It seems the XAA region for country specific codes is from the USA region.
There are a few issues with this.
1) it is highly likely you will not get any software updates as the phone is not in the region it was intended.
2) pay services may not work.
3) 5G services in the USA have different configuration in the mm wave frequencies and operation.
Is it new (to you). Did you buy it from backmarket or another reseller of used handsets ?
You may get better success by using google pay instead of samsung pay, but as I mention above... there may be other issues along the way.
In terms of reflashing the phone with a different firmware, I am not experienced in this and although it may be possible, it is not a task that is either recommended by samsung, or to be taken by a user without experience. It will also cause security issues with Samsung knox, and ruin any warranty the phone may have.
If it is possible the best course of action here is to return it to the retailer for an exchange / replacement.
