RM521G-GL issue

IoT Modules 5G Module
1

I cannot lock any bands on 5G SA and I cannot even enable 5G SA on my Quectel RM521F-GL module

First I run this:

AT+QNWPREFCFG="nr5g_band",66:71
OK

Then I run this to check:

AT+QNWPREFCFG="nr5g_band"
+QNWPREFCFG: "nr5g_band",0
OK

hi，
What is your current version?
