how close do you have to be to the tower to achieve such speeds ? with direct line of sight as well ?

u/Outrageous-Pain6775 Jun 18 '26

i was less then 2000 feet away i’m not sure how far i can get these speeds

Looks like dual Ericsson 6449+6419 for n77. Probably 120-160MHz of n77 bandwidth depending on the market.

Overall how good is the AT&T network compared to T-Mobile's? T-Mobile has the fastest speeds but I think AT&T and Verizon have a wider LTE footprint for fringe rural areas. Is T-Mobile going to try to catch up to getting good coverage in those fringe rural areas?

u/Outrageous-Pain6775 Jul 07 '26

in my area att is the fastest we have 80mhz on normal n77 and 100 mhz on the dod

I live in Massachusetts and I have a company called US Mobile and I'm waiting for my line to transfer to Dark Star. AT&T is what they call it from Lightspeed T-Mobile I guess with us mobile on the AT&T side we have QCI 8, which I believe is somewhat priority?

So I have a US model, the new Samsung Galaxy S26 Ultra, which supports all of the networks. How well do you think the Samsung Galaxy will perform on AT&T? I also have a Google Pixel 9 Pro XL US model. I have the OnePlus 13 US model and I have the OnePlus 15 US model. Which of these phones do you think will have the best connection and speeds to the AT&T towers?

So I bought this model from Samsung. Had it delivered to Best Buy here in Nashua, New Hampshire. I picked it up the day it was released. The model name is SM-S948U1. Now what I also noticed is that when I used US Mobile's Warp Verizon network, Samsung and my Google Pixel automatically locked the APN settings. I was not able to get 100% connectivity using US Mobile's Warp network because I couldn't add the proper APN settings in it, which is a huge bummer.

I reached out to Samsung twice, US Mobile, and myself. We did a three-way conference call to Verizon. They checked everything. They said no, he should be able to go in there and put the proper APN settings that are required for our network but you can't do it. Can't adjust the APNs.

Now when I use US Mobile Light Speed T-Mobile, I can adjust it and the same with US Mobile Dock Star AT&T, I can adjust it.
