Carrier Aggregation for AT&T

Anybody know how to make the T-Mobile N910T take advantage of AT&T's carrier aggregation? You know, like ban 4 + 17 or band 2 + 17 working as one?

Interested in this myself.
Sent from my SHIELD Tablet using XDA Free mobile app

So I did a little digging. These are the LTE bands and CA configurations the T-Mobile Note 4 can do. As you can see, it's mainly configured for T-Mobile's LTE network since AT&T's Band 17 (their main band) is not present in the CA list.

No help?

Look at the title of this forum. Look at the model of your phone. Doesn't look like a match to me.
Also, you cannot change the radio bands that a phone supports. You bought a phone that is incompatible with your service needs.

Just received my Blu Advance 5.5 HD, the Blu Help does not work. What can I do?

Carrier aggregation on Band 40 and Band 7 is disabled

So in my testing side by side, Appears there is currently no band 7 or Band 40 aggregation at all.
Any time i land on B7 or B40 Primary band, i loose 4G+ / LTE-A
on my older device, i get 3-28-40/7 3CA (which is the limit for that device) so i know the network is configured for it.
Provider hasn't said too much on it yet, Speaking to Huawei directly i've been told Band 7 and Band 40 are new so there is an incompatibility with Android 9.
Anyone else had issues with this or other bands missing CA?

No problem with carrier aggregation on LTE Band 7 on Telekom Germany.

Can US S20FE CSC changed to EU/UK version?

Hi all thanks for looking into my question. I need the band n78 for 5G so I wonder if changing the CSC can do the trick. Are there any other ways
that this can be achieved?

I doubt it would fix your problem, I've had a quick read of Samsung forums,

available frequency bands are related to hardware not just software. if you're in the US having European firmware isn't gonna help you, more likely you'll also less LTE reception on top.
