Lollipop 4g/LTE band in Poland

Hi, after update my Moto x (xt1058 att ) to 5.1 i cant have my 4g. In 4.4.4 it was working like a charm. Is someone have a solution for Lte in EU?

AT&T LTE 9.7 " Tab cell phone caller and 4g/LTE signal switch?

Got my LTE version from AT&T version 2 days ago. Is there anyway to install the samsung caller app to make phone calls other than using hangouts or whatsapp ? Also trying to figure out to keep data but using just 4g instead of LTE to keep data down . On my edge + phone I can put a dialer code in to get to special settings . Anyway doing this ? Thank you! !!!
