Hi @Ajith5,
Sorry to hear about the trouble you are having with your phone.
To my knowledge you should be able to deactivate one of your SIM-cards without it affecting the other SIM-card. Do you have two other SIM-cards that you can try inserting in your phone? Let me know if you experience the same behaviour then as well.
I would also recommend that you try rebooting your phone to safe mode, this will allow us to rule out any third party apps being behind this.
Let me know how it goes!
