I don't think the Ultra Capacity logo is something Samsung can't add since it's a T-Mobile feature.. it would have to be T-Mobile branded device to get the UC.
T mobile said it can be added since it's a signal thing. It's like the UWB on Verizon if the phone supports it and your area has it then it can be used. If it was a carrier only thing with carrier branded phones it wouldn't last. People now are choosing a sim free unlocked phone as kore freedom
Right. Like AT&T phony 5Ge symbol🙄 I'm glad I have an unlocked variant now. At first I was upset. I lost wifi calling but then got it back. Everything is better this way. No bloatware. I have 512gb but STILL I don't need nonsense apps I can't remove. That's Apple behavior.
