Installing android marshmallow on q a galaxy s6 G920i

[AC Question]

Hi i was hoping to update my galaxy s6 G920I from Claro Puerto Rico(carrier) to Marshmallow. My galaxy is running android 5.1.1. Ive check and there are some sites that are giving the update download instructions for the G920I variant. But i was wondering if being from Claro(carrier) Puerto Rico could affect the update i mean could it work if i download the update and install it or it wont!? Also im completly stock no root whatsoever.. Thanks
