These still exist, except it’s not a number you call, it’s a shortwave station that you tune into.
Check out http://websdr.org/ if you don’t have your own. From there you can play with various shortwave radios from around the world. The first one on my list is my favorite cause it picks up a lot of stuff.
Not to mention the hilariously tiny storage space. My TV came out in 2022, and has 8 freaking gigabytes of storage space. That’s right, eight. Before I removed all the pre-installed bloat with ADB, it barely had enough space left to install one app fresh out of the box. It’s like these smart TV manufacturers expect people to only use the built-in apps and nothing else ever.
