ESM Reject Code 38

Hi,

My Thingy91 has suddenly stopped connecting to the mobile network. It came with an ibasis SIM which has data, but since this morning I am getting an ESM 38 + EMM 19 error. I thought it might have to do with my own code, and flashed the latest modem firmware plug GNSS sample but the problem persists. Below is an extract from LTE Link Monitor:

As you can see, there is an ESM code 38 followed by an EMM code 19. Apparently ESM 38 means "the requested service was rejected due to an error situation in the network" and EMM 19 means something was wrong with EMS (there is a failure in the ESM message contained in the EMM message).

Does this mean there is a problem with ibasis (or whoever ibasis has a roaming agreement with here in Australia) network?

  • Hi,

     

    Cause code 19 and 38 indicates that you're not allowed to roam to the network you're connecting to.

    I would recommend that you contact iBasis and ask about this, or contact your local network provider and ask if they have any iot subscriptions (to get a home registered SIM)

     

    Kind regards,

    Håkon

  • Hi Håkon,

    Thanks for your quick reply. Two follow-up questions, if you don't mind:

    1. Does iBasis even have an end-user facing dashboard / support mechanism? I used to charge the sim card through nrfcloud.com, and looking at iBasis website it seems like their target audience is not developers / end-users.
    2. Is the reason for my normal sim card not working the fact that my network supports FD-LTE, TD-LTE and LTE-A, while Thingy 91 connects to LTE-M?

    Kind Regards,
    Iman

  • Hi again,

    Just another update, looks like there was a network wide issue with Telstra for LTE-M here down under. Everything has started working again. Thanks for your help, and at least I learned something new.

    Kind Regards,
    Iman
