I have a Xiaomi poco, which i love, but when trying to get a plan from my phone company (Golan, in Israel) for use in the US, I was told it isn't supported. Can anyone verify this?

I presume I could still use my phone with WIFI, but I am reluctant to buy a phone package for cellular and data if the phone doesn't work in the US.

if you are more knowledgeable than I am on this topic (assume this is about everyone), can you suggest alternative ways to manage while in the US?

Thanks
