  1. Hi,

    I am new in this forum.I want to establish a ppp connection with atdt dialup.But it hangs on atdt*99# command and while using atdt commands with all parameters(APN,LInkProtocol and CID value) it shows “No Carrier”.Any Solutions?Thank You.

      1. Thank you for the response.

        As per the question,

        The modem ‘hangs’ means it does not communicate further until it is rebooted.It does not reply anything nor takes any command till then.
