Hello,
I am using module MC7710 in our device for connection to LTE. When I use !SELRAT=0(automatic selection) LTE connection works well. But when I use !SELRAT=6 (LTE only) module cannot attach to network. EMM state is still “Deregistered” and “Attach needed”
!GSTATUS:

Bootup Time: 1 Mode: ONLINE
System mode: LTE PS state: Not attached
LTE band: B20 LTE bw: 10 MHz
LTE Rx chan: 6400 LTE Tx chan: 24400
EMM state: Deregistered Attach Needed
EMM connection:RRC Idle

Have you ever seen this problem?
