It would not surprise me to see kind of an opposite thing - such as other carriers selling phones where they purposefully turned off or hid settings for wi-fi calling, turning on hotspot and similar.. in which case if tmobile sold the same phone, then it would be a matter of them not turning off / hiding. Would be an interesting chart to show the things the various carriers had turned on / off... added / removed which similar phones.
