My iphone 4, sim failure and no service

I just replaced new Iphone 4 last week in Apple store, Chadstone and after 3 days, it says sim failure and no service suddenly. I tried many times, switched off and on but still says no service. Do you have any ideas and solution please.

Hello, I have been having the same problem which seems to have occurred out of the blue. I pay my phone bill on time and as far as I know I haven't used up all available space. Sprint service can be problematic but this time the Sprinters were not responsible. To be honest I can't tell you why this occurs. I can tell you how to fix it :) just reset your phone (first reset the settings and if that doesn't work, restore the phone to factory settings). If this does not clear your problem you should talk to your service provider. I just reset my phone's settings but 30 minutes ago, and BAM all's well again. :) lets hope it lasts ;) good luck.

IPhone 4s and Sim failure and No service issue

Ok,
Few days back I asekd questions regarding few other issues with iPhone 4s. here is it, https://discussions.apple.com/message/17068754#17068754
Few gentlemen told me, to replace sim card. Here is what I did,
1) I am from India. I was using Vodafone 3g micro sim. Everyday, 4-5 times in the ideal mode I got messages like Sim failure and invalid sim. I have to restart my iPhone everytime. Then only it was working.
2) I posted the question, people said its my card problem
3) I bought new BSNL 3G micro sim card for iPhone. I inserted the card and got 3G working.
4) After 3 hours, I saw No service message. I waited for some time, i went to outside to see if it was a network issue. Nothing changed.
5) I rebooted my iPhone, it immediaetly picked the network.
6) After few hours, again it lost and said no service.
7) I then didn't rebooted it.
8) In the morning, I saw Sim Failure and invalid sim message. Useless
9) I now rebooted and Sim is working with 3G network.
Now please ,
is this iPhone issue? It is for sure. I am tired now. Battery is dying and with this Sim Failure and No service, I am totally disappointed.

Hi Ahelpyguy...
I read all your messages above , I am facing the same problem as u faced.
My Iphone 4S and it was working fine (5.0) until i upgrade to 5.0.1(9A406).
Now I am facing alot of network issues. I get messages liek NO Sim , SIM FAILURE.
I even restored the sowftware from ITUNES but i am still facing the same problem.
I was using Vodafone first but I heard that due to problem in micro sim reader of Iphone 4s i shd use a 128 K or 64 K sim.. Since only Airtel provided 64K sim ...I installed that in my phone. But still i am facing the same issue.
I would appreciate if you can tell me whats Tweaked version of 5.0.1.
the current software installed on my phone is 5.0.1 (9A406).
Thanks
Prateek

Before getting all pouty, why don't you bring your phone into Apple for evaluation. If found to be defective, it will be exchanged.

SIM Failure and No Service

Just trying to see if there's a fix for this.
Several months ago I was having this problem, it went away and now it seems to have surfaced again. It started this past Saturday and I'm not sure why or, what to do about fixing it. My phone will sporadically display the message 'SIM Failure' and then where the Verizon logo and signal bars are, 'No Service' is displayed. If I power down and restart the phone, it does 'Searching' a bit before finally showing he bars and VZN logo. Sometimes it will maintain that for an hour or so before another SIM Failure message, sometimes, I immediately get the message and have to restart my phone over again.
I didn't think these VZN iPhones had SIM cards, I thought we were CDMA or something like that. I've had the phone since February so I don't know if this is a device issue or a software issue and I'm trying to figure out if I should try to return it before my 1 year warranty thing is gone.
I'm on 6.0.1 (10A523) version of iOS so I believe I'm current as far as updates to the phone go.
Any help/information/guidance would be greatly appreciated.

It sounds like both of you have tried some great steps to research what's going on with the SIM errors on your iPhone 4s devices. The Version 6.0.1 (10A523) is the most recent software from Apple. And although you don't use the SIM on the Verizon Wireless CDMA technology here in the United States, the iPhone 4s come with the awesome capability to use a SIM card for global GSM services too. Which is why you're seeing messages about a SIM. You can check out http://bit.ly/zXnl81 to see where the SIM is on your phone and how to remove/reinsert it to try to refresh it's connection to the phone.
There's also a wonderful support article from Apple at http://support.apple.com/kb/ts4148 to help with every step you may need to take to resolve random SIM errors on the 4s. Many times just removing and reinserting the SIM will do the trick, but Apple also includes steps on how to restore your phone to ensure the error messages stop.

