Can I use iphone 3g in iphone 4 or 5

I no longer have a contract but still have AT&T as my carrier. Is it possible to use my sim card in iphone 4 or 5 ?

Actually, the 3G, 3GS, and original iPhone, along with most other GSM phones from that era, use a Mini SIM.
A "full sized SIM" card is (was actually, since nothing uses them any more) the size of a credit card! Gaak!
If your phone doesn't look like this, you probably don't have a full sized SIM:

(just an interesting piece of trivia thrown out there for the sake of picking nits )

  • How can I use Iphone 4 as an mp3 player without a sim card until I get one?

    Hi,
    How can I use Iphone 4 as an mp3 player without a sim card until I get one? I just bought the phone and each time I try to switch it on to use the mp3 player, I cannot. It asks me to insert a sim card and I don't have a sim card yet. I was thinking I could use the mp3 player function of my phone until I buy a sim card.
    Thank you for your help in advance,

    Thank you, I understand, yeah, I knew that, my phone is factory unlocked and I am going home, which is obviously not in the States and I am thinking of buying a local carrier there. However, I still have 2 weeks before I leave and cannnot wait to start using my Iphone 4. I thought at least I could use the mp3 player function. So as far as I understand, I cannot activate it without a sim card. I have been using metropcs for about two years and it does not have a sim card. In this case, do I really not have another choice but wait for two weeks to listen to music? My Mp3 player just failed me and I really need to listen to music but on the other hand, while I can use my iphone as an mp3 player in two weeks, I don't want to spend more money on a new one. So, do you have another suggestion? For instance, can I use a friend's sim card to activate mine? Would this cause any trouble, when I go home and buy a local carrier? I think these questions might kinda sound weird to you, but first time with an Iphone, extremely excited to start using under my circumstances, I need help   thanks,

  • Can you use Iphone hotspot to wirelessly connect to apple TV

    Can you use Iphone hotspot to wirelessly connect to apple TV.  ie I have no router but am interested in playing music from phone to apple TV.

    Yes in theory, though do check your phone contract small print and keep an eye on your data usage - in theory local data sent across the LAN created by the hotspot should not use 3G data but some carriers seem to treat it as internet data usage.

  • Can i use iphone in the philippines?

    waiting so long for the iphone to be released now that it is, im having doubt buying it. does exclusive to at&t means that the iphone cant be used using other network provider? cause i cant use at&t even if i want to, cause i live here in the philppines and we dont have at&t here. ^^ someone please tell me if i can/ i can't use iphone here in RP. Thanks!

    cingular and at&t are the same company.
    in short here's what you need to use it in the phillippines: a cingular/at&t wireless account and international roaming turned on. oh and about $3/min i believe (not including data costs).

  • Can i use iphone to iphone for free international call and text?

    Can i use iphone to iphone for free international calls and text messages?

    If both iPhone users are on iMessage, texting will be free, though there may be data charges if you do not have Wi-Fi. You can use FaceTime Audio in iOS 7 and later to call people but regular phone calls still count against your phone plan.
