Iphone 6s can use in Malaysia

Dear Communities Team,

Good day to you!

Kindly advise if I buy the iphone 6s from apple.com(US).Does the iphone work with Malaysia SIM card or carrier worldwide? Iphone 6s can be connected/supported with the Malaysia cellular network and WiFi? If I buy the iphone 6s to use in Malaysia, should I choose SIM FREE from apple.com(US)?

I'm looking forward to hearing from you.

Thank you.

Best regards,

Shirly
