Cm radio apn <apn> == invalid command for radio service

I’m getting a “invalid command for radio service” when I try to issue the “cm radio apn m2m.com.attz” command.

My device details are as follows:

Device: WP8548
IMEI:
FSN:
Firmware: SWI9X15Y_07.12.09.00 r34123 CARMD-EV-FRMWR1 2017/04/26 23:34:19
Bootloader: SWI9X15Y_07.12.09.00 r34123 CARMD-EV-FRMWR1 2017/04/26 23:34:19
priIdPn: 9906351
priIdRev: 01.01
skuId: 1103113

Legato: 16.10.3_4886ffbf7109055d3448bdff81805ff7_modified

This was not a problem until I updated the firmware on the device. I did select the Carrier: ATT version from inside Development Studio.

Any help would be greatly appreciated.

it should be
cm data apn

Thanks! Definitely got the radio and data commands mixed up in this case.
