I have to agree with the TMO 5G in my areas it very nice to have I can watch movies with the 5G before they kept buffering everytime.
Their 5g here is “fair” as it says on their map lol. And one store manager wanted me to call tech support because my 5g phone I had produced speeds no better than their LTE. I’ll wait for them to implement more of their n41 etc. but I’m still buying an iPhone with them
