.

How Can You Save Mobile Data?

Since cellular data plans cost money, there are many ways to save on data. First, identify the sources that take up the most data on your phone.

  • Social Media and Video-Playing Apps

Social media apps quietly use your data to update and refresh, eating up a lot of data. Since these apps need the data to stream their information, turning data off for them when not using them or turning data off completely is very helpful. Apps that play videos also significantly contribute to data usage, especially high-quality videos that need more resources. Turning off auto-play for specific apps or watching videos with Wi-Fi instead of data can help.

  • Web Browsers

Since web browsers are a gateway to the internet, it is natural that they use up a lot of data and resources to show results for searches and other things. Using web browsers less on data or using browsers like Brave, which block unnecessary cookies and trackers and therefore use less data, can help.


Cellular data is a handy feature to have when there is no available Wi-Fi and is very useful in situations where access to the internet is necessary. Saving data is equally important, as saving data on your cellular plan can save money.
