Don't Connect between module SARA-R510M8S-61B with Soracom eSIM (SGEIL01)

Hi team,

I am testing the SARA-R510M8S module with a Soracom eSIM(SGEIL01). I scanned for available networks, but none were found, even though I have configured the APN and authentication as follows:
[08:22:07.844] AT+CGDCONT=1,“IP”,“soracom.io
[08:22:07.864] OK

[08:22:09.885] AT+UAUTHREQ=1,1,“sora”,“sora”
[08:22:09.905] OK

However, it is still not working.

I have connected the antenna correctly, and when I tested with a Vietnam carrier’s SIM card, it worked fine. I also removed the SIM card, soldered the eSIM onto the board, and was able to read the ICCID and IMSI, but I still couldn’t find any available networks.

I found a similar issue discussed in this forum thread: Unable to connect the SARA R510M8S module to the network with Hologram SIM, despite correct APN configuration in Vietnam. · Issue #52 · sparkfun/SparkFun_u-blox_SARA-R5_Arduino_Library · GitHub). However, the only suggestion I saw was to update the firmware. I couldn’t find any firmware updates for the SARA-R510M8S-61B-01, and I am currently using firmware version 03.25,A00.02.
Do I need any configuration?

Any help would be appreciated.

Thanks
Best regard,
Vu.
