iPhone 4S is loosing connection with Carrier after iOS5 update

Marina, quanto mais pessoas vejo com o mesmo problema, mais aliviado fico,

pois comprei de segunda mão, e nem tenho nota para trocar meu iphone, que tambem é o 4.

o meu faz 10 dias, que voltou a só pegar a vivo. coloco OI, TIM e CLARO, consigo apenas usar o 3G

e pra meu azar foi bem no dia que chegou o 3G da tim na minha cidade...

vamos aguardar a proxima atualizacao e ver se volta a funcionar.

Tá louco cara, eu vou jogar essa merda janela afora. O pior de tudo é que desde que comprei o 4 (faz uns 2 meses, pq roubaram o meu 3GS) o sinal tá ruim, mas depois da atualização virou um iPod caríssimo. E só.

Espero que liberem a próxima atualização rápido =/ Os caras da TIM ainda me pegaram de TPM, coitados, enchi tanto o saco deles...

Torcer pra resolverem logo esse problema aí né, pq pagar caro num telefone pra ele não funcionar é ridí****.

Pior que nem adianta ligar em operadora. eles não estão preparados!

Na tim, apor confirmar todos os dados, sempre está inoperante o sistema. ou afirmam que eu sou um imbessil e nao sei usar o aparelho. aff.

na vivo ( onde foi comprado meu aparelho ) pra passar o imei, o atendente diz, "Senhor, retire a Bateria" Estão muito despreparados, nunca nem viram um iphone de perto, e isso que é só o smartphone mais popular.

Quando não te solucão te mandanm ligar pra Apple, que manda ligar na itautech, que manda ligar na peradora. é o "Apple-empurra-empurra"

ATé risquei a bandeja do chip de tanto poe e tira de chip, ja comprei outros e recortei manualmente.

pq Mini Sim eles só querem vender pra plano pós pago.

I live in Sao Paulo - BRAZIL

I bought the 4S 20 days ago and it worked fine in 5.0. With the 5.0.1 update it loses signal after 4 / 5 minutes on and after this gets failure on the SIM. I use TIM and already changed the SIM by a new one, already switched to a normal SIM and cut out, already put the chip from VIVO and CLARO, always with the same result as ****. I signed up for developers and installed the 5.1 beta. It's the same problem which leads me to believe that a new firmware will not fix it. Bought today a Samsung Galaxy S2 and will trow the 4S out the window. Long life to samsung.

Comprei o 4S faz 20 dias e enquanto estava na 5.0 funcionava normal. Com o update da 5.0.1 perde o sinal depois de 4/5 minutos ligado e depois dá falha no SIM. Uso a TIM e ja troquei o micro SIM por um novo, ja troquei por um SIM normal e recortei, ja coloquei chip da vivo e da claro, sempre com o mesmo resultado de bosta. Me inscrevi no developers e instalei a 5.1 beta. Acontece o mesmo problema o que me leva a crer que um novo firmware não vai resolver. Comprei hoje um Samsung Galaxy S2 e vou jogar o 4S pela janela. vida longa a samsung

Same problem here in Scottsdale Arizona. I'm on my 3rd iPhone4S and the phone won't hold a connection. The signal moves from "searching" to ATT to WiFi. The SIM card was changed and it still happens. I've taken in to Apple Genius Bar and they replace with new phone but after a week the problem happens again. It also causes the battery to deplete quickly and the phone to shut itself off.

Ola pessoal..

Tambem estou tendo problemas com o iphone 4s + tim no Brasil

Sendo que meu irmao tem o iphone 4s + chip pós-pago Tim e funciona normal ..a unica diferença é que o micro chip dele é mais antigo pois ja utilizava no iphone 4

Fizemos alguns testes hoje a noite..

1) Colocamos o meu chip no iphone 4.. funcionou normal

2) Colocamos o chip dele no meu 4s.. funcionou normal

3) Coloquei de volta meu chip no 4s ai deu pau..cai conexao..volta..fica fora do ar..etc etc

Pelo que da para ver tem algum incompatibilidade com o chip atual (retirei 3 dias atrás na TIM) com o iphone 4s..

