No help received with Nano sim

<p> I have struggled with 2 phones now I have purchased on contract that does not go onto the LTE network. I have gone to the Kolonade branch to help with no success. I have phoned customer care with no success in really do not know what I am paying for to get such bad service and no one can help me. This is really annoying. Seems like complaints do not not help. SAMSUNG S6 EDGE PLUS: ********** 045 . LG stylus 2: ********** 628. Both phones LTE capable but does not have the service?</p>
