Could you provide the output of AT+CPMS=? so that we know why the modem
didn't like the CPMS configuration?

Also the model string as reported by the modem in AT+CGMM or AT+GMM
could help to try to look for the appropriate AT command reference.

AFAIK the rate is really several seconds between queries, so I'm not
