Last night my iPhone's sim card stopped working, and today it continues to say "no sim". I'm not in arrears with my payments, and I have tried over and over again to restart the phone, to no avail.

Any suggestions??

Really fed up with Vodafone!!! Had similar problems when I first got my iPhone - first it didn't connect, then the sim card didn't work, then they kept trying to connect it and it didn't work. I've had it for nearly 4 months now and this is the first time since I got the sim card to work that it's failed on me.

Hi Madeleine -  yep, most likely it's an Apple iPhone fault. Poor old Vodafone is blameless (this time). Here's Apple's fixitup procedure from their website.  It's really easy - just a backup & restore.

iPhone 4S displays 'No Service' or 'No SIM Card Installed'
http://support.apple.com/kb/TS4148

Symptoms
In certain situations, iPhone 4S may have difficulty recognizing a micro-SIM card, resulting in the following behaviors:

• "Invalid SIM" or "No SIM Card installed" alert appears intermittently.
• Status bar displays "No Service" or "Searching" in a location with good network coverage.

Resolution
If you encounter any of the above symptoms on your iPhone 4S, follow the steps below.

• Back up your user content and settings using iTunes or iCloud. See this article for more information.
• Restore your iPhone 4S using iTunes.

PS  There can be other reasons for the 'no sim' message you're getting, again it's Apple-related.

iPhone 4S 'No SIM card installed' is not a new problem
Annoying, but this isn’t an iPhone 4S specific issue - it also affected the iPhone 4, and apparently it’s down to a design flaw (or perhaps manufacturing imperfections) with the SIM card tray eject mechanism causing a short circuit with the SIM card contacts. And the solution?  Sticky tape!!

Hi madeleinedeleo,

Peter has posted some great suggestions to help resolve the issue you're having with your service - thanks Peter! I'm not too sure about the sticky tape though - we may need to call MacGyver! I'm glad the SIMs been working for you for the past four months, and I can help get it back online for you now.

If Peter's suggestions don't help, try logging into your MyVodafone account - if you're able to log in, we'll know your number hasn't been disconnected - only active numbers can be accessed in MyVodafone. If your number's active, but still showing "No SIM" after a factory restore, try the SIM in another phone.

I know this can be tricky, as the iPhone 4S has a microSIM - if you don't have access to another phone that will accept a microSIM, just pop into your local Vodafone Store - we'll be able to test the SIM card for you.

If it doesn't work in another phone either, I'd like to take a closer look at your account, to determine the reason the SIM is not working - I'll provide you with my email contact details at that point, so we can move our conversation private.

Thanks,

Kirsty.
