Hi John, if it is an unlocked or AT&T; phone, it will work straight out of the box.

It should. My Consumer cellular sim card did in both the 3gs and my current iphone 4.

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.

You would have to check with your service provider or with Samsung. AT&T; provided a new sim when I signed up with them for data service.

After you activate the sim card online or by calling an att rep.. They will assign your sim a number.. Works perfectly!!

If your SIM comes from an iPhone 4 or 4S (or an earlier model) it will not work. However, it took me ten minutes at an AT&T store to get a compatible SIM for my 5S and to get it assigned to my phone number.

Yes, you can use your At&t; sim card in it. My works perfect with any sim card. Just make sure the phone is unlock.

Yes- the phone works with other SIM cards. I use Straight Talk,but it runs off of AT&T; towers.As long as the provider has service in your area, you should be good to go!

You dont have to activate the plan ... as soon as you put the sim in and register it should start working .. if it doesnt work ... return the sim

Yes, you can put your SIM card into any at&t; phone. This phone however gives me trouble, sometimes the touch screen does not work.

Just take the sim card to your preferred carrier and ask them to activate it for you. These sim cards are for pre-paid plans anyways...If you're going to AT&T; they have a site to activate the card. Follow the instructions carefully and you should be fine.

I don't think so seeing that it is a T-Mobile sim card. You should try and speak to an AT&T; customer service rep and ask them but I doubt it.

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!!!

The phone will work as good as if you were using a AT&T; sim card. Some pre-installed apps will not work but Windows phone store and its apps will be fully available when you update the phone.
