Are Sprint Iphone 4s unlocked GSM & GMCA?

I bought recently a sprint iphone 4s but i need it to unlock to use it with t mobile, i read something it says the come unlocked but i'm not sure, are they unlocked?

Its not SIM card capable so it can't be used with t-mobile.

The 4S SIM card feature can't be used with carriers in the United States. On;y with GSM carriers outside the US.

They do come unlocked. Just not for US carriers. You can only use it with Sprint in the US. You probably should have looked into this before you bought the phone.

And T-Mobile is apparently adding the iPhone to its line in the US in a few months.

  • What all do I need to do to upgrade from my iPhone 4 to a GSM unlocked iPhone 5S? Is it simply as easy as removing the sim card from the old phone and putting it in the unlocked 5S? Do I need to contact AT&T and let them know I've done anything? Just ordered the unlocked upgraded phone, and am worried IIm going to have to go through a whole ordeal.
  • Unlocked IPhone 5. Can be ported to one GSM provider but not another. Why? My friend in South Africa got an AT&T model of Iphone5. It is now unlocked and has been ported to one of his providers. He doesn't like the data rates and wanted it on either "Cell C" or "8TA" (which is Telecom Mobile) Both are GSM providers I believe. So why can the phone be ported to one GSM provider, but not the other? Should the Iphone 5 be possible unlocked in a different fashion? he assures me, it should work on the other networks in SA.
