I have t-mobile for a carrier. I want to take advantage of the Samsung trade-in offer - because I can get $600 back toward a new S20. I'm trying to decide if I want to get the unlocked or the T-Mobile version. I read some of the T-Mobile forums about the S10. Things said in the forum were that the speed was about the same for both versions. However, the unlocked version didn't have the T-Mobile video calling (which we use with grandkids). However, when you bought the phone from Samsung, it was sometimes a big pain to get it unlocked.
I called Samsung for more info. They said that the unlocked phone had video calling, but not the T-Mobile WIFI calling (which I sometimes use when traveling.)
Do you all know anything about those features?
