so you have the most updated modem OS

ATM here is a list of build date by known routers:

- VDFIT B07 (AT1) -> April 2021
- VDFIT F1 B01 (AT2) -> June 2021
- VDFDE B07 (AT2) -> May 2021
- TMOBPL B01 -> October 2021

we don't know.. ULCA seems enabled on all builds
Can you try cell lock?

pls share also this command's output:

adb shell cfg show | grep voice_work_type

want to see if you modem is in CS or VOIP mode

On all channels ? Especially 132...

tomorrow I can try lock Give me a command and tomorrow I check pci and eafcrn and do it

Yes I talk. Work great

incoming only I didn't try call

You mean  adb shell cat /etc/rcS-zte-after-modem
?

On my VDFDE i also don't have voice_work_type in cfg

And also brifly tried ZLOCKCELL .... And for me it not working.... On MF286D when i do it  , it was set as primary band , but now not at all:

AT+ZLOCKCELL?
+ZLOCKCELL: 1599, 100

AT+ZCAINFO?
+ZCAINFO: 262, 20, 59100, 6350, 10.0;          100, 1, 3, 1599, 10.0;          367, 1, 1, 225, 15.0;          118, 1, 7, 3175, 15.0;
OK

Next case:

AT+ZLOCKCELL?
+ZLOCKCELL: 3175, 118
OK

AT+ZCAINFO?
+ZCAINFO: 262, 20, 59100, 6350, 10.0;          100, 1, 3, 1599, 10.0;          367, 1, 1, 225, 15.0;          118, 1, 7, 3175, 15.0;
OK

Tomorrow now I have no access to router.Could you write me whan exaclty do this script? Interferes with modem firmware?

Yes I doesn’t work. But pci_lock file is created in the EFS, also modem should look at this file. May be there is some other file that disable this feature
