If this is for an account that is not for a company:
Walk into a corporate owned retail store and say that you have damaged your SIM. Say that you called in and they told you that the store would give you one for free. Take the SIM home and insert it into the iPhone BEFORE activating the phone through iTunes.
You still are liable to a new 2 yr contract upon activation of the iPhone onto your account.
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 but you will have to buy a new sim card and also some minutes to add to you new sim card. You can find the sim card and minutes card at a 7eleven in Thailand. I did in Phuket and it worked. The phone will be used as a prepaid phone only though that's the only way I know how to use it.
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.
CAN YOU PLEASE HELP ME OUT HERE..
It would probably be cheaper to purchase a new sim card online but it would be easier to make it compatible with your phone if you buy it at the phone company's store. Sim cards are directly link to your phone account so a new sim card would have to be relinked to your account in order for you to use it.
NO 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 new 1 ...
An AT&T 3G sim card will work in a new iPhone.yessss you can :) but the box for the iPhone comes with a little tool to help you open the little compartment for the sim card.... its hidden right under that part where the phone is displayed, under that flap thing....... yeah... WELL its silver and has a small tip! not hard to miss! :) okay bye!
Yes, you can use the phone simply by getting a new SIM card.
You have to buy a new phone or buy a used one.
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.
Put the SIM card from the new phone into the old one. Copy the contacts from the old phone's memory to the SIM card. Put the SIM car back in the new phone - then - either copy the contacts to the new phone's memory - or leave them on the SIM card. Either way - the new phone will find them.
Look at the top edge of the iphone 3g. there is a long button, and a headphone hole. See the tiny hole between the two? stick a small object, such as the little pick that comes with it, in the hole, and the sim card holder will pop out.
