No it has to be unlocked
The Apple iPhone is generally locked to the phone company selling them. You cannot swap SIM cards.
If your 3GS is locked, you can't insert a SIM card.
Provided its a micro sim and the handset is not locked and the provider actually provides a service for the iPhone 4S then there should be no problem.

If it's already locked on their network - yes. If it's on another carrier's network - no.
If you bought an iPhone 5s from eBay and it is locked with a fingerprint lock, it will not be possible to unlock it if you do not have the Apple account.
Of course, the iPhone 3G and/or the original iPhone will take any normal sim card; the 3G iPhone will take the 3G sim as well.
on my iphone 3g screen is locked so it can not spin anymore. How do I open it to spin again. thank you
Yes. The hack can bypasses iCloud security system for a locked iPhone 5.
I had a iPhone 4s, Verizon carrier but i unlocked it for my friend so she can use it in different carrier. However, she told me that she can not use it because it is still locked. Even technical unlocker person can't unlock that cellphone. She gave me $200 on april but I feel like she is lying and want her money back. Before when i gave her a cellphone. Verizon name disappeared on the screen when service center told me it was unlocked. Would iPhone 4s still be locked? And i didn't take out my old sim card so would it work if she put hers?
If the rotation is locked, unlock it! Otherwise send it to Apple for repairing.
double tap the home button while the iphone is locked
