Data connect using external usim

I said I use EXTERNAL SLOT using AT COMMAND.

But when I try to connect the data, the APN changes like this.

root@swi-m9x28-wp:~# cm data
Index: 1
APN: iot.swir
PDP Type: IPV4
Connected: no

The first time you enter cm radio,

root@swi-m9x28-wp:~# cm radio
Power: ON
Current Network Operator: KOR LG Uplus
Current RAT: Module not registered on network, RAT not available
Status: Not registered but curiously searching for a new operator (LE_MRC_REG_SEARCHING)
Signal: Strong signal strength (4)
PS: Packet switched not registered (LE_MRC_REG_NONE)

It’s connected well to the LG Uplus I’m going to use, but over time,

root@swi-m9x28-wp:~# cm radio
Power: ON
Current Network Operator: KOR SK Telecom
Current RAT: Module not registered on network, RAT not available
Status: Registration was denied, userfully because of invalid access credit (LE_MRC_REG_DENIED)
Signal: Very strong signal strength (5)
PS: Packet switched not registered (LE_MRC_REG_NONE)

It is connected to the iot inner usim.

Below is the current usim status.

root@swi-m9x28-wp:~# cm sim info
Type: EXTERNAL_SLOT_1
ICCID: 8982067592002044433.
Home Network Operator: KOR LG Uplus
EID:
IMSI: 450061222639213
Phone Number: +821222639213
root@swi-m9x28-wp:~# cm sim
SIM card is inserted and unlocked (LE_SIM_READY)

Why can’t data be connected?

root@swi-m9x28-wp:~# cm data connect

Please help me use the usim of the LG Uplus news agency.

could you show logread -f when you get that failure?

Thank you for your reply.
Isn’t the current PDP type set to IPV4?

Hi,

Do you plan to use Octave or want to use your own SIM?
Point to note is that if you want to use Octave, you need to use Sierra SIM.
If you want to use your own SIM, then you need to build for Octave =0 and then deploy that on your unit.

Please provide more information on your use case so we can give more information and direction.

thanks,
Ashish

Thank you for telling me the important point.

What I’m curious about is this part you told me, “build it for Octave =0, then deploy it to your device.”
How do I do it?

I have added a Wiki page to the mangOH Git Hub that describes how to build the Legato apps for mangOH Yellow.
