DoCoMo Subscribers Drop
DoCoMo reported a couple of days ago its first-ever drop in subscribers to its mobile phone service. In the month of November,17,500 more people canceled their service than signed up for it. KDDI and Softbank both had increases, of 324,900 and 68,700, respectively.
This is probably due to the start of number portability. It's now possible to change providers and keep your phone number, though of course not your keitai's email address.
