Self-Cut Micro Sim not detected? topic

Hi all! Recently got myself an LG LG2 and its a very good phone. So I did a bit of DIY and cut my MiniSim into a Micro Sim and the LG G2 wont detect the newly cut microsim card. However, if i align the contacts properly it still works perfectly on my old ace 2. Does this mean a bad cut, and do I have to do a replacement? Or does it have to do with my phone.

Besides that are there any solutions to this problem
