Hrmmmm...4g sim or lte sim?

So far I have seen the old 3g sim...4g and the new lte sim.

I have the 4g sim out of my infuse. Best buy had none of the new lte Sims ...but the phone did connect to lte so we thought all was well.

I wonder if it does make a difference.

It almost seems that the 3g radio is being "lazy" and not waking immediately.


Download the app log this and get some logs when this occurs. I am on the road for the next few hours but may be able to look at it when we get to the hotel.

Log the key word "radio" or "connect" "connection"

This could be an issue. I live in the middle of nowhere. I expected to not have LTE here

Apparently, depending on where I am located on my property, I completely lose data connectivity while the phone switches from the LTE radio and the 3g radio

A few occurrences it corrected itself. At least once I had to turn on airplane mode and then turn it off and data connectivity was restored

Please post if you find similar instances

Same problem. I'm in maryland, Baltimore has LTE, but even when I'm in baltimore I can't get data to work (speed test app will ping but that it).

In Owings Mills MD its finicky, I have to restart the phone a lot. In Carroll county, its only hspa, but data continuously works.

Seems like a coverage issue when I'm bouncing between umts, hspa and LTE.

VERY frustrating :mad:

I've got the same problem, data dies a lot, just goes unresponsive in certain geographical areas (not in the middle of nowhere, and other AT&T customers get 3g fine)

How can you tell if the sim is LTE. In baltimore my phone says its on LTE, but the data doesn't work. In Owings Mills MD its in and out.

My sim doesnt say 3g or LTE, just a bunch of numbers.

The ATT rep at my local store swapped my SIM out that BB had put in. He said the LTE ones have green on them...the only visable difference.

Hmm, they gave me a new SIM, but maybe the guy didnt know what he was doing (as he wasnt aware the phone had just came out).


I see no green on my sim, would you mind taking a pic of yours?

Thanks!

Let's see if the green shows through in this picture. You should see white at the top of card and orange/green at the bottom of card.
