EM7565 modem unable to read sim profiles


#1

I’m having a little bit of trouble with my EM7565 modem paired with a verizon sim or an ATT sim.

When I hook up a verizon sim for example I only see the following profile when I run AT+CGDCONT?
+CGDCONT: 1,“IPV4V6”,"",“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0

Same with ATT. I’m able to get the rest of the information from the sim no problem such as the IMSI, ICCID, etc. Is the modem just having trouble reading the profiles on the verizon/ATT sim?

I have the modem hooked up to my linux machine using libqmi to access it and AT commands of course.

Thanks for any help!

Can you provide responses to following AT commands from your module:
ATI
AT!IMPREF?
AT!PRIID?

Since you are on Generic configuration, the firmware is not setup for any specific carrier i.e. AT&T or VZW. Ideally, you need to use the carrier specific FW from our site: https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime-em_mc75xx-approved-fw-packages/
We do not yet have approved FW for these carriers yet.

Meanwhile, you may try configuring the APN specifically for AT&T via the AT+CGDCONT command on the generic FW you have, this will allow you to setup for basic data connectivity.
