Can I use the 3 digit of MNC?

Q/A
#1

Hello,

I’m using free5gc v3.0.5, and I think I’d like to change the number of PLMN.
Can I use the 3 digit of MNC?

I tried to change the config files of amf, ausf, n3iwf, nrf, and nssf from mcc:208 mnc:93 to mcc:208 mnc :933.
I also changed the config files of UERANSIM.

As this change, the connection of gnb successed, but the connection of ue didn’t success.
Then, AMF and UDM showed the problems.
In the log of UDM, there was a sentence like the following.

Preformatted text`suciPart [suci 0 208 933 0000 0 0 0000000010]

I registered the UE as imsi-208933000000001, but it was written as 0000000010.

Because of this, I wonder that the cause of this problem is that MSIN is fixed to 10 digit although it wants to be 9 digit when mnc is 3 digit.
Does anyone know some ways to use the 3 digit of mnc?

For reference, I attached the UDM log when mnc is 2 digits and 3 digits.

Thank you for your help.

Hello.

I could solve this question.
This issue was caused by UERANSIM and it was resolved by using the latest version of UERANSIM (v3.2.6).
Thank you for your cooperation.
