Just received this and it doesn't connect. I contacted Truphone and they were not much help. They did mention to make sure the apn is iot.truphone.com.
I know almost nothing about this device and the instructions are sparse but I did find a menu item for Cellular Service. It did not have anything in the apn field. I set the menu as follows:
Sim Slot 0: 1 (MODEM EMBEDDED SIM)
APN: iot.truphone.com
CID: 1
username:
password:
modem target_state: 2
attachment timeout: 180000 ms
Network register mode: 0 = Auto
Operator name format: 9 = Not present
Operator name: 00101
Access techno present: Not present
Network register mode: 7 = CatM1
Low power inactivity timeout: 1000 ms
NFMC activation : 0
It still does not connect. Are these values ok?
Also it seems the my.murata.com website is not accepting new logins. So how can I get further information about this board?

Yes, I am aware of that webinar. I registered for it a couple of days ago but got no login details.
I will watch it live when it comes out on demand.
Thanks for participating in it!

Hi,
I am having the same issue in Australia.
+CEREG: 2,3<CR><LF>
ATCModem:NetworkState (EPS) = REGISTRATION_DENIED
The Truphone SIM is activated.
Australia is covered according to https://www.truphone.com/things/plans/coverage/?feature=LTE-M
I have tried the unit with the embedded sim and two local sims. I have tried all combinations of tech.
None of the SIMs have registered any network traffic at all.
I have run it >10 times and have let it run for long periods.
I have also tried only the embedded SIM and only the SIM socket at other times.
I have tried in two locations, both with good reception.
Here are my current settings:
Sim Slot 0: 0 (MODEM SOCKET)
APN: iot.truphone.com
CID: 1
username:
password:
Sim Slot 1: 1 (MODEM EMBEDDED SIM)
APN: iot.truphone.com
CID: 2
username:
password:
modem target_state: 2
attachment timeout: 180000 ms
Network register mode: 0 = Auto
Operator name format: 9 = Not present
Operator name: 00101
Access techno present: Not present
Network register mode: 7 = CatM1
Low power inactivity timeout: 1000 ms
NFMC activation : 0
I have also set NWOPER=TRUPHONE
$>at at%nwoper?
ATParser:*** SEND (size=11) ***
at%nwoper?<CR>
<CR><LF>
%NWOPER: "TRUPHONE"<CR><LF>

When I try the at%ceer? command I appear to get a truncated output, see below
$>at at%ceer?
ATParser:*** SEND (size=9) ***

<CR><LF>
ATParser: Big frame (display deactivated)
<CR><LF>

Firstly, how can I enable the "Big frame" display?
Secondly, any update on the best process to address this issue?
Thanks in advance,

Hi, I', In Thailand and also in Truphone list
I also got
ATCModem:NetworkState (EPS) = REGISTRATION_DENIED<LF><CR>
Firmware out of the box haven't been updated yet.
Anyone can tell me how to set APN for 2 sim (eSim and external plastic sim)?
If I cannot make Truphone work, I will try external sim card, I have TRUE(Operator in Thailand) NB-IoT and LTE-M1 sim card.
How to get below information? I used Keil not STM32IDE
Sim Slot 0: 0 (MODEM SOCKET)

Please help? I guest many people face this problem as well.
Anyone has AT command to share? Or any guide line document for setting APN?

So is it work in Thailand?
I need to test with external plastic sim from Thai operator, do you have step by step setting guide?
It's not ok for this difficulty and unclear documents.
I almost give up and change solution to MCU + Simcom or Quectel modems that I can control every step.
Best Regards,
Please help.
I will use your module in electronic water meter in Thailand and Vietnam markets.

I manage to use TRUE( Local ISP operator in Thailand) NB-IOT sim card successfully but only for NB-IOT not LTE-M1
By setting
at at%nwoper="DEFAULT"
at at%setacfg=radiom.config.preferred_rat_list,"NBIOT"
Default firmware "none" and "CatM" don't work. (REGISTRATION_DENIED)
Is it should be "CATM" or "CatM"?, very frustrate without AT command document
However, no luck on Truphone both CatM and NBIOT
After long waiting period always return
AT%CEER?<CR><LF><CR>
<CR><LF><LF><CR>
%CEER: 1,"NAS-EMM","ATTACH","REJECT",#15,NO_SUITABLE_CELLS_IN_TRACKING_AREA<CR><LF><LF><CR>

I guess my location not coverage by Truphone, even Thailand is in their Country list.
FYI

About a few weeks ago, I managed to make my board to use eSIM by truphone to connect to Internet.
Today suddenly it stopped working after I flashed the original binary code (l462_t1se_socket_v520.bin in STM32CubeExpansion_CELLULAR_V5.2.0\Projects\B_L462E\Demonstrations\Cellular\Binaries) into it.
It always says "SIM not inserted", even I select slot 0. I tried slot 1 as well, same result.
It's really strange and annoying. I attached the print-2-screen log for your info.
Can anyone give some comments?
2022-06-03 06:15 AM
Dear HDaji.1
It is indeed strange since the eSIM is always present. The X-CUBE-CELLULAR firmware does not change perfom any control to the eSIM. Please, can you try to use the X-CUBE-CELLULAR 700 to get more information about the SIM selection configuration.

Hi Solofo,
Can you be more specific on what I need to do?
There are many pieces of info sheets and how-to documents about this board, um2567, 2426, 2743, etc. I just cannot find anything related to trouble-shooting eSIM.
If SIM card is not found, it's not helpful to use AT command to retrieve SIM info, is it?
BTW, I think I have changed (messed up) content of EEPROM. Is it the cause? I guess not.

I am in the USA in the state of Wisconsin experiencing the same issues. I just purchased the B-L462E-CELL1 board two weeks ago and TRUPHONE has been very little help. I get an average of a new question from them every 2-3 days. Has anyone compiled a list of the steps to solve the REGISTRATION DENIED problem?
