Dec 23, 2011 9:02 AMby arturofromméxico,Yes, it is a very sad situation. I tried the Jannee/Jose Geraldo and Stefan procedures... twice. Only a few hours of phone. Today, another deception in the morning. I´m giving up. Today I´ll try to change the phone, but here in Mexico is harder that it looks on the US. I hope to be lucky and found today a friendly, happy, strong Christmas spirit fellow in the store. Thanks to all who share their experiences here! And Apple... come on, what is happening with you? We´re asking not for an immediate solution, only for a small piece on information!

Dec 23, 2011 2:00 PMby Neubrand,I was having the No Service problem during 3 days with 2 new Iphone`s 4S
bought at the online apple store.
Did the path update to 5.0.1 (****406) and still had the problem.
Today I changed the (normal cuted sim card) to the new micro sim card.
And believe me, the Iphone`s 4S are now working fine !
5 hours without any problem

Dec 24, 2011 1:53 AMby capitangiaco,HI all
I have 4s 32GB and INWIND IT microsim.
I see the 'sim failure' message randomly, a turn off and turn on of the phone fix temporary the problem.
Another thing that I noticed: sometimes (lately more often) I have full antenna signal on the display, I try to make a call, the antenna signal vanishes and it appears searching, after 30-60 secs the antenna signal come back I and can do my call.
About 2 or 3 min to do a call, not bad for a phone...
I think that this continue search for signal use more battery and we know how the Iphone battery life is short...

Dec 24, 2011 7:36 AMby cygn,THis other threat on "invald sim" seems to have a hack around mobile data and resetting the sim pin number
https://discussions.apple.com/thread/3497527?start=120&tstart=0
by the way, having a proper micro sim doesn't seem to make a difference - and the tape hack posted above does not seem to work - at least it had no effect from me running the 406 update.
am trying the sim pin hack from the above link.

Dec 24, 2011 1:46 PMby Inksmith,I activated my new 64gb wednesday, actiated it and it was fine all day. At 3pm the next day, the SIM failed. I had to get on AT&T chat to get the issue fixed. The solution was as listed above and odd. Remove SIM, put in old phone, then swap it back again, fine! Friday, again at 3, SIM failed. I went to the nearest Best Buy since that was advised by AT&T, and they put in a new SIM, fine. So far today, Saturday, I've made it past 3 without any issues. Hoping the new SIM fixed the issue because trying to get a 64gb replacement over the holidays will be next to impossible!

Dec 24, 2011 5:43 PMby killcity,iPhone 4s, unlocked. Worked fine in the states with AT&T sim. Now I'm in Prague for two weeks, using Vodafone sim and having nothing but trouble. First I woke up to "Invalid Sim". I then noticed the size of the hold contacts on that sim were much bigger than the AT&T sim. I taped over the spots that didn't seem to be used (basically sizing I down to the same as the AT&T sim). That seemed to fix the "invalid sim" problem, but now I'm losing the 3G indicator or it's going into "Searching" loops, then finally common back to the proper "VF CZ 3G" status.
The AT&T sim always worked fine. This has to be an issue with the sim or the antennas handling the signal ( not sure of the dual antennas work differently out here). I'm going back to VF tomorrow to see if I can get a "modern" microsim with the same contacts footprint as my AT&T sim.

Dec 25, 2011 12:51 AMby maverickjatt,A new 128k sim, properly cut with adequate margins on all sides did the trick for me..
I too was very annoyed because of this problem, but now it's been a good 10-12 days since i last saw that dreaded message.. hope this helps..

Dec 26, 2011 6:41 PMby Fastnine,For Verizon 4s users This problem is 150% a sim card problem..I had my phone since the day they were released and have had No problems untill 3 weeks ago.The phone would say"SIM FAILURE" at random times and most in the morning when the phone sat all night in the table.I tried all the fixes before i went to the store and had them change the sim card.What i noted was that the new sim was not the same as the one that came with the phone and the gold contacts pattern was not the same.It has been 5 days and the problem has not come back.The phone had the 5.1 update for a month before the phone started acting funny the first time ,so i can say it was never the update that cused my problem.I wasted a few days messing with updates and hard resets.Dont waste your time get a new sim first then go from there.
