USSD Codes not working.

My phone is not working with the USSD codes ( e.g *111# , *121# ) on both the cellular networks JIO and Vodafone IN. It shows an error of Connection Problem or Invalid MMI code. Last time when i used them about 2 weeks ago they where working perfectly fine.
I tried restarting the phone several times, toggling the airplane mode on and off, etc.

Try to disable VoLTE and check again to pinpoint the culprit.

Dude , come on, get a life... It's a network level code for operator plans and offers. It's nothing to do with 2G or 3G or 4G or VoLTE enabled/disabled.
It not even required internet connection. Just a active network is sufficient.

I have a reason for that.

For me it's working. Even for the user raised query also it was worked.
And everything mentioned in internet , especially quora were not true. Please check the date in quora the question was raised and answered.
I guess , it's one of intellectual like you, who assumes know everything and think logically.
Irrespective of pre-paid or post-paid, the code should work and it's work for me and more of others also.
