Jio 5G network not support to your's device due to it's out of India variant. So please use only Airtel 5G network. If you like please accept as a solution it's help to others users also,click on 3dots in my reply section and click on accept solution . Thanks.
At present, Jio 5G services are not compatible with Samsung devices purchased from the United States. However, if you have good coverage of Airtel 5G in your area, you can use an Airtel SIM card to access 5G services on your device. It is important to note that Samsung restricts network bands by region, which can be a limiting factor for users. In contrast, if you had purchased an Apple device or another Android device from another country, Jio 5G services would work seamlessly. The reasons behind Samsung's decision to restrict network bands are not entirely clear.
I read this response more like. It's your fault trusting Samsung and you have to suffer and regret buying samsung mobile which is incapable of handling 5G properly.
