    Placing an Existing SIM Card into a new iPhone
    Bottom Line Question First, followed by the Long story. May I use an existing AT&T SIM card in a new iPhone and just set it up through iTunes and perhaps AT&T, or would I need to by a new SIM card?

    I damaged my iPhone. Until I got a replacement, I put my SIM card into an iPhone that we use in my periodontal practice just for texting patients. It worked fine. In fact, I switched it back into the practice phone during the day and didn't have any issues.

    I needed a new phone, but, wanted to wait until the 8 and X came out, to see if the 7 prices would drop, or if I would want an 8. My wife told me to just get an iPhone 6 and once I get the 7, or 8, she would take the 6. She needs a newer model, but does very little with apps. She doesn't do much, besides place calls and she wants some pictures. (I always back up everyone's phone to my computer and iTunes.)

    When I got the 6, I went ahead and set it up with Apple and AT&T, using the SIM card that came with it. I asked the AT&T customer service person if I could have used my old SIM card. She said it wasn't a good idea. I told her that it worked quite well in that temporary phone. She asked me if I had used the cellular internet on the temporary phone, using my SIM card. I don't think I did, but couldn't remember. She said that wouldn't work.

    I have been under the impression that if a SIM card is from the same carrier and fits, then it CAN be used in a phone for the same carrier or an unlocked iPhone. I don't know if the customer service person is a real tech or just customer service.
    If it is difficult to use and set up a new phone with an existing SIM card, how much should a new SIM card cost?

    What is the best course of action?

    Thanks

    As long as the SIM fits and you are using it on the same service/carrier/plan, you can happily move the SIM around to as many phones as you want. The phone with the SIM will obviously have the number and service and it'll work fine. I know people in Europe/Asia have many different phones that they switch the SIM to as they match their outfits or whatever silly..

    Go ahead and use the SIM and it will be fine..the front line customer service are ill equipped to handle anything technical since the scripts they're given seldom delves into any of the specifics..

    Thanks for the answer
    Thank you. That clears things up.

    By the way, I just got back to Texas, from Boston, last night. I had a conference there. It had been many years, since we were there.

    It was a great conference at the convention center and great seeing so many historic sites, again.

    Take care.

    I don't know if it was a unique situation, but the last time we added a new or different SIM card, we had to reboot the iDevice, When they booted, there seemed to be a very short delay and then the "new" SIM card worked.

    Just in case…

    Correct, SIM detection is not done on the fly, rather on power-up. So if you have a device that is powered up already and you insert a SIM into it, it will only work if you reboot it. SD cards are detected on insertion..

    When I purchased my SIM free iPhone 7+ direct from an Apple Store, the sales person took the SIM card out of my older iPhone and placed it in the new one. The new iPhone immediately booted up and locked on to T-Mobile (my carrier). So yes, a SIM card can be moved from one phone to another as long as it's the same carrier.

    There's a lot of controversy about moving a SIM card from your unlocked phone to a locked phone of another carrier. Some say it will work, others say no, the phone will remain locked.

    I'm not 100% certain, but from our own recent experience I think part of the problem and confusion is due to the method used to unlock an iDevice. A "cheap unlocking" method would not work but the compulsory $50.00cdn Canadian unlock fee from the original subscriber did to work with a completely different provider's service.

    And no refund either, now that the iPhone 6 is at the bottom of Todd Inlet BC, maybe entertaining the crabs and fishes. But I'd think its battery would be dead now after almost two weeks.
