One Reply to “Samsung Galaxy S5 System Software Not Authorized By AT&T Issue & Other Related Problems”

  1. I have within the last week ported my 2 Verizon galaxy S5 phones to AT&T, I have been to the corporate store 7 times and the AT&T chat 6 times, The main problem I am having is I am within a AT&T 4glte signal area, my signal is H or H+ this is within 7 miles of the AT&T tower, when I get within 2 miles of the tower the signal goes to 4glte, also at the AT&T store, after all the analysis they tell me the Verizon frequency is not compatable with AT&T and my only option is to buy new phones, for me this does not pass the common sense test,
    Can you help me ?
