Recieved "device does not work on our network" message on new device

Is this a problem? I got a Redmagic 9 Pro, and received the "Hi It's AT&T. The device you tried to activate does not work on our network. We're here to help." text on my new device. Is this device actually not supported, or was it some fluke. Is it only partially supported?

@horuslorus  Apparently the custom Nubia OS only supports 3 out of 5 bands on AT&T and there are apparent compatibility issues with AT&T's HD Voice (VoLTE). It doesn't appear that Nubia tested their phone for compatibility on AT&T's network and submitted that information to AT&T.

They likely won’t allow you to activate the SIM for using the phone with AT&T.

That could only be temporary. AT&T did have a whitelist of phone models whose mfrs had submitted their compatibility testing to AT&T but I don't know how current that list is anymore. My guess is that the model of Nubia  that you have did not submit their certification so connectivity to AT&T will eventually stop, or the connection will become very slow as to not be very useful. 

The phone is basically a gaming phone so it's anybody's guess.

Ok, so basically if I don't mind losing some coverage. I'll be fine? I'm not super knowledgeable about how cell networks work.

I already made a call with it and sent a few texts. So I'm still in the unsure part of this.

That brand didn't test for functionality.  Most likely will not have voice service and maybe excluded from data as well. Either change the phone or change the network

AT&T has an IMEI check, as well as a list of devices that have been tested to work.  The device list may not be current, but there are brands that are excluded and probably always will be.

How long might that take, I'll update this after that time to say whether or not the phone is still working with the network.

The device is not supported on Verizon network, the review I read stated they used T-Mobile for all their testing and had not problems….

thus the conclusion is change to provider to T-Mobile or change the device to what works on ATT such as Samsung Galaxy S23, Google Pixel 8, IPhone 15 Pro Max
