"there is insufficient memory on the device"

Well my dad just bought some phone for me "x-touch ocean" and I've beeeeeen trying to download apps but it keeps saying "insufficient memory on the device" I tried deleting apps I already found in the phone but still.. I got a new memory card with nothing in it but it still says the same thing over and over.. I haven't downloaded anything at all by the way. And I tried to move apps to the memory card but none of them can be moved unfortunately. Please some one help #frustrated 15 year old #
