Has anyone gotten LTE running on the Verizon Note 8 using AT&T? I had to activate it with my Verizon sim to get to the home screen, after that I popped in an AT&T sim in and it worked but only gets HSDPA or H+ for data. I tried to toggle the mobile network settings and verified APNs but still doesn't get LTE or 4G. I tried all 3 operating settings and it seems to only get signal with Global mode (LTE / CDMA or LTE / GSM / UMTS doesn't get any signal at all).
I have the Verizon Note 8 running on AT&T and I get LTE. I'd like to give you some great tips but I just put my SIM in and it worked, previously I would have to enter the APN but not this time. Same with the S8 Plus I had for a few weeks, just pop the SIM card in and you're good to go. iPhones have been like this for a while now.
So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?

I got the Chinese version and I'm in the US. And I I have the straight talk T-Mobile sim and everything works like it is suppose to expect my internet. It says its 4g but it is very very slow. Any ideas?
So running the latest software it seems no need to flash firmware for carriers when you place an actual carrier sim in the splash screen and everything automatically switches to sim...I have a note 8 and a note 9 one cricket one metro since note 9 has band 71 I wanted to try metro in it and utilize that but ofcourse finding out metro locks service to imei unlike cricket does where any phone unlocked will work..but although I couldn't use my metro on my note 9 it did change splash screen and showed the wifi calling which I cant use wifi calling but i am able to hotspot again so that's the bonus for everyone on cricket needing hotspot again try popping in a tmobile or metro sim it holds even after restarting...correct me if I'm wrong on the firmware automatically switching cause the note 9 is a verizon bought phone and had been showing verizon splash screen....diagnose further when I buy new sim to tie note 9 to metro since they apparently pair sim and imei...

It's kind of new to me but I guess the take away for anyone is I've lost my hotspot capability on cricket when I switched to note 9 from note 8 cause changing the apn didn't work with new software like I did with note 8....and now i have regained that on note 9 which was bought through verizon also I'm able to utilize dialer codes again where I lost that too...so if your on cricket or something like that and lost those abilities then just pop in a metro or tmobile sim and restart phone then put your cricket sim back in and your good to go with hotspot and dialer codes again....I just wish cricket didn't whitelist phones capable of using volte where I could get that on my note 9 cause 3g calling has definitely went downhill with low to no coverage anymore on it...my real question is this everyone is talking about flashing the carrier csc to whatever carrier you going to so you have the best and all their perks just seems with latest updates there's no need for it like my note 9 has band 71 but while on verizon I'm sure they disable that band because it's not needed so it seems when you swap sims and forced to restart because new sim is detected and you put a tmobile sim in it automatically turns correct radio bands on for its network...correct or not because I want tmobile just need to know band 71 will be activated when I put a tmobile sim in this verizon bought note 9 and I'll be able to utilize their full network spectrum...cause metro by tmobile apparently only utilises band 2 and band 12 which cuts my coverage...sorry for the long read
