Em7565 no 3xCA on band 41

I’m using the em7565 with sprint in a 3xCA area confirmed with a note 8 phone. I am only getting 2xCA. I should be getting 3xCA with band 41. (41+41+41)

Are you using a Note 8 with a Snapdragon SoC? Only the Snapdragon version shares the same modem. You should ensure the Snapdragon X16 (Modem) supports this band combination.

My sprint note 8 uses the Snapdragon 835 ( which holds the X16 modem) and it does support 41+41+41

I locked band 41 and now it works.

I am also from Ausrtria with B1+B3+B7
Modulation not always work only for 1 Band.
In the evening Primary serving cell jump to other in my case B3 and it work

How we can select Primary serving cell by own or lock to it .Is this possible ?
I set Modulation Report to 1 at+MR=1 but nothing happen I can see no status. It is in +GCAP not integrate .

I see in Reference book something about RRC (Radio Resource Control)but I can not found it in Modem
!CUSTOM commands

“LTEREJDELAY”—Set delay before LTE attach requests are sent after TAU or
service request rejection.
:
• 0–255 = Delay in 10 msec units. (e.g. 10=100 msec)
• Actual range is 0–2.55 sec
• Delay is cancelled if RRC connection is released early.
• Suggested value (if delay is being enabled) is 50 (500 msec). Adjust the
value as necessary based on testing.
