Xiaomi Mi 9 global/ATT compatibility

 I'm looking to upgrade my current unlocked Lumia 950 to something modern that doesn't cost an arm and a leg. 

 I've found the Xiami Mi 9 listed on Amazon for a great price. 

 will this service be fully compatible with the ATT network? Will LTE work?

No.  The global version lacks appropriate LTE bands for At&t. You will have no voice over LTE.   The Chinese version is still missing bands.  Neither will register as an LTE phone on AT&T.  

Currently the oneplus 7 does get VoLTE.  But the 1+ 6t had it until recently and now it doesn’t.   

This is a bad time to buy an android that At&t won’t recognize, you could wind up with no service.

 So ATT will only accept phones which they sell these days? I've used several different unlocked phones sporting  various OS in the past with no issues.

 

Do any of the other carriers currently accept these phones. I've been thinking of switching networks anyway, as ATT service has really dropped down the ladder in my area in the last couple of years. They used to be tops around here, but no more.

No, and not what I said.  And so have I, but things are going to change in 6 months.  

Not that it matters.  This particular brand often does not register as an LTE phone.

Its At&t or t-mobile.  Verizon and sprint will not except any of these phones and they won’t work if they did.  

 


3g will be shutting down over the next 18 months.  Phones made for the USA do work.  That phone is not made for the USA.   Pixel 3 series work almost fully, including WiFi calling.  One+ 7 is getting VoLTE.

Thank you for the help and speedy replies!!

 Is there a list or something to know what unlocked phones att will accept and if they will have full functionality?

 It depends on what you consider full functionality. The pixel three series is the only non-AT&T android that is anywhere near close. Pixel three and three XL get Wi-Fi calling perfectly. The built in pixel visual voicemail does not work, so you have to use AT&T’s visual voicemail app.     Best Buy sells a whole bunch of phones in there unlock phone department which work quite well on AT&T but will not have the same level of function that the pixel three does.    Nothing else is going to have Wi-Fi calling available.  

 Sony phones seem to be rather difficult,  I don’t know why other than Sony just does not want to work with American carriers anymore. So even though Sony sells phones through Best Buy unlocked Dept they may not be the best pick. There have been some problems with Motorola phones, as in the hotspot does not work on prepaid service. It seems to be solely a Motorola issue it’s not an AT&T exclusion. 

 I am using a one plus 6T,   I upgraded from a one plus 5T.

I had used the Mi 9 for two years on the ATT network. Yesterday I was told the phone won't work anymore when they remove the 3G network. It seems the phones get identified as a 3G phone and not as a 4G phone with the IMEI number. I am not sure why that is. It may still work on the T-Mobile network which I used to have. Unfortunately I get so signal at work and had to move to ATT. Its a great phone and very disappointed that I have to stop using it. The best part of the phone other than the general calling part is the picture and video quality of the camera. it's outstanding. I hope Xiaomi will fix the band compatibility with the US carriers soon so we can enjoy their amazing value phones in the US.

It is unlikely that any of the phones that are primarily made for Asia will ever be certified for use in the USA by Verizon or AT&T.

Being able to use your favorite device is understandable, @senakasinha!

 

As you're aware, AT&T plans to end service on 3G/3G HSPA+ wireless networks in February 2022, enabling our network to better accommodate next generation technologies and services.

 

Customers still using a 3G dependent device (including non-HD LTE devices) are encouraged to move to newer devices to ensure the best possible experience.

 

AT&T is using several approaches to accomplish moving customers to HD Voice capable devices that will work on the upgraded network. 4G and 5G devices use newer, stronger network connections that improve bandwidth, provide better audio and video quality and a better overall experience.

 

We hope this info is helpful!
