SIM card is not getting detected

I have Motorola Moto E -1st Gen

One fine day suddenly the display start showing NO SIM CARD. When I used the same Sim card in other mobile its working. So, I am pretty much sure there is something wrong with my phone SIM slots.

I went to authorized service center, but didnt got any help.

Can anyone have idea.
