Need to Verify some settings T-Mobile & X-3000

Hey Everyone. I have read through a lot of advice on the different internet sites and just wanted to see if what I’m doing on the Spitz X-3000 is going to work. I plan on using the sim card from my TMHI 5G gateway in the Spitz. I have changed the IMEI to match the TMHI gateway. Are there any other settings I need to input prior to trying this setup? Thanks for any and all help.

If you already got your imei set your apn to fbb.home and let it rip
