Gsi on redmi note 10 5g camellian no service

hi. first, thank you for the work of iode gsi.

i flashed it successfully, can boot, but I do not have any service. i tried to help myself using ai, but there is no definitive answer yet, and want help from a human. how to get mobile service to work in iode gsi? is there any method? I read something about baseband or nv files, but I can not achieve that myself.
