The Giant DoCoMo is in War with some unscrupulous clients. 1Seg the mobile Digital TV, is available in Japan since March, and DoCoMo is facing a horrible problem. A huge number of its 1Seg clients, purchase a 1Seg phone and cancel their subscription 1 or 2 days after their purchase in order to use this phone as a mobile Digital TV only and not as a phone. Unlike its competitors, DoCoMo didn’t lock the 1Seg function. Operators like Vodafone or KDDI, has a system which allow them to shutdown the 1Seg function the same very moment you cancel your subscription. Each time that a client decide to cancel its subscription DoCoMo is roughly loosing 250 EUR per phone, and they sold over 120 000 units so far. Now DoCoMo will soon release a new 1Seg terminal which will block the 1Seg features if you are willing to cancel your subscription.
