As I write, the Internet is atwitter with merger talks between T-Mobile and Sprint.
In the last couple years, T-Mobile has grown rapidly and competed well by marketing itself as a consumer-friendly, scrappy underdog. It's worked well.
In the same time frame, Sprint was acquired by SoftBank, one of Japan's largest and most successful companies. It's also one of Japan's three mobile carriers (unlike the US's four) and led by Masayoshi Son, an outspoken CEO. Son now acts as the face of Sprint.
SoftBank is in both wired and wireless in Japan, so I thought I'd share some distinctions between those two, and with T-Mobile.
Wired Broadband
Mobile
iPhone 5 on SoftBank, Japan
iPhone 5 on T-Mobile US
Device: $549 or more up front (example here is a current iPhone 5c, 16GB. I paid $649 when moving last year)
BYOD
Lowest usable monthly bill baseline: $30 (prepaid with automatic credit card billing)
What's included: 5GB LTE data and 100 minutes talk time
Talk minutes: 10 cents per minute
Total outlay in two years, if you almost never make calls: $1,269 (1/3rd cheaper)
No contract, no ETF.
The moral of the story
When Son-san talks to American audiences about wired broadband speeds, he may have a leg to stand on, but it's irrelevant to the transaction that's really at hand. SoftBank the mobile carrier implies Japanese precedents for slower speeds, higher prices, purposely incomprehensible plan structures, rigid contracts, and unhappy customers.
That makes SoftBank a profitable and successful company in Japan. It doesn't get much better on other carriers because there are only two more and neither of them is interested in price competition.
Personally, I would expect the profitable and successful SoftBank, not the happy-sunshine-unicorns SoftBank, to take control of one of potentially 3 American mobile carriers.
