A family member gifted me a Galaxy S4, however it is the SGH-M919. I currently live in Europe and 3G bands in my region are GSM 900/1800. At the moment I can't access 3G and any other type of data for that matter (LTE is not supported here). Is there a way to change T-mobile 950 and 1900 bands to my region ones?
Thanks for taking your time to answer
