It's not artificial if the network is overloaded by users. It's not like fiber where an optical running from user end point to the ISP can be fully saturated all the time without affecting other users.
Yes, but that's an entirely different problem. It's not like imposing fees after a certain point of use will help that problem at all, it would make more sense to a) absorb it and raise the monthly subscription when necessary, b) charge per byte, c) charge based on your % of network, or charge maintenance or service fees and don't charge for bandwidth at all. The current, tiered model only makes sense to use "overloading the network" as an excuse to abuse monopolies and overcharge customers.
The US mobile network system has plenty of competition presently. In fact, it's competitive enough that it has evolved faster faster and better than most European mobile networks. It took nearly all of Europe a very long time to get 4G adoption above even 50% of the population.
Maybe in some places, but the competition in the US is a joke. You either go with a decent plan but terrible service (Sprint), or you go with good service with virtually no control over your use (Verizon/AT&T).
Are you for real? It's easy. Look at prices and services from all major carriers in the US over the past 5 years. the prices are going down and you're getting more for less. It's a tough back and forth and every month or two they try to one up each other. So that's how prices are going down.
What you got in a different market doesn't matter. It's inarguable that prices are going down and it's inarguable that there is no monopoly. There isn't even a duopoly. What is arguable is that you should perhaps get more for what you pay. But the velocity is still down, even if it's not yet as low as it should be.
Original plans were unlimited 3g data. All t-mobile high speed data plans automatically included unlimited low speed data if you go over. They also have an unlimited 4g lte plan that's only $30 more than the basic 1gb plan. And they currently have a special offers to for 2 lines w/ unlimited data.
I had the original unlimited 3g data plan with AT&T. That also required paying $20 a month to get unlimited texts. I think I paid $10 a month for 250 monthly texts because that's all I needed. That was the height of mobile pricing bullshit in my eyes.
In South-East Asia, you often get a prepaid contract including 5 GB for between $5 and $20. This is 10x cheaper. Sure, salaries are lower, but the equipment is the same.
