S25 the Failed Expensive phone that can not make Cellular calls

[Members_FvsAJLk]

My S25 having terrible Network Signal and I can not call anyone, nor anyone can call me via the Cellular.

Is this phone a failed phone like many Samsungs and I should seek to get some Xiaomi or OnePlus phone?

Yes, change your mobile network from 5G to 4G.

I don't think that that is Samsung fault. More operator problem. 

Try exchanging SIM card for newer.

I see that the op has replied in another post with the same problem saying that they have also tried flashing different region firmware to resolve it, while I'm guessing that this in itself voids the warranty, the only options left are to flash back to the official region firmware and take back the phone to the store they got it from,  or to just buy that xiaomi/oneplus 🤔
