I see a lot of you posting incorrect information and wanted to clear the air. A 3G sim will not work in an lte phone. There is most definitely a difference. But an lte sim will work in a 3G phone. That's why some of you are able to swap between certain devices and others cannot. I run into this issue with customers getting loaner phones almost everyday.

I was always curious about this one. Because they used my 4S sim card in my galaxy 3 when I upgraded.
Best buy mobile, but we sell att phones (obviously :P)Quote:

So this explains why I can put my Samsung Galaxy S3 SIM card into my iPhone 4s without having to call AT&T.
Thanks for clarifying...
Sorry to say, but there is absolutely no difference between 3G sim card and LTE sim card. In my Samsung Galaxy S3, I'm using my old iPhone 4 sim card and it still works fine. All you have to do is switch the data plan from iPhone to LTE. It's the data plan that matters, not the sim card. I went into AT&T and ask about if I needed a new "LTE" sim card and they told me that only the data plan needs to be changed in order to have functioning data for your new LTE phone.
Data plan is incompatible.Quote:

From my understanding you need the newest sim card that does not have the 3G logo on it to get LTE. The new ones just have the at&t logo on them. It also needs to be on your plan as lte whatever as well. The newer ones will work for all phones 3G 4G hspda and 4G LTE.

All I know is I have an old SIM from when the iPhone 4 was released and on my account I have the LTE data package.
Without calling AT&T I can place my SIM from my Samsung Galaxy S3 into my iPhone 4s and the data works, period. I do this a few times a week, thus no call to AT&T is needed.
Now if I could do the same with BlackBerry 10 upon release, I'd be happy...
Just because your 4S wasn't LTE doesn't mean the SIM wasn't... All new AT&T SIMs were LTE compatible before the network launched.
