any AT&T phone that can take that sort of sim card.
No
iphone and a ipod touch
No because ntelos does not use a sim card in their phones
The iPhone uses the micro SIM card
Verizon does not use sim cards in their phones (except the iPhone). So no you would not be able to use an AT&T Sim card in a new Verizon phone. sorry.
Yes. AT&T is a GSM carrier, meaning all the phones are GSM phones, meaning all the phones require a SIM card to work on a GSM network.
Right now you can get the iPhone through AT&T and T-Mobile. All you do is order a sim card and you can use T-Mobile on your iPhone. WHen it will be able through other carriers some people say will be in January when the iPhone goes to Verizon, and October when it goes to Sprint.
There are many cell phones that has a sim card. Mostly, all cell phones come with a sim card because most of them are prepaid phones. Trac Fone, Verizon and there are many other phones that have a sim card.
That last answer is completely false to get a Verizon Sim card you should look at there global phones for example blackberry storm
First off I'm assuming you meant iPhone 4, not 4G (common mistake). And to answer your question, no. The iPhone 3G has a much larger sim card than the iPhone 4, but you can just take them to At&t and they will transfer everything to the new card for you. If you already have both phones, I doubt they will even charge you.
no it can notwell... TECHNICALLY it can. but only to 3G at&t cell phones. the sim has a unique shape. and one of the MAIn reasons that the iPhone sim card cant be transferred to a non iPhone in some cases... is because the sim card compartment requires a tool to unlock it and take out the sim card. :O it comes with the phone though. but i think you can only transfer the sim from the iPHone 3gSSSSSS cuz it has the actual card in it. the others dont... idk why. :P
The other picture card is the Jack.
