Maybe the problem was in mobile band/frequencies of your phone (the same model may have different specifications in each country that is sold). In Norway, LTE bands/frequencies are B3 (1800+), B7 (2600) and B20 (800 DD). T-Mobile USA uses B2 (1900 PCS), B4 (1700/2100 AWS 1), B12 (700 ac), B66 (1700/2100) and B71 (600) - see www.frequencycheck.com
