Just tried it on mine and that works

MMI codes have never worked for me. Do you have 'auto blocker' turned on? Try turning it off and try again.

Few suggestions here

Dosent work on my S24 ultra, what network are you on

Got it working, if service mode (to check 4g 5g bands) does not work on Samsung s24 series then you need to turn off the auto blocker feature in the settings.

Thanks Robin 999
