It's not the problem with 5gI'm also facing the same issue. Mine is also S9110(Hong Kong version). The same sim offers 5g in my iPhone. Contacted Samsung support. It was informed that an update will be provided to enable 5g in India for overseas mode...

Hi, I have purchased Samsung S23 from UAE (told as international version). I'm unable to use jio 5g in India in my phone. It says the phone is not 5g ready
