Can I put my current AT&T iPhone 4S sim card into an unlocked Sony Xperia Z LTE?

I want to get the sony xperia Z LTE unlocked so I can use it on the AT&T 4G LTE network. I love the Xperia Z's features, especially its cameras and waterproof capabilities. Also, would the Z1 work as well?

The SIM card will work with any unlocked phone so don't worry.

  • Will my iphone 4 sim card work in a sony xperia phone? I just got the iphone 4 on contract (yes stupid I know) but i'm going to buy a sony xperia phone to make up for it, I can't lost my contract though so can I put my iphone 4 sim card (the one on the contract) into a sony xperia prepaid phone?
  • Will an unlocked Sony Xperia Z2 run on AT&T in the US? I'm looking at buying an unlocked Sony Xperia Z2 to replace my current Iphone 4S. I was wondering if doing so would cause any complications, mainly because Sony hasn't released phones for US AT&T users. If I buy this phone internationally unlocked, will I be able to move my Iphone 4S sim card into it? Will the phone run AT&T coverage, particularly 4G LTE?
  • If I put a SIM card into an unlocked iPhone will it lock it to that phone? I recently received an unlocked iPhone 5s as a replacement from LifeProof. The point is, it says ATT unlocked. It says SIM required when I turn on the phone. I have a sim card but it's from my current service which I'm going to cancel so I don't know if there's a way to bypass the sim required. Or if I use my current sim card will I no longer be able to use another one?
  • I just purchased an iPhone 5s and I have a micro sim card but it's for a sony xperia? It doesn't seem to fit into the slot provided for iPhones so well, do I need to buy a new sim card?
