    I just got my AT&T pre-order 1020 - but there's a SIM card error.
    I currently have a un-locked 920 with a working SIM, the upgrade to the 1020 is on a 2-year contract.

    What's the best way to get the 1020 to work?

    Should I just swap the SIM as described here: http://forums.windowscentral.com/nok...20-1020-a.html
    Since I only have one active line, do I need to call AT&T for a IEMI# update?

    Or should I call or go to an AT&T store so they can fix the 1020 SIM?

    Did a new sim come with the device? If it didn't and you are getting this error, I would call customer service, and if they are no help, go to your nearest At&t store.

    Helped my mom with her pre-order upgrade 1020. I went here to activate the phone and new sim card:

    Is this what you needed?

    I just removed the sim from my other device and popped it in the 1020. Any reason not to use the previous sim? Came in my case with the HTC One.

    Yes, I have a new sim with the 1020 and https://www.wireless.att.com/activations/ worked - thanks!

    Note: I did have to use the pin/SIM extractor in the box to pop out the SIM and reverse it - it was backwards with the little hole on the left, not completely in.

    would that link work for buying the phone outside of contract and putting my old sim card in the new phone? I had a iPhone 5 so I have in one of those sim card adapter. I got the Sim Card error a couple times but it would go back to showing AT&T again. I was just wondering if this is an issue with the phone or sim card.
