EM9191 Not Trying to Connect to Verizon 5G

IoT Modules
1

Hi, I am having an issue getting my EM9191 module to connect to the Verizon 5G network. It is connected over LTE, but for some reason it won’t connect to 5G. I’ve updated the firmware to “03.10.11.00” and the current config is “VERIZON_030.067_000”. I’m set up in an upstairs bedroom where other devices are able to connect to Verizon 5G, so I don’t think physical area is a factor. I’ve attached some screenshots that will hopefully be helpful. I am stumped on what to do at this point and would appreciate some help.

have you checked “AT!SELRAT?” and “AT!BAND?” to see if there is abnormal setting?
BTW, you need to keep generating some data traffic, otherwise it would stay in LTE mode.

I appreciate the quick reply. I’ve attached a screenshot of the output of AT!SELRAT? and AT!BAND?, but it looks okay to me. Also, keeping constant data is a good to know. However, I’ve started doing that and am still seeing the same thing.

how about checking AT!RATCA? and AT!SDPREF?

BTW, seems you did not connect MIMO1 and MIMO2 antennas.
you can see if there is any improvement for connecting 4 antennas

Here is the output of those commands. I have all 4 antennas plugged in already. How are you able to tell I only have 2?

I re-connected all 4 of the antennas and this is the updated !GSTATUS? command.

according to PTS:

B66 should be also using MIMO1 and MIMO2, but from your original AT!GSTATUS, there is no MIMO RSRP.

is it because the signal strength is not good to have 5G?

I switched from a Verizon sim card to the T-Mobile one in my phone and was immediately able to connect to the 5G network. Same physical location. Here is the result of the !GSTATUS command. Could a lack of signal be the reason why it’s preferring 4G over 5G in the case of Verizon?

not sure, but the RSRP of TMO case is better

I have the same issue to connect this to the Telstra Network.

have you checked “AT!SELRAT?” and “AT!BAND?” to see if there is abnormal setting?

What is the return of “AT!GSTATUS?” now?
