So this merger will leave:
AT&T
Verizon
Sprint
MetroPCS ( actually bigger than U.S. Cellular)
U.S. Cellular
Do the subcontracting cellular companies count as competitors?
Like Boost and Clear, etc.?
Technically, it is "leasing" time and being a "Mobile Virtual Network Operator (MVNO)".
Boost and Virgin Mobile (USA) are already owned by Sprint. Cricket is independent but leverages Sprint; so there is no change there either.
U.S. Cellular leverages Verizon for national coverage. ( That would make much more sense to buy at some point than Sprint since already loosely integrated. )
Clear is also mostly owned by Sprint. Essentially, Sprint stuffed bandwidth into that separate entity. Again a move to get others to help build out the network (cable companies). Sprint's 4G leverages Clear's 4G.
Since all of these more narrow marketed services use Sprint, it would be tough for Verizon to get that deal past the US DOJ. They'd be way past the 50% mark in control (of direct and indirect subscribers). Sprint is big enough that they are really can't be bought easily by #1 and #2 ( doesn't matter which one is bigger at any one moment).
There are some TracPhone ( or something similar in pre-paid space) which may have been hooked to T-mobile but it is small.
Since I use Sprint, I would obviously prefer they buy T-Mobile.
That would be
horrible move by Sprint. They have already spent gobs of money trying to choke down Nextel's incompatible network. To go off and choke down T-Mobile's would be worse. What Sprint really wanted was for T-Mobile to help chip in and build out 4G (probably LTE) with them. I suppose they could have shared 4G roaming but didn't make sense to buy.
ATT probably just saved Sprint from themselves. The other upside for Sprint is that ATT won't have as much money and their own integration mess to sort out over next 3-4 years.
