Depending on the country where you live, this was one of the few ways to access the internet decades ago. It still exists today—though it’s now 4G and works much better—but it’s generally used by people who need internet access while away from home, such as streamers who film "IRL" (in real life) content. So, while it’s still in use, it serves a very specific purpose—unlike in the past, when it was used as a primary home internet solution in remote areas where no other connectivity was available. Do you remember this? Did you ever use it, or do you still use it today? For instance, it’s quite useful when you’re away from home—at an internet café, a restaurant, or an airport—and want to avoid the security risks of connecting to public Wi-Fi; you simply connect via a 4G modem, and you’re all set. Why use a dedicated modem instead of your phone? The signal is much more stable, it doesn’t rely on a battery (you just plug it in and go), you can use it for as long as you like, and the upload and download speeds are generally faster than what you’d get by using your phone as a hotspot for your laptop.
