What are AT&T's LTE Bands?

My current understanding of the LTE bands is as follows:

 

**MAIN BAND

12 –700 MHz Lower B/C/A. This is a superset of band 17, so band 17 is not required if band 12 is available in the phone.

 

**ADDITIONAL CAPACITY

 2 – 1900 MHz PCS, provides bandwidth in many markets; 25 is a superset of band 2 but 25 is not required for some reason

 4 – 1700/2100 MHz AWS, provides bandwidth in many markets

 5 – 850 MHz CLR, the main band for areas lacking 700 lower B and/or C blocks

29 – 700 MHz Lower D/E – supplemental downlink bandwidth only; implemented in key markets

30 – 2300 MHz WCS, provides additional bandwidth in many markets

  

**OTHERS

40 – not sure if this has been implemented yet

66 – AWS, asymmetric favoring download speed, which is being implemented by AT&T now. Band 66 is a superset of band 4.

14 – Public Safety, 700MHz. Can also be used for commercial traffic but will have less priority. I do not believe it has been implemented yet, and don’t expect it matters if a phone bought today has it.

 

**QUESTION

 If I buy a Samsung unlocked Note 8, it will lack bands  29, 30, and 66 found in the AT&T version of the Note 8.   It appears that I would still get connection availability in all markets even without these 3 bands since they are used for additional capacity. Does someone know if this is true, and how widespread use of these 3 bands is?

What @GLIMMERMAN76 means is you will probably have to activate service in an ATT LTE phone then movie the SIM card to the Huawei.  The ATT phones IMEI will dummy in the system 

pretty much forever.  

Any ATT LTE enabled android will do as long as it’s not being used already. (Junked old android, cheap prepaid you stick in a drawer)

lizdance40 -

i think i understand now.... by starting with a SIM card in an AT&T phone, i conquer the IMEI issue permanently; it would be a one-time process.

 

possible fatal flaws would be?

- I forget to verify I can move a SIM card into the Huawei 20, before buying it.

- any comments about problems I might expect using the phone out of country (more common destinations like Canada, Europe, Hong Kong)? (...I learned a hard lesson in 2016 trying to take a Verizon-service iPhone4 to Canada.)

Verizon iphone 4 had no sim slot and couldn’t work on another carrier or a GSM carrier.  

Youre buying an unlocked, carrier free phone, not even in the same city, never mind ballpark.  

“Forget to verify SIM card...”.  Huh?   Just activate the correct size sim in an ATT phone.  Forgetting is not an option.

lizdance, would you say, then - after the discussion - that I can likely, without too much nuisance, make a Huawei 20 operate in the US on AT&T? that's my goal, to try to combine combine best camera and mobile phone.

 

thanks for your advice!

Last I check in the Los Angeles Metro, I was connecting to LTE Bands 17, 4, 2 and 30 in a 4:2:2:1 ratio.  I also ran around with a V phone with bands 2, 4 and 13 and got service, predictably  at a 1:1:0 ratio and LTE coverages was maybe 90%+.

 

 People running phones with LTE 2 and 4 only will do OK, at least in the LA metro area.

it depends on the phone with ATT...  Imported(not a model in the us line up) phones are a crapshoot when it comes to getting LTE.

If I can ask a similar question about an LG V20.  It's a US phone, but set up for TMo.  Here are the specs which differ slightly from AT&T's version....basically, it has the Euro band 20, but lacks AT&T's band 29 and 30.  I see band 12(700) here which I THINK is AT&T's main LTE band for data.  Does this mean I'm good to go?