HT1430 what happens when i always get sim failure and loosing service and get sim Failure

im always getting sim failure on my phone and always loose service

First step would be to go to your wireless carrier and get a new sim.
If that does not work, post back with the exact wording of any error
messages you get when new sim is in the iPhone. Also post what
it says when you look at Settings=>General=>Carrier.

My iPhone 5 keeps saying sim failure and invalid sim I need help please!?!?!

My iPhone just said "SIM failure" and now says Invalid SIM in the upper corner. What's this all about?

My iPhone just said "SIM failure" and now says Invalid SIM in the upper corner. What's this all about? Any ideas on how to resolve this.

Looks like the Sim card had a catastrophic failure. Burnout, short somethng like that.
You can try to take out the tray and reseat the sim card inside and see if that gets it back.
Also try resetting the phone at least once by holding down the home and power buttons until the Apple Logo shows up.
If none of this works you'll have to contact your cell carrier to get a new sim card, as it probably fried and is no longer functional.

Have tried to restore settings due to problems, now Iphone shows Sim Failure, how can I get back to using my phone? Please help, its a business phone. :(

Hi, I have tried to restore settings on my Iphone due to problems I was having with the phone cutting out when talking on the phone, now Iphone shows Sim Failure, how can I get back to using my phone? Please help, its a business phone.

Hi jclarke64,
Thank you for contributing to the Apple Support Communities.
I'm sorry to hear that your iPhone 4s was lost, and glad that you were able to upgrade.
If your iPhone 4s was backed up to iCloud or using iTunes, you can restore the backed up data to your new phone.
See the steps in this article for help with restoring from a backup:

SIM Failure contact your service provider?

I have a newly purchased Dell E6420 with the DW5800 4G (LTE-3G) Mobilebroadband card embedded. I downloaded and installed the VZ Access Manager Version 7.6.6.5 which applies to the installed card.
While activating I am getting a SIM Failure contact your service provider. Help....

Hello A1AJake! I can help get your embedded card activated. It's best to start by reviewing your account. I'll need you to send me a personal message through the VZW forum. I'll need your full name and mobile number in order to assist. Thanks!

IPhone 'SIM failure' and 'invalid SIM'

My iPhone 4 with Bell mobility was working just fine. I put it down and when I came back an alert saying 'SIM failure' appears and then instead if my carrier in the corner, it says 'invalid SIM'. Should I take my phone to Bell to get my SIM replaced or go to apple? And is this a hardware problem?

Try removing and re-inserting the SIM. If that doesn't fix it, get a replacement SIM from Bell.

Iphone 3GS sim failure

I bought an iphone off ebay who said the phone was locked to orange, i put my sim card in (orange) and it keeps saying sim failure what does this mean? i've done everything to try to get it to accept it but it wont have it

Does you SIM work in another phone? If it does chances are your phone was hacked/jailbroken. Most phones sold on ebay are or were at one time or another.

Iphone 5 sim card and europe

I have an iphone with AT&T and travelling to France. I wanted to buy a sim card there to use for calls and data but wondering if the phone needs to be unlocked for this..
any ideas or suggestions?
thx

Hey Skyao,
Yes, you need to unlock the phone to use a non-AT&T SIM card (wether this is domestically or overseas, such as Europe).
If you contact AT & T, they should be able to unlock the iPhone 5 for you. Please note that you may be charged an Unlocking fee for them to complete this process.
I hope this is helpful .

Iphone 5 - SIM card and contacts

Are new contacts stored on the SIM card and how do you see what is on the SIM card? Also, why does an old contact name and number (one that is no longer in my contacts app) appear when i start to enter the name of the person i am sending the text to? And lastly, in the same "new message" app when i am trying to compose a new text message and i click on the + symbol to add a new contact, my contacts are displayed in order by last name instead of first name (i have already gone to settings, contacts, sort order and display order and set it to first, last?

Iphone stores NOTHING on the SIM card.

TS4148 Hello I have a new iphone5 and I did the new update last night and now i'm getting SIM Failure and my pnone won't work unless I turn it off and on again. I never had this probelm before. Please advise.

My phone is saying SIM Failure after I did update last night.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)
