Product Discussion Pepwave MAX

Hello

I’m trying to send an SMS from my MAX Transit Duo. It responds with “fail” status and “Unsupported request” message.

It worked before and now I receiving this response on a several routers.

Other requests such as getting access token and WAN connection status is ok.
I’m tried to put SIM into my phone and to send an SMS and it worked.

The documentation for this router does not contain information about this type of response, as well as possible causes and solutions.

Thank you!

I had a similar problem when trying to SMS from my modem to activate a T-Mobile account online access. I found a topic that discussed upgrading the cellular modem firmware. This is not the same as the device firmware. I upgraded it, and now the SMS works. You have to refresh the page, however, to receive the SMS texts.

Discussion/process on upgrading the cellular modem firmware can be found here:
