Yes, the phone comes with an overlay "T-Mobile", but it is not at all troublesome since installed apps can be uninstalled without problems! This leaves more than the logo "T-Mobile" (pink) appears ... second (!) When you turn the phone. So a truly insignificant disadvantage ... For the rest, GSM is entirely consistent with what is said in all the tests I was able to watch: fast, efficient, beautiful display and battery that holds a day without problems for use .. normal. (shorter if we spend our time watching movies on their smartphone ...) I recommend it the Galaxy Alpha!
