I have two iPhone 8 Plus both are a1864 model but one is a Sprint phone and the other is a cricket and I want to swap the motherboards because of the condition of the housings but I’m concerned that there might be some network connectivity issues since they are different carries, Is it possible to swap the motherboards with no issues?
Yes, just be sure to keep the homebutton and Taptic with the mobo.
If both are 1804, I see no issues.
