Device Software Update: Samsung Galaxy S5 Active (SM-G870A)
I have a used unlocked S5A that I'd like to upgrade to marshmallow. I purchased a prepaid talk and text plan and sim which is activated and paid for. Requests to update the software are still met with "your software is up to date". It's at 5.1.1. Do I have to be in an area of the US with an active phone connection as well as a wireless data connection. My plan has no data. I live in Canada. I have a cottage in Point Roberts which has a very weak ATT cell service although it is OK for messaging. I thought I knew what the base requirements are for updating. What am I missing?
