We all know that Tata Docomo mobile operators it is a main network in Japan there called as only docomo they tie-up with Tata in India and released as Tata Docomo but one of the best mobile operator I think so because I using this Sim from past 4years this network changed the total mobile rates in India by this network total call rates are decreased. Mean while sms packs, Internet packs also very low rates.
Thank you for Tata Docomo for such a great services.
