Suddenly my iPhone 3GS started showing Invalid Sim.

It was working fine, I turned off my phone and restarted and it is showing as Invalid Sim. The sim is working fine in another phone. Can any one give some solution for this.

I also had 'invalid sim' when i upgraded to IOS7. My phone is almost two years old and worked fine with the sim until now. I upgraded the IOS in my ipad mini first and that worked fine. I rang my provider Orange/EE and after trying various resets and restores they said they will send me a new sim to see if that works. I'm about to go on a short trip so this problem is a real pain as can't make or receive calls or texts using it. I suggest you ask for a new sim too, but i am yet to see if that fixes it.

    You could try removing the sim card and cleaning it - then put it back.
    I assume that there is supposed to be a sim card in your model of iPhone 5 ?

    I have got an iPhone MC605J version 6.0 soft bank iphon 4 but unable to use it in India.  I am trying to use Airtel sim but the phone is showing invalid sim.  So please help me out to unlock it.

    No one here can help you, & Apple can't/won't help you. Fact is, there is no way to get that iPhone officially unlocked. Only Softbank can authorize the official unlocking of your phone, but they won't. Softbank does not offer official unlocking for any iPhone.
    It is what it is.

    trying to active my old iPhone 3gs. it showing that activation server is temporary unavailable and on the iTunes showing that there is no sim card installed in the iPhone you are attempting to activate. I unlocked my phone then i upgrade it, after that this happen. i tried with other sim same message come again and again.if any body know solution let me know. thanks

    Was the SIM card activated on another phone? I assume this is an ATT style trying to use on T-Mobile? Was the SIM installed correctly? Is the carrier (like T-Mobile) operating IOS 6 devices yet?
    If the SIM is a valid SIM from say T-Mobile, you may want to contact them for assistance activating the SIM card.
    Activation and SIM issues typically point to the carrier. And if this was a CDMA phone say working with verizon, it will NOT work for ATT or T-Mobile as they use different electronics on the 3GS. The SIM slot is for international use only.

  • Please i purchased my iphone from a friend and i updated the ios and now its showing invalid sim

    please i purchased my iphone from a friend and i updated the ios and now its showing invalid sim. please i need help because i have to use my phone at the office tomorrow.

    ASk your friend who unlock the phone for him/her.
    ONly the carrier that the phone is locked to is authorized to unlock it.
    bAse on your description, it sounds like your friend had his/her phone hacked to unlock it from the original carrier.

  • HT201328 My unlocked iPhone 4 shows "No Service" and after airplane mode turned on and off, shows "Invalid SIM"

    I recently bought two iPhone 4 phones from my colleague in USA. He unlocked these phones from AT&T. But I did not test it. However, now that I am back to India, and inserted my Indian Vodafone SIM car, the phone shows "No Service" and if turn AirPlane mode ON and then OFF, a message comes as "SIM Failure", and the top left corner shows, "Invalid SIM".
    Now, how do I confirm whether my colleague was successfully able to unlock these phones ?
    What are the steps to make my Indian Vodafone SIM work ?
    Any support appreciated.

    Hello there Vicky,
    Here is a great article for troubleshooting the Cellular connection on your phone. From article iPhone: Troubleshooting a cellular data connection found here http://support.apple.com/kb/ts3780:
    Follow the instructions below for assistance with troubleshooting cellular data issues on your iPhone. After performing each step, please test to see if the issue is resolved.
    Toggle airplane mode: Tap Settings, turn airplane mode on, wait three seconds, and then turn off again.
    Restart your iPhone.
    Ensure that your software is up to date:
    Check for a Carrier Settings Update. Tap Settings > General > About.
    Check for an iOS Software Update. Tap Settings > General > Software Update.
    Note: Some updates may require a Wi-Fi connection.
    Remove the SIM Card and reinsert it. Allow the iPhone to acquire the network again.
    If your SIM card has SIM PIN enabled, try toggling it off: Tap Settings > Phone > SIM PIN.
    Try another location. If a different location works, but the original location still does not, contact your carrier to report the issue.
    Reset network settings: Tap Settings > General > Reset > Reset Network Settings.
    Restore the iPhone as new.
    Contact your carrier to:
    Verify that the iPhone is properly set up on the account with the appropriate, current data plan.
    Verify that there are no account-related blocks.
    Find out if there are specific error messages in the carrier logs that could help determine why the issue is occurring.
    In order to verify if the phones have been unlocked, the original carrier for them would have to be called.
    Take care,
    Sterling

  • After updating the iphone 4s's software it has starting showing 'no sim'.

    After updating the latest software IOS 5.1 for iphone 4s, it has started showing 'no sim'. Not getting any service now? Please help!!

    To be honest not being able to send or recieve messages and data is a carrier issue, not a phone issue since u said that your calls are working, if i were you my first course of action would be to get a new sim card from virgin mobile, or to restore the device as new one more time, if you restore the device as new AND get a new sim card from your carrier and those features still dont work, i would take the device to an apple store

  • IPhone 3GS is showing no service

    My iPhone 3GS is showing no service, I have reset the network settings but that didn't seem to work. I then restored the phone iteself but it still shows no service.
    The phone is on O2 and I have tried a few other sims, but it still doesnt seem to work. The iOS is 6.1.3, I have been told this may be the problem but it was working a couple of days ago.
    I was also told to try these steps which didn't seem to work:
    1. Disable 3G in Settings/General/Network
    2. Power off the iPhone by holding the top lock button down then sliding to power off, leave the phone off for 30 seconds
    3. Power on the iPhone
    4. Reset network settings in Settings/General/Reset
    5. Turn on 3G
    6. You should be able to find the network now
    I don't know what elese I can do, I would really appreciate anyones help, thanks.

    Basic troubleshooting steps
    Reset the iPhone by Holding both Power and Home Buttons together till Apple logo appears.
    Restore to a backup.
    Backup, Restore in iTunes setup as new.

    I have no idea why this has happend ive been using the phone for 2years bought it on pay as you go and now all of a sudden its stating the above error i have never come across this problem before and currently im using 3GS and Iphone 4S

    Sounds like it's been blacklisted.
    Even if it hasn't, downgrading voids any warranty and forfeits all rights to support. You hacked your phone. You can't get help here.
