mr1100 cannot obtain ip address

I have an unlocked ATT Nighthawk MR100 router.  Originaly I could connect with it through a browser on either my laptop or phone and entered the unlock code.  Then was able to change the APN to the correct one.

 

But when I put in a SIM for my cell company I then get the error message Device locked visit http://attwifimanager

 

Both my phone and laptop can see the wifi connection to the ATT-WIFI-bYN3.  But fail on connection due to not getting an IP address.  Even if I tqke the SIM back out it cannot connect due to IP issues.

 

The Netgear app from this site aslo says the ATT-WIFI-bYN3 is not supported by the app.  version 7.14.1909.192

 

Would doing a factory reset lock it back to ATT?

 

Using Win 10 and a MOTO G7 phone.

    I had to do a factory reset and then enter the unlock code again.  It all worked then when I put the new SIM in.  It is a TMobile SIM.

    What SIM card you used here? The above info shows that your device is not unlocked from AT&T.

     

    Thanks
