I just had my SIM replaced: right after putting it into the phone the issue pertains I am still unable to make calls receive sms and so on. Only restart of phone helps for like 3-5 minutes.

Sounds prettymuch like my problem. I have reset my iPhone 4S to factory settings but it didn't help. The same problem occurs after. I use the sim in my old 3GS and that works fine.
Haven't tried the change of sim but hopes for a 5.0.2 fix instead...

Same issue with me, you can use the phone normally if you turn off Cellular Data setting (Settings > General > Network). You can still access the Internet through WiFi without facing SIM failure issue every 5 minutes
This is a workaround which worked for me. But for sure I am waiting for Apple for at least to talk about this issue.

Seems to work for me so far....
Makes the waiting for the right update a bit easier although I find it still a major bummer.

Same thing for iPhone 4S bought in Canada unlocked and being used in Argentina with Movistar. Today I changed the SIM card. Problem persisted. Battery drains FAST even under 5.0.1. The worst thing is that I recommended a Blackberry user to jump to iPhone and he's incommunicated. Tried disconnecting Cellular Data and it seems to be working since I started to write this blog entry. After 40.000 views and reports from all over the world and carriers Apple is still doing anything?!

Just as an update problem persisted even with Cellular Data turned off. Now I have a phone that doesn't do what it's supposed to do but everything else! The worst became a reality!

Друзья, русские, перечитав половину форума, пришел к выводу что нужна новая симка на 128кб. на украинских форумах ( а я из Украины) люди тоже приходят к такому выводу.

I have the same problem. I bought the iPhone 4S unlocked in Canada and use it in Brazil with TIM carrier.
I cutted my old sim card to fit into the iPhone trail. Tomorrow I'll by a micro sim card, change the old one and see if it works without problems.

I have the same problem. Called Apple Care in China just now. The first lady couldnt solve my problem so she got me a "senior engineer" to answer my question. I told the guy I started to experience the problem after install IOS 5.1. The "senior engineer" insists there is nothing wrong with iphone 4S nor IOS 5.1. He claims the no signal problem is a result of the current mobile network in China being incompatible with iPhone 4s, as the model is currently not out in China yet.
I don't know if this is true but don't think all of us having the same problem share similar background (i.e.brought back iphone 4s from another country, as iPhone 4s is not out in where you live yet)...

mine is out in Poland and I bought it from polish T-Mobile -> so no, that's rather not the problem.
It's the phone and/or software.

same problem happened to my unblocked Iphone 4S brought in Italy and being used in the same country.
When I bought and connected to internet, immdieately updated to IOS 5.0.1, so I didn't experience that passage with 5.0.0 no error but with 5.0.1 there is error.
I would like to point out it seems that this problem is linked to the acttivate/disacttivate sim PIN.
when i put the new sim card, I switched off the sim PIN function, it took very long time to apply my request, then the signal bar disappeared, saying "searching network". after few hours, arrived this error.

Друг из Украины! И где же ее взять, эту 128Кб-ную карту? Киевстар ничего не знает о таких, например...
Currently Being ModeratedNov 23, 2011 2:48 AM (in response to Barin)
Thanks, no 128Kb SIM in Argentina for now. Still this is an Apple software problem. iPhone is a GSM phone and that's it, it's expexted to work and accomplish that basic function.
