    We have a SIM card that was activated and is working fine on a MTSMC-H5.
    We tried using the same SIM card on a brand new MTSMC-H5-IP and we are not able to connect to the network. We use linux ppp script to connect our device to the internet. The error happens when the “ATD*9***1#” command is executed.
    The same SIM works fine with a old MTSMC-H5 module.

    Questions
    1. Does the new MTSMC-H5-IP module need to be activated or provisioned for the AT&T network?
    2. Is there is any configuration that needs to be set on the modem to use a particular network?

    Thanks,
    Siva

    Hi Siva,
    The MTSMC-H5-IP is intended to be used as a simple device server using an internal ppp implementation and IP stack. By default the device server application will respond with ERROR to the ATD command. There is a pass-through option (AT+WOPEN=5) that may allow you to bring up a network link using pppd, however we don’t recommend using the MTSMC-H5-IP in a Linux environment (the MTSMC-H5 is the correct choice).

    I got the same problem on model MTSMC-H4-IP but AT+WOPEN=5 is not working.
    Is there other solution for MTSMC-H4-IP to use pppd on Linux ????
