Cm radio error!

I am trying to connect to the network using my FX30. I have installed an At&T SIM card on it and when I try the cm radio command, the following output is seen.

Status: Registration was denied, usually because of invalid access credentials (LE_MRC_REG_DENIED)

Can someone help me with this?

Hi virajrp,
Can you share response for below?

cm radio
cm data

Is it on LTE mode? Have you configure the APN name for the subscription?
Please try configure the APN name using below commands:

cm data apn NXTGENPHONE

(If your SIM’s APN is not “NXTGENPHONE”, please modify accordingly)

Hope it helps.
