Uh
MVNOs use big carriers..they are just resellers
Uh, like, your response post, Juan, is the definition of an MVNO.
We all learned so much from it! Thank you for stating the obvious and redundant. Putting your humor aside, the point is Dish, with its ownership of Boost Mobile, is currently operating as an MVNO and will eventually operate as part MVNO and part 4th carrier network. Further, while the big carriers also own and operate their own "MVNO's" so to speak (and I presume you knew that?), they, too, have find gold in them there hills.
The fact of true MVNO's piggy backing on the big carriers network is irrelevant to the point that these MVNO companies have and continue to steal large numbers of customers away from the big 3 and on to their much less expensive services. The numerous TV commercials for each of them, including the Ryan Reynolds pitch for Mint Mobile is evidence of the all the MVNO"s momentum and why Verizon is picking up the grand-daddy of all MVNO's: TracFine inc, with its numerous brands for various segments of the market. Even the "MVNO's" owned by the big 2 (Verizon's was a diaster, and that is why they have bought TracFone, inc.) have impressive number of customers and are making money working both sides of the street. Expect MVNO businesses to continue impressive growth, and the fact that MVNO's piggyback on the big carriers is a fact that the vast majority of MVNO customers don't know, and--unless they are savvy and want to use, say, Verizon's network--don't care.
