Question about Apple iPhone Smartphone
Hello, All has been fine with my Iphone but..... I just got on a plane earlier today and watched a Heroes episode on the phone... about half way through I realized the phone said "No Sim" in the Service Carrier area (top left).
Now I'm home I have restarted 10+ times, re-seated the sim 5 odd times.........no luck. I put my wifes sim card in and it knew it was the wrong carrier sim, I also took off the Next Sim 2 from my sim and tried that on its own..... Again, it read the sim and knew it was not the right carrier. I put the Next Sim 2 back on tried again but it just went to "no sim installed again"
I live in Australia so its a huge pain to send it back.... can anyone help??
I have a "Next Sim 2" on my Vodafone sim with a JB'ed 1.1.2 otb.
Hold down the power switch at the top and the main selection button at the bottom. After a few seconds a new screen should come up that allows for shutdown should you slide the slider to the right. DO NOT SLIDE THE POWER OFF. Keep holding the two buttons down. Wait until the silver apple logo comes on the screen. At this point you may release the two buttons. Continue to wait while the iPhone reboots. Once the iPhone finishes booting the "No Sim" message should be gone and you should see bars again. No new sim card or reactivation required!

My phone fell and the sim card got loose...check and make sure it is all the way in (at the top center of the phone). I did not have to replace it or anything, I only pushed it in all the way

Ok so i've been having the same problem for about a week and I finally found a fix for it, atleast temporarily. First, turn on airplane mode so it doesn't try to read the SIM card. Then, restart the iphone regularly. Turn the iphone back on and then turn airplane mode back off and if you have service in that location, it should work. I hope this works for everyone else. let me know

I simply popped out the sim card: look at the top of the phone- it's barely visible, but there is a tiny **** with hole in it. You have to get a safety pin or small paperclip to insert into it. It will pop out. I blew the dust out and wiped the card on my shirt. Popped the card back in and voila!

Mine would work for about 10 minutes after a reboot or network power off/on (airplane mode on/off cycle).
It appears that small dents appear on the sim over time reducing the pressure on the contacts. Possibly these could be caused by contact corrosion. But cleaning the contacts didn't fix it. Getting a replacement SIM should fix it long-term.
I put a single layer of cellotape on the back of the sim to make it a tiny bit thicker. Working now.

The easiest way to get this thru is take your sim out and clean it and put it back in and make sure you really press it all the way in, try pushing it more until it recognizes it. It worked for me and i had been trying many things!

I live in the SF Bay area, which has notoriously bad 3G network service, and my iPhone is about 9 months old. I went to sleep listening to music on my iPhone and woke up to the "No SIM installed" message.
I'm in favor of starting with the least invasive solutions first, so I did a few hard reboots. It didn't work.
I read about resetting network connections as a solution and was about to do that next when I read somewhere to try putting the phone into "Airplane Mode" and doing a hard reboot, then taking it off "Airplane Mode". THIS WORKED for me. As soon as I took it off "Airplane Mode" it redetected the network.

Guys, you need to restore or activate your IPHONE. Don't wait for a temporary fix.

This morning my phone said "no sim". I just went to "settings", scrolled down to "general", then scrolled down to "reset". I pressed "reset all settings," and it worked!! I can now use my phone and "no sim" is no longer on the left hand corner.

Try putting a slim piece of paper behind the SIM card. This will press the card firmer against the contact pins. So far, this seem to work for my iphone 3g.

The reason this happens is when you dont get service, the phone goes in no service mode. In order to fix it"
Take out the sim from iphone and put it in another phone and make a call
Then take out the sim again and place it back in the iphone and make a call and it should work.
This is bad because when you dont get service it will happen over and over...for me i carry an extra phone in my car just incase it happens. Thanks.

i'm not sure if this will help but, the first time i tried to use my 1.1.2 otb with a turbosim it didn't work, after trying almost everything, i was told by the seller of the turbosim to setup the turbosim first with the at&t simcard that came with the iphone and then attach my simcard to the turbosim and it worked fine after that with no problems. Maybe try the setup process again with the at&t simcard attached to the next sim 2 and then attach your simcard to the next sim 2 and see if that works.
n.b you wont be able to do the setup with your iphone, it won't let you...you'll have to use another mobile phone preferably an unlocked phone to carry out the setup process.

Okay, for those of you who have been having
issues with the intermittent "No SIM" error, this may be a possible
solution. As many people have, I'm sure, I've dropped my phone a few
times. Every time, the SIM card pops out and then you have to slide it
back in. After being dropped a few times, things inside (such as
electrical contacts) may jar loose or get bent slightly to the point
where no matter how many times you slide the SIM assembly in it will not
Before I share my find, if any of you are experiencing the intermittent "No SIM" error, try pushing on the SIM assembly while it's still inside the phone AND while its not recognizing the SIM. Unlock screen as you normally would, and see if the "No SIM" error goes away. If it starts recognizing the SIM and you notice its working but when you release the pressure the error comes back, read on.
WARNING! (Just in case) I am not verifying this as the "perfect fix". Do it at your OWN RISK, as this may damage the internal components of the phone. I take no responsibility if YOU break YOUR phone.
I had this issue recently and I used a somewhat unorthodox way to fix it.
At the very bottom of the slot in the phone, there is a "sensor" (or contact) that seems to engage the SIM circuits in the phone when the SIM assembly is inserted.
1. Take a small piece of scotch tape (I used scotch tape b/c its very thin) and wrap it around the very end of the SIM assembly. However, don't press the tape against the end of the assembly, instead leave about a 1/32" of the wrap of the tape sticking out, as if to make the SIM holder a bit longer.
*Make sure the tape is sealed nicely or you may have an additional problem, getting the tape stuck in the slot!
2. Reinsert (carefully!) the SIM assembly in the slot. Be sure to push it all the way in, as far as it will go.
3. Check and see if it works! If it does, you're finished. If not, then I suggest taking it to your nearest Wireless carrier for professional advice.
Hope this helps!!

Again, ON and OFF Airplane Mode during Sync.
Again, my pleasure.

Just had this problem as well - got a new SIM card from AT&T and it fixed the problem.
