Where does it come from(the bandwidth GB etc) and why do companies pay telecom department for the data they give to customers?
Why is that if I didn’t renew my connection, internet is being cutoff from my end eventhough my phone is wireless and it can connect to satellite?

“The internet” is a big network of connected computers (a network of networks). Absolutely nothing stops you from making a network within your own home, lots of people do that. But if you want to connect to another computer far away, e.g. the Reddit servers, you need some way to talk to those computers. You don’t have a wire from your home network to Reddit’s server.
It’s entirely possible to run your own network cable (or, equivalently, a dedicated microwave or satellite link) between your house and Reddit, assuming you could get Reddit to agree to connect it on their end. That would let you bypass the internet entirely. It would also be ludicrously expensive.
The easiest way to connect to other computers is to pay somebody who already has connections to all the networks to piggyback on their network…and that’s what a telecom company does. They have wires/microwave links/fibers between most networks within their coverage area, and agreements & connections to other telecoms for other areas. Between them, they can connect any two networks on earth. So, rather than build your own telecom network from scratch (which you can totally do) and negotiate with every network you might want to connect to (which you can totally do), you just pay a small amount each month to access the network of somebody who already did all that work. This is *far* cheaper and more efficient.
Your phone is wireless. It’s probably not connecting to a satellite unless it’s a sat phone, virtually all consumer phones connect to terrestrial cell towers (big sticks with antennas at the top). But that just covers the wireless portion of the journey…in order to connect to anything interesting, the cell tower needs a connection to the internet, which is against down to wires/fibers/microwave/satellite links. And so you have to pay to get access to the telecom’s cellular network, which is in turn connected to their hardwire network that lets you connect to other computers, which is what you wanted in the first place.
It’s like saying “What’s to stop me from creating my own highway system?” You totally can. You’re allowed to build whatever roads you want on your own property (not counting building codes and such). But if you want to actually drive anywhere fun, you need roads between you and your destination. Rather than build all your own roads, which is at least theoretically possible, it’s a heck of a lot easier to share a road network that somebody else already built.
