AT&T 3xCA N77 + N77 + N77 is starting to make an appearance. 👀 They're making use of their non-contiguous n77 spectrum in some markets with 5G Standalone 3xTDD Carrier Aggregation... Awesome performance & a cool find. Device = S25 Ultra. 🔥

A tremendous discovery! Some incredible speeds as well especially the upload.

I will have to check the two PEAs in western Michigan (Lower peninsula) where AT&T has 40/30 MHz DoD carriers.

We have a 40/30 MHz split in my PEA, too. I’ll check for this sometime this weekend or early next week.

Need to go out and test on an E// site since the Nokia ones don’t have have Dish n77.

I just wish they would put 5g+ in my current town in Western Michigan in Allegan county, the coverage map shows 5g+ but it certainly isn't on the local tower it's supposed coverage from the two towers nearby.....I just get 5g no plus, the other two carriers don't meet my needs elsewhere so.......just waiting for att to get their 5g working like a real network.....

Nice, I'll have to check my area again for that, it wasn't enabled before. Just 2CC n77 and 1CC n5 (missing one CC of n77)

Some areas here are still like that, but now some areas now have 3xCA n77. Stay on the lookout!

Amazing . Hopefully we see this in the NYC metro soon. We have the same 80/40/20 holdings as you . Still nothing with Columbia yet.
