I can not get work at china mobile N41 5G network . modem only registeredat China mobile lte network.I can confirm sim card work at 5G with quectel RM500Q and Simcom8200 at china mobile SA network at same time and sameplace.
I can work at 5G NSA at china telecom N78 with EM9190. I want to force EM9190 to NSA for china mobile ,is it possible?

Hi,

May I know how many antennas you used for this test?
At least you need to have main and aux antennas used for n41.

Hi,

If you want to test n41 SA, please try below.

  1. ensure 4 antennas are used and it can support n41
  2. issue AT command at!selrat=05 and then at!reset
  3. show me the result of AT!band=?

before I change at!selrat=05 ,I at!gstatus?
