Hey
It depends on your location and your network For example, in the US, AT&T have a deal with Apple for a 2 year contract.
Now, you can always jailbreak your iPhone and then put in the other Sim card. You will retain your number. But I can't really say if your network will trace it or not.
no
Stick a paperclip into the little hole on the top, and the SIM card should pop out.
It depends if the original phone the SIM card belonged to was saving them to the SIM card itself. Here's some clarification: The SIM card will retain contacts from a previous phone. The iPhone will not recognize SIM contacts until they are imported to the Contact list via Settings > Mail, Contacts, Calendars > Import SIM Contacts The iPhone does not save contacts to the SIM card, and therefore if the SIM is from an old iPhone there won't be any SIM contacts present.
No
Then just get an iPod touch ..
In some situations, the status bar on your iPhone might display No SIM, even though your iPhone has a SIM card.
iphone
any AT&T phone that can take that sort of sim card.
Go to iphone store and check your phone out simple..
I dont know why but i think you can just buy an iphone off amazon.com or overstock.com and put in your own phone company sim card into it. (EX: like I could put my T-Mobile SIM card into the iPhone.) Yeah that would not be a good idea to put a different phone company sim card into another phone company phone. that person is DREAMIN!
No, the sim card is located in the top of the phone only.
A SIM card is a small card with a chip on it that contains data pertaining to your network provider and your personal cell phone number. No phone will work adequately without a SIM card; you will only be able to make emergency calls from a phone, even an iPhone 3GS. You will still have to insert your SIM card into your iPhone after a factory shutdown to be able to use the phone to make/receive calls, texts etc.
You have to buy the card from a newsagent and call the number
