outgoing – incomming call NO CARRIER

3 thoughts on “outgoing – incomming call NO CARRIER

  1. hello,

    i’m using evaluating a UL865 and a GL865V3.

    my data socket tcp connection work.

    i could send and ecv sms.

    but i’m not able to make or recv a call.

    outgoing call, after ATD cmd i recv "NO CARRIER"

    incoming call, i sax the ring, after ATA "NO CARRIER"

    You can look my log file.

    Do i miss a particular init command process?

    1. 1. dial ATD<number>; (ie. terminated with 😉 for voice calls, make sure the number is valid.


      2. send ATA immediately after RING, not after ATH which terminates the call.
