SD card not recognized

[AC Question]

I have recently bought a Huawei G6-U10 mobile, Android version 4.3
I had a Nokia X3-02 with a 2 GB Micro SD card (SD-CO2G that's what's written on it). When I tried to put it in the Huawei mobile it didn't recognize it.
When I checked in the settings, it said (Insert an SD card for mounting)

if the SD Card is blank, try reformatting it.
