Sir, I am telling about that handset which is physically tested with CA.
As per wikipedia list, all mentioned handset don’t support CA physically. For example none of the xiaomi and sony phones support CA in india physically. Even one plus 3/3t is mentioned but not supporting physically. Htc a9 mentioned but not supporting, only htc 10 supported. Htc u11 I never used or any of my relative didn’t used, so i don’t have idea. I never used samsung phone, so cann’t comment about any model of samsung. Yesterday I bought a9 pro after taking advice from you itself and it is working great. I just want to say sir, many of the handset that should support CA , actually not supporting physically in india..
