iphone se2020 what happens if I temp switch sim then switch back?
 

I currently have verizon prepaid and want to temp switch to one of the prepaid services that allow the use of att to test the signal at my house. When I'm done and I put the verizon sim back in, will I have to change anything or will it just go back to verizon as before? Thanks BGC
