How Does Cellular Data Work?
How does it work? Once a SIM card is in your mobile phone and powered on, it connects to a cell network through a wireless service tower nearby. This allows your phone to make calls, send and receive SMS, as well as connect to the Internet for Web browsing, email, social media, instant messaging, and other needs. Wireless towers come in all shapes and sizes these days, and some of them may not even appear to be towers, unless you take a closer look. But all cell phones communicate wireless through signals transmitted through these towers. All carriers have them.
Cellular data is available in various forms of advancement. Most cellular carriers here in the USA and Canada have shut down their legacy first generation networks and are in the process of shutting down 2G and 3G networks, too. But if we have to go back in time, cellular data includes CDMA 2000, GPRS, EDGE, UMTS, WCDMA, HSDPA, HSPA, 4G (LTE), and 5G. It is available wherever your wireless service provider has network coverage.
If your carrier has turned off their 2G and 3G networks, you will be able to use only 4G and 5G for data on their service. Almost all US carriers have total 4G coverage now, and 5G coverage is increasing at a fast pace, so this is not a problem. Just be sure to buy a cell phone that is 4G or 5G enabled. If interested in 5G, here is an article detailing where 5G is available in the USA.
Should Cellular Data Be On Or Off?
If you have a SIM card in your phone, have a data plan subscription, cellular data will be on by default. Thankfully, here in the US, unlimited data plans are available for a small monthly fee from many carriers. If you choose not to use cellular data (perhaps you have WiFi access at home and at work, you can simply turn the feature off on your smartphone and not bother with a subscription from your carrier. Many cell phone users in the United States do this; you will not be alone.
You can conserve cellular data by turning it off. Leaving it on can also be a massive drain on your phone’s battery, especially in areas with poor cellular signal or coverage.
