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?

```auto
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:

```auto
cm data apn NXTGENPHONE
```

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

Hope it helps.  
Rgs,
