The iPhone 12 is a 5G device, the first 5G iPhone. Carriers, including mine, will not allow a SIM card assigned to a 4G device to use the 5G frequencies or the many additional frequencies of the 12. Carriers do this because newer iPhones support many more frequencies than older iPhones and carriers do not want the newer iPhones hogging the limited frequencies and bandwidth only available to older iPhones. This is called network management. I learned about all of this when I ordered an iPhone 12 Mini and was sent a regular size iPhone 12. I was using an iPhone 7 at the time. I tried to return the 12 but was told the phone had to be activated first. This deactivated the SIM in my iPhone 7 and the cell phone store put the SIM from my 12 into my 7, which was a big mistake. Eventually, the cell phone store had to contact network control at the carrier to learn why my 12 could not be accepted for a return by the computer system. The returned phone had to have the original SIM because it was coded as a 5G SIM and a new SIM had to be installed in my 7 coded to the 4G network. So my 7 was deactivated again and I went to the cell phone store to swap SIM’s.
