the main problem is that the apple phones have bigger subsidies because apple can command whatever they want because people will leave your carrier and the carrier will have less "prestige" if the iphone is not on there.
verizon / att / sprint obviously make less per apple customer than per android customer.
sprint doesnt EVER make money so they just lose MORE per customer.
i mean assuming every iphone and android customer all use generally the same data / text / minutes plan on average. then the monthly is the same but apple gets larger subsidies.
so yes, apple either makes them less, or in sprints case loses them more net at the end of the day.
now the main reason for it being particularly bad in q4 is that iphone releases the iphone in q4 so that is when all the subsidy costs are booked. if you smooth the subsidy out over 4 quarters (given they release one iphone per year, and presumeably this large capital expense would only happen once) then its more indicative of how to compare it against say android users.
i mean the phone subsidy has to be made back over 20 months or whenever the next subsidy has to be paid to keep said user. just apple releasing their main phone all in one quarter (unlike android releases which tend to be spread out all year) makes a huge surge in subsidy costs all during 1 quarter as well.
its the opposite of the whole apple sales argument. the quarter the telcos all have to book the subsidy expense is always the quarter that apple has the largest profits. of course apple sales will be much less in the other 3 quarters, and subsidy expenses will be less in the other 3 as well (they will still sell phones in other quarters, but just not the typical apple release surge in the quarter of release).
that said, apple still commands a high subsidy. and since all users pay the same for monthly service, the apple users are getting a good deal relative to android users. so they raise prices on EVERYONES phone plans / upgrade plans.
in reality they should just charge apple users more for the same plan, or subsidize their phones less. the phone companies havent been able to do this as of yet, because before they were competing just to be able to offer the phone. now that all 3 of them have the iphone i bet you'll see them raise prices on iphone upfront or whatever depending on how much they care to actually keep the apple less profitable apple users.
i mean in the end, the only company not subsidizing apple users is t-mobile. if t-mobile had an equivalent network, in theory t-mobile given they have only the more profitable android users could offer phones for less, or cheaper service. AND THEY DO.
sprint i am not even sure has an actual business plan. paying 20 billion to get a bunch of relatively unprofitable users given their slim margins doesnt seem to do very much for them, unless they eventaully convince those users to stay WHILE increasing prices. who knows how sticky users are, or if they are willing to just hop providers . sprint's network sucks so i suppose the only way they will keep them is if they improve their network, and then maybe they can justify a price increase to the equivalent of verizon/att . i mean if you only wanted an iphone , were already on sprint and sprint's network was hypothetically as good as verizons in every single way, then in theory sprint could charge just as much as verizon right? i would assume long term that is their plan, because it would be pointless to sign on the iphone and just lose money on it ...
