    My iPhone has been working fine but since last night I've not been able to use the phone or Edge. When I try to use the phone it says "No SIM card installed". On the upper left of the screen it says "No SIM." I turned the iPhone off and back on to no avail. I also removed and inserted the SIM card.
    Anyone have any suggestions?

    You know the exact same thing happened to me yesterday... I had my phone about a week and no issues, then all of the sudden I wake up and it said "No Sim". I took it in and out a few times with no luck, then I went to the AT&T store and got a new SIM - went through the activation agian (which only took like 2 mins) and it was fixed. Maybe the heat from the phone damages the sim card or something. You should get a new sim and it should be fine.

    My phone did seem especially hot last night. I attributed it to my leaving Wi-Fi on for hours even though I wasn't literally using it (some of this time it was in my pocket or I was charging it). In general, should the iPhone not be stored in your pocket?

    I'll call my AT&T store when they open to see if they have the iPhone SIM card.

    It is the same sim card they put in all of their phones. They will have one.

    I always leave my phone in my pocket and in the rubber InCase, Ill see if it happens agian. They will have a sim just go there, the iPhone uses a regular AT&T sim card which they have a ton of.

    I doubt it is because of the heat.

    It is not uncommon for cell phones of all makes and models to get the "Insert SIM" Message. I got it on my blackberry, slvr, razr, and multiple cheap flip phones.

    Take your phone by the AT&T store and tell them it says "Insert SIM" and they will replace it with a new one. You'll be in and out in a few minutes.

    As a follow-up, I got a new SIM card, reactivated my iPhone through iTunes, and everything is working fine. Thanks for those that helped earlier today when I was very concerned.
    The AT&T manager said that mine was the first iPhone to have a SIM problem she knew of, so hopefully it was a very isolated incident.

    Yes, activation was very quick (< 60 seconds I think).

    I had to replace my sim to get it activated on the 30th. Evidently there were a few that had problems on the initial batch.

    Same Problem - "No SIM card installed."

    I bought my iPhone yesterday and when I plugged it in to my comp the error message "No SIM card installed." appeared. So I went back to AT&T and got a new SIM card. Same error message. I am now on my third SIM card and am getting fed up. Does anyone have any advice?

    Hard reset may solve the problem

    I had the same problem. Reading this area I took my iPhone back to the AT&T store. The tech there did the following to reset the device.

    He held down the power switch at the top and the main selection button at the bottom. After a few seconds a new screen came up that said slide to the right to power off. He didn't do that instead he just waited until the silver apple logo came on the screen. Once the phone finished booting the "No Sim" message was gone and I had bars again. No new sim card or reactivation required.

    i just was confronted with the same problem. i figured out that if you goto settings and then goto general, then reset at the bottom of the list, and then reset your network settings you can solve to no sim installed problem in like 30 seconds or less. i dont know if there was a problem with your physical sim card but by just resetting the network settings it solved the problem for me.

    I tried the power reset AND the network settings reset to no avail. Mine still says "no sim card" ...

    I'm curious if the problems are occurring after or because of one of these:

    - Battery drained to power off
    - Synced with wrong account on iTunes
    - Synced before first upgrade (software or firmware)
    - Sync failure due to passcode

    If those who have a similar problem can reply back, I'd appreciate it. I'll be heading over to the AT&T store tomorrow for a new sim card...

    Just to note, my battery was drained, I synced for the first time before setting up my iAccount, the initial sync failed without unlocking the iPhone with my passcode first, and it was using the initial software/firmware, which are now updated - second day failure, still "No sim card installed"

    Got it

    I was having almost the exact same problem. I tried everything suggested on this page (except go to an AT&T store) and nothing worked. What I did was I turned off my iPhone completely (holding down the sleep and menu buttons for a few seconds and sliding it off) and took out my SIM card. Upon studying my SIM card, I realized that there was a smudge on it, so i VERY gently cleaned the card. Then, before putting the SIM card back in, I turned my iPhone back on, waited about a minuet and put the SIM card back in. It took about 5 seconds and then I got the bars again. So maby these SIM cards problems are just smudges that keep htem from comunicating w/ the iPhone.

    Just to update my own situation: I went to the AT&T store and got a new sim card. All is well with the new card, and I'm now on my second software upgrade from Apple (2.0.2) with no problems.

    The tech at the AT&T store said that there are bad sim cards sometimes, and the problem can happen at any time in any phone.

    I don't doubt that dirt could cause connection problems, but I wouldn't hang my hat on that being the only cause. More than likely, we're all dealing with a similar issue that has different causes. Bottom line... when in doubt, suspect the card.

    I do not think it's isolated. I have had my phone since Saturday evening, it is now Tuesday evening and it just happened to me. A tad irritating since I just got this phone and was worrying about the thing dying on me (ie: battery, cracking screen, etc), i didn't expect it to be the SIM and now I see it happens to many others.
