Don't go for South max Max HD just activate South max then Activate Max HD updated pack via selfcare either mobile or website and see that your max HD pack contains 40+channels as few Max HD obsolete pack activation is being done by CC/dealers/retailers that contains few channels less.
I activated via local dealer they activated a Max HD pack without Sony Espn HD.So it's advisable to not to go for 3 months ARP for Max HD as it is constantly updated and you can activate it on monthly basis or in ARP by yourselves after verifying you are getting at least 42 HD channels.Just go for South Max SD base pack ARP alone.
