I switched October 13th from AT&t to T-Mobile. I switched over with a Sony xz-2. Which has been 12 but is not certified with T-Mobile definitely does not have band 71. Seems to work but when I do speed test it seems pretty slow on the speed test. Good morning at the speedtest.net app is working or not.
I did bring over a note 8 which has band 12 and it certified on T-Mobile, have not test that one out fully yet.
I was just wondering because I have full signal on my Sony xz-2 but it's still only pulling down about two to three megabits download. Where I am at currently. Which is sylmar California.
Any helpful insights would be greatly appreciated.
