You cannot use a different country's SIM card in an AT&T iPhone 4.  All iPhones sold by AT&T are locked to the AT&T network.  Any methods to get around those locks cannot be discussed here.  You will either have to enable international roaming and buy an international roaming plan, or you will have to use a different phone.

As the poster above said (and as is widely reported everywhere) AT&T/US iPhones are SIM Locked to AT&T. They always have been, always will be. You'll need to buy an unlocked world phone for use with other sims.

Just back from that part of the world..

 

Had a couple iPhones on the trip.

 

One of them had the AT&T International Data Roaming plan, 20MB.  3 days, 20MB should be enough...

 

Don't think so, especially if you're lost and use the map app.

 

Next time if we don't get a local SIM (for the unlocked AT&T iPhones) we'll get a much higher data plan.

 

The 20MB plan is close to useless..

And just so we're clear, there is no current legitimate way to unlock the iPhone through AT&T or Apple.  Any third-party methods undertaken to unlock iPhones run the risk of voiding your warranty, and they cannot be discussed in this forum.

And just so we're clear, one of my unlocked (AT&T) iPhone 4 died.

Took it to the Apple Genius Bar.

Phone replaced, no questions asked.

Of course, that was my single experience at one Apple store.

They do not have to replace a Jailbroken phone, but they did.

I am a long time AT&T customer, with multiple unlocked AT&T iPhones

Your mileage may vary.

Yes, but they don't have to, and to suggest something like that is both foolish and inappropriate within this forum.

Why is it foolish and inappropriate?

 

I didn't say they would do it for the masses, I didn't say they had to honor the warranty, nor did I suggest anyone try.

 

I only recounted my experience at an Apple store within the past 2 months.

 

Had they not replaced the phone I would have tossed it in the trash and either bought a new one or witched to something else.

 

You need to chill out, you don't know everything there is to know about Apple's practices.

There's a fine line between recounting your experiences and advocating that others do something which not only risks invalidating their warranty but also runs counter to the guidelines of this forum.

Seems to me he was just recounting his specific experience. I didn't see it as advocating something for others.

Can you show me where I advoacted that someone do something that would violate their warranty?

 

I'm at a loss as to how you can read that I suggested someone do what I did..

 

Oh well..

Save it for someone who doesn't see through your transparent attempt to skirt the forum's guidelines.  We can't talk about jailbreaking and unlocking in here, given that this is an AT&T-sponsored forum.  Users who jailbreak their phones run the risk of invalidating their manufacturer warranty.  Stating that you were able to swap your jailbroken and unlocked phone out for a warranty replacement is not helpful or relevant to the discussion at hand, even if it is true.
