IPhone :: "Invalid SIM" Message On 4S Running IOS 5.1.1?
May 26, 2012
I've had my iPhone 4S since launch last year. All was going well until last week. I got an invalid SIM message, so I switched the phone off and on again. That seemed to work for about 3 days, but since a few days ago, I get the "Invalid SIM" and also now "No SIM Installed" message more often than not making the phone virtually unusable. I've tried using a new SIM. No difference. I've tried doing a restore from iTunes. Also made no difference. I am running the latest software. I can't seem to be able to go back to iOS 5.0.1
Info:
iPhone 4S, iOS 5.1.1

I use my BB for personal use only. The email account I have registered on the phone is my gmail account. Just today, I noticed I can no longer send (compose new or reply) emails using this account on my phone. I get the following message in the email I attempt to send:
message status message included an invalid address
I can receieve my gmail messages on my phone no problem. My gmail account login information is correct on the phone.
I've tried searching for this problem but what I find always seems to be related to enterprise configurations using an Exchange Server and the fix was for the Exchange server. That doesn't fit my scenario.

Every time when I want to update I get a message that there is an invalid signature. I can't find any solution for that problem! Please help? It always stops during downloading and always the same message. According to what I could find it has something to do with error number(s) 3000-3099. But when I click on that I get a short message at the bottom of the page which says something about "an error on that page", so I cannot open it.

I recently bought a w890i locked to the Three network, and unlocked/debranded it using Omnius. I've done this before lots of times, so I know I didn't make a mistake. I have all the right drivers installed and I followed the instructions to the letter.However, when I finished, I noticed that I was getting an "invalid Sim" message. I tried unlocking it again but it didn't help - it said it was already unlocked. I checked the lock status using left,left and sure enough, it is unlocked. So just to rule out a problem with the sim, I tried a few different sims that I had lying around. The Three sim that came with the phone didn't work, and neither did the O2 or Vodafone sims that I tried. but an old Virgin Mobile sim worked perfectly. So what's the problem and how do I fix it. It's possible the problem was already there before I unlocked/debranded the phone but I never checked since I'm not on the Three network.I thought it might be a problem with the CDFS. I backed-up the TA and CDFS from another w890i as a precaution (like I say, this isn't my first time) but I never backed this one up beforehand believing that I could just use the TA and CDFS extracted from the earlier phone. However, now I've read that the CDFS is unique to each phone, so I'm wondering what I should do. What will happen if I try to restore the TA/CDFS from another phone? To be honest, I don't really understand anything about them.I've tried re-flashing the firmware, too. It didn't help. And there's nothing wrong with the firmware - I've used it before. I know I could get the original firmware back by uploading the old CDA and connecting to the SEUS, but would that really help at all?I'm a bit of a novice, in way over my head here.

I keep receiving this error message: "During synchronization, some of the records were invalid. The following 1 records where skipped: Address Book -0, Microsoft Outlook -1 Do you want to view the synchronization log for more details?" The sync log doesn't give me any clue, apparently there´s no big deal, but it generates the error and I also can´t sync with splash ID

Made the huge leap from a crappy reg phone to the 9700 a month ago. Its been sweet till all the errors started happeneing. Was hoping someone could help me out.
Here are symptoms as I've noticed them:
1) Wouldn't get audible notifications anymore. Now alerts, no alarms, no rintones,no nothing. Went to my ringtone/alert settings and did "TRY IT" to test a sound. The message I got was something about invalid filename. I got this msg even for sounds native to the bb device!
I did a battery pull, then all was good
2) Same issue kept re-occuring and also noticed my battery would be 75% full when I went to bed. Then like RED (5%) when I woke up. The device was also HOT! I battery pull again. Voila! (Until the next time it happens)
3) Press voicedial button. Then it says "scanning contacts, please wait" it gets to 100% and does nothing. Even after an hour.
Anyone know whatts going on? The only thing I changed during this time frame was the SD card (2GB to 8GB). So I switched back to the old card. Issues still exist. I even deleted soduku (buddy told me to try this) but it didn't help.

Whenever I run Ovi maps it keep showing me messages saying Memory full close some applications. I cleared history from the browser, moved messages location to mass memory. I checked if I have space on c drive from my laptop I can see that I have 150 MB free out of 276 MB. How I can get rid of this annoying memory full messages?

Yesterday I stopped receiving e-mail from my AOL account. Instead I received an "invalid credentials" message. I was sent to the email settings page and asked to enter my password. Did that...still get the same message. I found a thread in this forum (since have been unable to relocate it) where someone suggested disabling a need for two step authentication in google and another said to do a factory reset. how to do either of those two things.

Both my wife and I have Defy's owned for 4 months and upgraded to Froyo 2.2 some weeks ago.both working normally.Then yesterday my phone, for no obvious reason, came up with the message "Invalid Battery.Your device battery is invalid and cannot be charged. Replace the battery with an origional motorola battery." Also the battery symbol at top right of display is black, not green, and has a? mark in it. I have checked my battery, which came with the phone, and it is official Motorola with hologram. So is my wifes.I tried swapping the batteries and while my battery works perfectly in her phone, her battery in my phone gives the same errors.I then tried a master reset....Twice! Both successful, wiping all my data, and requiring me to set up the phone again, but problem still remains.

After taking the iOS 8.1.1 update to my iPhone5 periodically displays an "invalid SIM" warning. Not very often, but enough that it is annoying. If I turn my phone off, then back on, my SIM card is good and the phone works fine.Â
After waiting on hold for 45 minutes the apple care representative gave me this list of things to try... If you see 'No SIM' alert on iPhone Learn what to do if you see an "Invalid SIM" or "No SIM Card installed" alert on your iPhone.In some situations, the status bar on your iPhone might display No SIM, even though your iPhone has a SIM card. You might see an alert saying "Invalid SIM" or "No SIM Card installed."If you see any of the above symptoms on your iPhone, follow these steps:Update your iPhone to the latest version of iOS.Turn airplane mode on and then off again.Restart your iPhone.Check for a carrier settings update. Go to Settings > General > About. Install any available update.Remove the SIM card and make sure that it's a valid SIM that your carrier provided.
Also make sure that it's not damaged, worn, or modified. Then reinsert it.A SIM tray that comes with one iPhone model won't necessarily work with a different iPhone model. When you insert the correct SIM tray, the SIM tray should be flush with the device.If you have another SIM card, insert it. You can use a SIM card from any phone with the same format as your iPhone SIM card. If your iPhone works with that SIM card, contact the carrier that issued your original SIM card.Restore the iPhone.If you still see the issue, contact Apple support. I have just gone threw the "Restore the iPhone" step. We shall see if it happens again... Stay tuned!
