iphone 13 mini support 5G n48 band

I am testing various UE/CPEs for 5G band n48 (3550 to 3700 mhz). The spec for iphone13 mini A2481 says that n48 is supported. However the unlocked device I have is not working (no rach) with the gnb. Other CPE devices are able to attach with my gnb so I do not suspect it is a RAN issue. Does the iphone 13 mini actually support n48?
