I purchased a 12 pro in Germany with Telekom as my carrier . I’m in the US for about a month before I move to another overseas assignment and to my dismay, I can not use a prepaid SIM (tried Verizon and T-Mobile) Most companies are saying the phone is not compatible. Is my iphone now useless?
iPhone 12
Is your iPhone 12 Locked to Telekom? Do you know? If this is the case then the iPhone 12 will not work with other carriers in the US or anywhere else. I recommend that you contact Telekom and see whether they would allow you to use the iPhone with other international carriers.

The original poster states that the iPhone is an iPhone 12 Pro. The iPhone 12 Pro has a single model number that supports all US carriers. This includes support for both GSM and CDMA networks, as well as 4G LTE and 5G bands.

When Apple releases new devices, there are multiple models of each. Within those models, there are subtle differences.
Different carriers do work on different frequencies, and giving a generalization, we will go with GSM and CDMA/GSM. When a GSM only device is unlocked, it can only be moved to other GSM networks. When a CDMA/GSM phone is unlocked, it can be taken to most any other carrier. So it is entirely possible you had a GSM only device and you are attempting to move into a CDMA network (Verizon).
I spoke with Telekom customer service and they stated they’re phones are automatically unlocked and the reason that the phones may not work is because of a difference in frequency that the different countries use. They put in a ticket with tech support. Have you heard of such a thing?
