AT&T and Verizon have begun limiting which manufacturers are even allowed on their network. TMobile will allow more manufactures, but less popular hardware support.
If you can change IMEI to trick AT&T or Verizon to think you are using an iPhone or something, that might work, though you can get kicked off your cell plan for changing IMEI...
EDIT: Apologies for reviving an old thread- just figured I would put this here. Xiaomi won't even be able to connect to voice or data on anything but TMobile since Feb '22. I hate corporations.

What I did is use an IMEI randomizer to simulate a pixel 5. Put those into the file using notepad (two different ones since I have 2 sim slots). Loaded the file onto a usb thumber and plugged it into the usb interface of the unit. My unit popped up a message saying “imei changed”. Then after a reboot the new IMEI was in the unit settings. Plugged in my USMobile sim card and it showed up on my account to register.
My unit is an FYT with vendor ID=1.
Us mobile uses the t-mobile and Verizon networks. The Verizon sim got no signal but the t-mobile one had all the bars.2
make a text file named "IMEI0" (no extension)
edit it to put in two IMEI values that are valid and compatible with your provider. (one for each SIM slot)
copy to USB stick
plug it in
Some people activate SIM on a different device, but some providers check (I moved mu SIM to a DEL Laptop and got a message from Verizon that it was in a new device)1So it appears all of the Big 3 in the U.S. utilize FDD-LTE Band 2 - but this begs the question why my previously-purchased new cards that should have worked on the AT&T network (one from Straight Talk and one direct from AT&T) would not work in my older unit.
Do I have to somehow make sure the card I purchase is specifically for that band, or does any AT&T 4G LTE (non 5G) card, work on ALL of the AT&T bands?
Forgive me if I'm asking really dumb questions here - all this compatibility of various cellular networks stuff has me spinning in circles.1First thing is to put in your SIM card and see if you get bars.
I had two cards, one for T-mobile and one for Verizon. Only the T-mobile had bars.
If you don't get bars, you don't have a network and nothing else will work.
My radio info read the SIM card and told me all the deets on the network provider.
I don't have a T'eyes unit just a generic FYT unit, and the "magic file" is just a text file named IMEI0 with 2 lines for IMEI numbers.1
Thanks!
