Purchase Bad esn smartphone samsung galaxy series. Is it worth it?

Question

Android

There are galaxy s9 offers at a very good price but with a bad contract. There is very little information on the network, but many write that this will not affect the work in our networks in any way. And one more thing, that only Verizon does not have a lock from the factory. Someone will share experience and maybe knows something for operators besides Verizon?
