how to use a galaxy mega (us cellular) on straight talk

[marcushunter3]

I bought a Samsung galaxy off my home boy. and wanted to kno if I could use it with straight talk and also could I keep my old number

If both systems are GSM, you could use it, but once you get a ST card you'll get assigned a new phone number. The only way to keep your number is to have it assigned to Google Voice.
