Yes it should work. The screen shouldn't be of any problems for different carriers. As long as the iPhone is a 4 or 4S generation.

This is an unlocked phone and as long as it one of the larger sim cards it will work. The only problem would be some of the smaller sim cards I know ATT was using with the latest Iphones.

No it will only work if its unlocked but since its for at&t you can't unless you have the att straight talk Sim card

As long as it is an iPhone 4 and uses a SIM card for service, it will work. Doesn't matter what color too.

Yes, I can use my ATT iphone SIM on GT-S7562L. GT-S7562L added 850 and 1900 MHz into original 2100MHz (of GT-S7652). Before you have to make it work, you have to set APN correctly as this phone is unlock and no setting. APN setting example, refer http://nerdynerdnerdz.com/blog/2011/07/23/att-apn-mms-settings-android/

It will work with ATT GSM (2g), 3g, but NOT ATT LTE since they only support band 17, 4, and 2. This international version only supports LTE 800(B20)/ 1800(B3)/ 2600(B7).

Yes, but only if the iphone 4's were originally on an AT&T plan (not Verizon, Sprint, etc.) If they were not originally on AT&T then you'll need to use a prepaid SIM from the plan company they were on....or unlock the phones.

As long as the iphone is factory unlocked it should work every where gsm phones (sim card phones) are used. I hope this answers your question.

If its an unlocked phone then yes it will work fine. I have a ATT and all I did was just insert MY sim card in and it worked perfectly in this phone. Its just that easy.

Yes. I ordered an iphone 2G and I had it working on ST. Since the iPhone is an AT&T phone it will connect. Mine took awhile to actually work. If you have a smaller SIM card you will need to order a Sim Card Converter from Amazon like I did

Hey man,It works all the gsm network around the world. I'm using this with a straight talk SIM card. Which actually shares AT&T; network across nationwide. So I can say "YES".Hope this answer helps you. Have a good day

Only if you have an Unlocked GSM version of the iphone 4 (I believe the AT&T; version of this phone is GSM, but you still would need to get it unlocked to accept this SIM card.)

Yes, it will work. When you purchase the sim just follow the instructions on back of the card. It turns your AT&T; iPhone into an AT&T; Go Phone. You will have to pay a monthly charge to add minutes. I purchased this item for my AT&T; iPhone and I love it!!!

Yes it works on iOS 7. In fact my iPhone 4 had problems with the latest version of the app under iOS6. Upgrading to iOS 7 fixed the problem.
