    I have sent the same SMS as START0 to 1909 but it is giving some error as service not available with master……… What is this error and why cant i activate DND??????

    Plz help!!!

    • Telecom Diary on 29th Feb' 12Reply

      Hello Sudhir,

      Normally to subscribe to NCPR for any mobile network, you have to send START 0 (with space between START & O) to 1909.
      Since, loop mobile has configured their server wrongly / not following TRAI guidelines or any reasons, START0 (without space between START & O) message to 1909 is working with Loop.
      As you failed sending message without space, try sending with space. Still failed, call 1909 from your mobile.

  21. Sudhir Nair on 27th Feb' 12Reply

    I am a new customer to loop mobile no – 9004095523. I have done an MNP from airtel to loop. Today for the first time i am trying to contact the customer care team and amazed to see that the team is disconnecting my calls again and again. At once i heard from the background saying that “Postpaid customers dont have any work and calling the customer care so dont answer”.

    This is really amazzing….. Need to work on it!!!!

    • Telecom Diary on 29th Feb' 12Reply

      Loop mobile must be hearing their Customers feedback.

  22. Suhas Gokhale on 17th Feb' 12Reply

    My prepaid loop mobile number is 9821133362. i am working as an Inspector in Mubai Police since last 26 years. I have tried to activate DND or NCPR on several occasions. I am getting a reply that currently the service is not available from masters. These so called masters are not higher than the Apex court of the country. I am continuously being disturbed by promotional messages. Should I sue Loop mobile for Mental harassment and contempt of court?

    • Telecom Diary on 17th Feb' 12Reply

      Hello Suhas Gokhale,

      As a consumer, you have every right to sue your service provider.
      Before that, try to send SMS START0 (no space between) to 1909 from your mobile number to subscribe to NCPR (old DND) or call 1909.
      If failed, as we said you can sue Loop in the consumer court.

  23. Hemant Sharma on 15th Feb' 12Reply
