1. Take the pin (which should be in the box that came with iPhone 4 or if not use a needle etc.)
2. Then, there should be a little hole on the rightside of the phone.
3. You push the pin hard in to the hole.
4. It should pop open and now insert the sim.
The iphone 4 comes with a micro sim. Your normal sim will not work with it. My AT&T dealer says he can transfer data directly from your sim/old phone to your new iphone 4.
You can fit a SIM card from your HTC Wildfire to an iPhone 4 by using the SIM port included in the iPhone.
No!
You have to put a small tacking chip in the sim card and download an app on your 4s to track it
Yes it can be swapped. I actually swapped my razr's sim card to my iphone. Nothing happened. It works perfectly.
No
If your 3GS is locked, you can't insert a SIM card.
Yes, as long as your with the same service provider. It also has free Wi-fi. Unlike the "Blackberry" you can just put in your old Sim card and it should work just as well.
Yes , i phone 4 want micro sim ,Because there are now several countries where the iPhone 4 is sold unlocked, everyone can choose the best network and tariff for their needs while not tying themselves down to a long contract. There is no doubt that this is the way phones should be sold, however, buying the iPhone 4 in this way has a distinct problem all of its own: the micro-SIM card.
any AT&T phone that can take that sort of sim card.
Yes the iphone 4 uses whats called a micro sim card it is smaller then the regular sim card out there. At www. phonetraderonline.com they can custom cut your existing sim card or provide you with a micro sim for your carrier.
Yes, Yes you can.
