  • HT4528 Why does my phone say invalid SIM?

    My phone says invaild SIM. I cannot text, call, or connect to the internet!!! What is the problem??

    Yes, All iPhone 5's have SIM cards... regardless of carrier.
    Remove and reinstall the SIM.
    If the issue continues, get a replacement SIM from Verizon.
    FYI, Verizion uses SIM's in all there LTE devices.

  • Why does my phone say invalid sim and why can I not phone or send messages on it

    I cannot use phone or text today. What is problem?

    Usually cuz its locked to a network other then the SIM's. Did you swap SIMs today? Or it's not seated properly. Take it out and reinsert carefully.

  • Why does my phone say no sim card?  How do i fix?

    I dropped my phone and now it says No Sim in the upper left.  I cannot use the phone.  how do i fix?    

    This happened to me recently. I had to turn the phone on and off twice. I also had to press on the top of the frame of the phone where the sim card is. My issue actually happened when the phone had not been dropped. Good luck.

  • TS3274 Why does my iPad say " No SIM " in the upper left corner

    Why does my iPad say " No SIM " in the upper left corner ?

    Hi Edwardtracey,
    Welcome to the Support Communities!
    It sounds like you have a cellular data plan and there is no service where you currently are.
    The article below will explain this feature and how to turn the setting on/off.
    The article has more details and screenshots, but I've quoted highlights below for you:
    iOS: About the Cellular Data setting
    Cellular data is used for data communication in cellular networks. It does not affect your ability to make or receive phone calls or to use Wi-Fi networks for Internet connectivity. If you turn off cellular data, you will be unable to:
    See the cellular data icons in the status bar (for example, LTE or 3G).
    Send or receive MMS messages. However, you can still send and receive SMS and iMessages if you're connected to a Wi-Fi network.
    Retrieve or listen to new Visual Voicemail messages. To retrieve these messages, enable Cellular Data.
    Use Personal Hotspot.
    You can adjust this setting by going to:
    iPad: Settings > Cellular
    Additional Information
    You can also enable or disable cellular data for certain iOS features from this setting:
    I hope this information helps ....
    Have a great day!

    Mine is doing the same. I've tried several different cards all with the same response.

  • Why does my ipad2 say no sim?

    I bought my iPad online and have been using it for about a month with both wifi and 3G. Why am I suddenly getting a msg in the upper left corner that says no sim?

    There may be a problem with the SIM card, or the SIM card is not seated properly.
    Have you tried removing and re-inserting the SIM card - with the iPad powered off when doing so?

  • Why does the iphone say no sim in activation screen when i have inserted the the iphone original sim

    i have bought a atnt locked phone, i try to activate it but it says no sim.when i insert the atnt original sim, nothing happens and it still says no sim. What is the problem with it? can a activation sim be used twice?

    What is the problem with your sim tray? If you tried to get your sim out using something and accidentally scratched the sim chip, your sim chip is broken and it is not free to fix. On the other hand if other sims work, you can call AT&T and ask for assistance from them.

  • Why is my ipad saying 'Invalid Sim'?

    I've had my iPad 3 since March 17th - two months - and have enjoyed having 4G LTE cellular service.  I've paired my iPad with a black Kensington bluetooth keyboard, but since the past weekend, two major problems have arisen. 
    First, I can no longer access cellular service - I get an "Invalid Sim" readout on the top left line of my iPad, rather than the customary 4G LTE that should appear, and normally did.  So, something's wrong there.
    Second, right about that same time, my Kensington bluetooth keyboard has gotten glitchy big-time. When I attempt to type a note in Gmail or even the Notes app, whatever letter I hit continues to repeat endlessly.  If I hit the backspace key, the cursor will continue endlessly, deleting all my previousing typing.  Even more oddly, whether or not I turn off the keyboard - and I've tried this both ways - the iPad's onscreen typing is no longer popping up!  This iPad needs some serious help.  Apple...?

    Rudydale-
    The on-screen keyboard may not appear when your iPad is paired with an external keyboard.
    Can you remove the SIM?  Just removing and re-inserting it may clean up its electrical contacts and make it work.
    One other thing you can try is a reset (reboot).  Hold both the Home and Sleep buttons for several seconds until the Apple logo appears.  Ignore the "Slide to power off" arrow.  The iPad will restart after a couple of minutes.  Resetting this way will not hurt anything, and sometimes clears up mysterious problems.

  • Why does my phone say can not connect to itunes store

    how come when i try to get an app or anything else for that matter my phone says that it can not connect to the itunes store.

    Go to settings and ensure a wi-fi connection. If you are connected go to settings>general>date&time>turn automatic time off and ajust the time to one year ahead. Go back to the app store and check connection. If it works, GREAT go back to settings, general and turn auto time back on in date&time.:)

  • Why does my iPad says no sim instead of saying iPad on the top left?

    I don't have a sim card but Usually the iPads without the sim card say iPad on the top left corner but mine says no sim. Please help me out.

    Try taking the SIM out, blow in the hole, and then put it back in.

  • Why would my phone say no SIM card?

  • Why does my phone say it has no service?

    I am getting voice mails but no calls...and I can't listen to them due too no service. Bill is paid!

        No service is no good, Happygolucky23. Let's find out what's going on. What is your zip code? Did this start after installing a new application or update to your phone? If you haven't already, try powering down your phone and removing the SIM card for about 30 seconds before powering back on to refresh the phone's service connection.
