This was my Galaxy S10 phone before I upgraded. The phone works perfectly and is unlocked. This model was designed for US carriers and supports 4G LTE, CDMA, and GSM only. Phone has been in a rugged case all it's life, and only has some very slight scratches on the glass, which you can't really notice once the screen turns on. No cracks, dents, or replacement parts. Only thing to note is that the battery is getting older (I would guess it's around 50% of it's original capacity).
