By SD card I'm presuming you mean a memory card, It shouldn't matter if you have one or not as long as you have enough space/memory on your phone, you download the songs the same as you would with one, that can either be off vodafone live or by bluetooth etc.
the phrase mp3 mobile phones means that a phone is capable of playing mp3 music files. This may require you to purchase a seperate memory card for your phone as your phone may not have enough memory to store the files.
You need to be more specific, if you mean a phone, camera or games console style sandisk like memory card, then you need to find the files in My computer, or the mac equivilant

The quickest way would be to insert microSD card into an SD adapter, plug it into some card reader, then stick it into the comp and use regular "format it" command from whitin windows explorer (right click onto memory card and select format...)
