HTC one m9 no service

Hi, my new htc one m9 has no service, no signal bar on the top of screen and next to that has a sim with a ''?'' on it, can't ,make or receive calls or connect to internet, when i buy a new phone(usually samsung) i usually put my sim and inmmediately it shows the signal bar idk why htc is different, already tried to add manual access point names, searched for network operator and they do show up but after about 3mins loading it replies> ''this sim cannot connect to this network'' or something similar, i've spent about 2 hours looking for possible fix to no avail, as prefered network the m9 has Global, LTE/CDMA and LTE/GSM/UMTS, i picked the last one because is the only 1 that allows me to open gsm options and try to add an operator, any help greatly appreciated
