The bread and butter of mobile operators is infrastructure and spectrum licensing. FWIW I think there's a fair amount of competition, at least more than you see in the ISP space. Building towers is usually much more straightforward than trenching fiber/cable.
Mobile companies in general don't compete with each other at all and just continuously raise prices until too many customers starts leaving or regulators and politicians start to notice.
My local WISP uses AirFiber[1] for all their backhauls, mobile can be different but nothing is an absolute.
There are remote towers that actually have satellite backhaul. You can tell when you're on UMTS/HSPA or LTE and the latency is like 700ms. The companies are trying to eliminate them as they are costly to operate.
There was a bit of a scandal back then because of the way the Dutch government handled that auction and tried to squeeze as much money as possible out of the various bidding companies.
But the only other solution I can see is to have the government just pick a company and hand them the license, and that's effectively guaranteed to be breathtakingly corrupt since the incentives to cheat are overwhelming. At least with the market solution the money goes into the government's general fund instead of into the pockets of the party official in charge of making the decision.
Isn't it exactly the other way around? They bid high because they estimate that they will be able to make back the investment. The sole reason for making that investment is to sell it on to customers.
It’s a but like broadband and electricity deregulation in UK or NZ.
The majority of cost aren't spectrum, ( as a few comment below suggested ) or Infrastructure, ( Payment made to Nokia, Ericsson, Huawei, or ZTE ), but rental agreement for all those Base station.
It is not exactly license to print money like Casino, Oil industry. The telecom industry margin are generally quite thin.
The customers don't literally participate in the auction, obviously, but the operators bid based on what they think customers will pay. It's like the representative democracy version of an auction.
Prices could be mitigated by competition but usualy we have oligopoly, by regulators (EU and roaming charges) or by taxation (licences to operate).
I always laugh when similar company with similar shareholders charge 15 times more in one country then in another.
