Can i use my samsung galaxy s3 micro sim in a iphone 4s?

I'm wondering because i want to swap over to an iphone 4s thanks:-)

You can just swap them over (as long as iphone is not locked to a different network)

Of course, assuming your iphone isn't locked on a different carrier as the samsung.

Long answer short… Yup.

Doubt it will work

Yes
its will work

Yes, but it would depend on if the 4S is unlocked or locked to the same network to accept the SIM.

  • Will my iPhone 4s Micro-Sim work in a Samsung Galaxy S3? Some people have told me it won't work because the sim is made specifically for the iPhone but others have said it will work! I need 100% confirmation that it will definitely work.

  • What is a good phone, iPhone 5, Samsung Galaxy S2, or Samsung Galaxy S3? I need a new phone and I'm wondering which I should get. My friend is selling his GS2 for around 50 Bucks and I could possibly get an iPhone 5 or Galaxy S3. Can you tell me the prices with and without the plan. And for people that have these phones could you tell me how good it is and which carrier(Sprint, Verizon, At&T)?
