Will an iPhone 5 locked with t-mobile work with a simple mobile SIM card?

I have a simple mobile SIM card and wanted to know if I could cut it down to fit my iphone 5 bought from t-mobile

Yes you can because simple mobile is powered by tmibile towers. If it were using AT&T towers then you would of need to unlock it.

Yes, you can but you need to unlock the phone first before you can use SimpleMobile SIM in it. Make sure you've the phone unlocked. Check online for unlocking the T-Mobile iPhone 5.