Tem que ver o que a TIM pode fazer.

Tirem suas conclusões..

Hello everyone, try this and please report if it helped you too.

For me I solved the problem as it seems now... I was afraid to report because I thought the problem would come back, but it didn't, now already for a week!

My problem was: I lost connection to the provider every now and then. After that I did not get connection even on places where I had very good connection normally. Also one one of the SIM cards I tried now and then the no valid SIM popt up.

What I tried on the phone:

The flightmode for several minutes and back to normal which did not bring carrier connection back. I had to fully turn off the phone and put it on again, then it found my carrier again and connected.

I tried with and without WiFi.

Data on and off.

SIM pincode on and off.

Everything!!!

Tried to restore with backup several times.

Tried configuration as new Phone installation several times.

Tried with and without update to 5.01 and afterwards same procedures with backup and as new phone installation.

Also with different SIM cards installed.

It took me several days of restoring and testing! And I broke my phone-bumper after putting SIMs in and out several times.

What I tried on SIMcards:

I tried dutch providers KPN, T-mobile, Tele2 (on KPN) and Kruidvat (on T-mobile) (Tried 2 Simcards from them as one gave me "no sim" error also several times).

It took me 2 brandnew iPhone 4s (I returned the non functioning to Apple, after support could not help me)

I called my providers and asked for help, but it did not help. Also asked for 64k and 128k but this did not seem to be the probleme either.

What the problem was then, I don't know!

After I almost went mad and almost threw my iPhone away I found my solution 🙂

Settings --> Provider --> Turned automatic off -->iPhone searched for providers/ carriers and lists them --> select carrier. Thats all.

Ironnicaly: After travelling around with the settings like this (selected carrier) for a couple of days now, I now can even turn it back in carrier automatic selection and it does not lose its connection anymore! Even if I travel the same ways in railwaytunnels etc. It comes back to connection after a short no service in the tunnel and after that normal connection to my carrier again and never anymore no service!!

What happened????? Is there some spyware on the phone, some selflearning tools in the programming on the phone?

Dear dr e a:

When I saw your post I had a very special feeling and got very happy because when you described your issue it was exactly the same thing that happens with my iphone 4S.

Unfortunately, the happy moment last only 10 minutes.

10 minutes is the time that my iphone 4s lasts to loose signal and show no service.

Turn automatic carrier search off did'n work for me. Anything work for me.

In the firmware 5.0 my iphone 4S worked perfectly.

Apple where are you ??

Missing Steve Jobs!!!

Just forgot to say in the post above that I live in Sao Paulo - Brazil and my carrier is VIVO (Pos-Pago)

I like it!➕

Apple where are you ??

Missing Steve Jobs!!!

o seu está funcionando qual operadoa? nenhuma? o meu só pega a vivo. e uso tim e oi

I have registered this as a bug on Apple's radar (http://radar.apple.com). I was contacted by the engineering team and asked to reproduce the issue and send some logs from the device baseband. A few days later the bug was marked as a duplicate.

This means Apple's engineering team is aware of this exact issue and looking for a fix. Hopefully to be included on next firmware release.

(I'm in Brazil, TIM and two of four 5.0.1 iPhone 4S I got on France launch day are non-working with any SIM card. The other two are working fine)

I sent a email to Tim Cook about this problem.

Yesterday a man of Apple call me, and told me that apple will not do anything about this, because the iphone 4s didn't was launched in Brazil yet.

I'm really dissapointed

DR e a,

I read your post and I was so excited to start using my 4S again using your tip. I turned of automatic, BUT it still doesn't work. Still losing signal on my 4S.

I'm like a kid who can't sleep, sitting in front of a Christmas tree, waiting for Santa to bring Christmast present from Apple, an update to fix this issue :| and I'm not even christian/catholic 😟

.......

Now, stop works ALL Brazil CARRIERS . only works 3G.

voice no more.

Any body have a samsung. i sell my iTrash 4 ( iphone trash )

my iphone 4 is a ipod with 3g😠
