Can a unlocked sprint iphone 5 work with simple mobile?

If so, how do you connect it?

I don't believe so because sprint uses a CDMA signal and the simple mobile carrier provides signal from tmobile which is a GSM signal. A sprint iphone doesn't have the antenna to read gsm signal i believe.

Here's what you can do, go online on craigslist or ebay classified and post your iphone up for trade for an at&t iphone 5, the same model, same exact everything.once you trade your phone for an At&t iphone 5
