Yes. The iPhone 4 has the micro sim as we'll. even if it were a nano sim. You can get an adapter or just place it precisely on the metal part.

Yes, i bought this sim card and its working fine with my phone. Have 3G almost everywhere and with a good speed at AT&T; network.

Most likely yes but you should confirm with AT&T; as there are multiple SIM card sizes based on the phone manufacturer and operating system.

That was exactly what I used, an AT&T; unlocked iphone 4. I put in this SIM card while in US and immediately got the roaming signal (AT&T; as roaming carier in US) and welcome text message in Chinese. It worked great in China.

I had a sim suitable for an iphone 4 and it all worked well for me. I suggest you order well in advance if you want delivery to your home country and to take it with you to the US. Alternatively, have it delivered to a US address. You can activate the card any time in the US. Before purchasing, be sure that Ready Sim does cover the area of the US in which you will be using your phone.

No, this works in any phone that takes a FULL SIZE SIM card (it needs to be cut to fit into the iPhone 4)and is on the AT&T; network or unlocked.

Only if you're a at&t contract customer . If your sim is a different size you'll have to take it to a at&t store or retailer with at&t to in stall the sim card they will also need phone serial & imei numbers

the 3G network of AT&T; is WCDMA, and this phone support WCDMA, so it will still work with your SIM card

Yes it will work because it is an At&t phone. Just switch out the Sim card and place into new phone. Make sure it is a micro sim.

The kind of SIM card that takes if it is an AT&T phone then you may have to use an AT&T SIM card.

This model is unlocked, so yes it should work with AT&T.; I've used it with many carriers in a couple countries with no issues. BUT THIS PHONE IS TERRIBLE, IS THE WORST I'VE HAD, IT IS NOT RELIABLE AT ALL, IS REALLY SLOW, CRASHES A LOT, HAS ISSUES WITH THE SCREEN BRIGHTNESS, VIBRATING, SENSORS, BATTERY, I DON'T RECOMMEND IT AT ALL.

Yes, because the SIM card pack includes micro size SIM card which is required by iPhone 4.

Hello, to my knowledge it should work with an existing contract. I completed my contract and have purchased a new phone that is under contract so there aren't any holds or anything on this phone; however, I'm not sure what type of activation fee AT&T; will charge. The iPhone 4s uses a Micro-sim card.

I have an AT&T; iPhone 4S and on the right side middle is the SIM card slot. This duel sim has an adaptor that goes into this slot....so if your iPhone 4 does not have a sim slot this case will not work. So let me know if you need more info. Anthony�

I am almost positive that you will be able to use that SIM card. I was told that any At&T card can work in any At&T phone. However, if the one phone is not 3g, then you will have some limitations. Since you are going from 3g to 3g, you should be ok. I was ok when I switched over to this phone. I had an intermediate phone that was AT&T that was not 3g, i could not make international phone calls. So, I got this Pantech and am getting international phone call capability.
