It is not only the largest mobile operator in Japan by subscribers with a 45% market share. NTT DoCoMo also carries nearly all the mobile traffic of the crooks and criminals, said the country’s National Police Agency.
NTT DoCoMo’s two rivals, KDDI and Softbank, sell number of corporate connections according to the headcounts of a business entity. Softbank Mobile checks the purpose of subscription before closing deals with corporate clients. Its dealers are also obligated to verify the customer’s identity.
NTT DoCoMo, however, doesn’t waste any time for such “stupid things” before closing corporate deals. As a result, Japan’s National Police Agency found that 98% of the phones being used by the criminals are connected to the DoCoMo network.
