My device was working perfectly yesterday and today I am getting error code 6. I found where the error codes are explained but the description of error does not provide any information on what I should try.

Here is what sending an SMS with the web client looks like:

Send MT-SMS accepted. Operation in progress
Send MT-SMS failed. Cause: AerFrame ErrorCode 6

Here is what I get back using the API:

Here is a description of what error code 6 means:

6 - channel unacceptable - This cause indicates the channel most recently identified is not acceptable to the sending entity for use in this call.

Any idea what I should try to fix it?
