iPhone 4S dropping network and data at random

Hi unicohijo,

My phone was with the 5.0 version in late October. In mid November I did an update over the air with the 5.0.1 9A405 and the problem started to appear (not so frequently as now). By the beginning of December I did an update to 5.0.1 9A406 with no good results and these days the problem get it worst, not even an hour connected to the carrier.

Greetings

hi everybody.

i have iphone 4s and i have the same problems with the network but little bit different, that i rarely see full 3G signal bars !! i dont know if this normal in iphone 4s or i have some problem !! i see on my other blackberry phone full bars and my iphone 3 bars only !! at the same place !!

please , i would be happy if anybody give me an answer 🙂

thanks

For me the problem arises whenever i try to send a text or make a call. Most of the times my phone shows full bars but when i try to text someone or call, the network bars drop - switches to searching - no service - bars come back ! Now when i try resending the text or making a call it goes thru ! the phone works fine approx for 5 mins post that the cycle repeats !

I had notice that too, but I think those full bars you see are fake (the phone stuck in the last signal state). Have you ever tried to dial your iPhone number to see if is really working? I had and it sends me to the voicemail.

Hey Francisco,

I tried calling my own number, result the same - Call Failed - Network Drop - Searching - No Service - Full network bars !

DEAR APPLE:

THE MODEL MC918LL COMING FROM USA CAN WORK PROPERLY...

I DONT KNOW WHAT MAKES THE DIFFERENCE OF MODEL MD234C...

I SOLD MY OLD PHONE 4S AND LOST 300$ TO OBTAIN A NEW ONE MC918LL

WHAT COULD BE THE DIFFERENCE BETWEEN THEM? PLEASE TELL THE PEOPLE ALL OVER THE WORLD...

ITS WITH 9A406 5.0.1

IF ANYONE WANTS IPHONE 4S , BUY THE MC918LL MODEL...IT WORKS IN LEBANON

I don't know if that is the software or hardware problem. But in ios 5 my 4s works well. In 5.0.1 it didn't work with any sim except the one of my mother. It is a sim with big yellow chip. I tried another one with big chip but it did not work. I lended it to my mother and used the 4.

I think Iam lucky because my nearly 1000$ phone can make call with a sim. Many others cannot do it.

Apple should do sth more agrressive. I could not see any value from it since Steve went away.

9 out of 10 morning, I get up to SIM card Error message. This is my 2nd iPhone 4S. I am not happy. Not happy at all.

So you have already had your iPhone exchanged? Dont tell me that it didnt help!

I m currently having my iPhone 4S in the servise and I m hoping that will solve the issue! Otherwise, i m gonna be pretty fed up...

Always no solution my iphone 4s became in ipod now , got error about 6 time a day ,i buy this for about 740 euro and always no solution , we must do some thin guys !!! apple must fix this .... all was fine for me with 5.0 i did apple update 5.0.1 and from this date i am out out out !!! apple take action !!!!!! lets every one talk about this in tweeter facebook and all blogs , so no one will loose his money .........

same problem Ukraine (5.0.1 9A406).

Hello!

Also have this problem. IPHone 4S, 32 gb, 5.0.1 with newest patch. Look forward when Apple publish the new patch.

Mine had 3g connectivity issues for three months now. Tried 5.0.1 and latest build of 5.0.1

and it got worse. Now I'm experiencing complete network dropping from

my carrier. A popup shows the connection being lost. It's happening now

5 to 10 times a day at least. Very frustrating losing signal randomly. I'm waiting

next update to see if problems are solver if not i will ask for a replacement at my local Apple Store.

hi Venkat

Hoping you could help me out a little here.

I am from India too and on Airtel as well

Currently using the Mini-cut Out Sim, the first pic that youve attached and having a lot of problems.

Just wanted to tknow how did you get Airtel to give you the Sim shown in the third pic that works and also as in what did you have to say to them?

Also is it still working well?

Thanks for the help

Appreciate it

It is true. Our 'S-life' is not easy... .

After every 20-30 min in standby mode my 4S (5.0.1 9A405) is "currently not available" for other phones, although there is unbelievable full antenna bar on the screen. Every time when I try to make simple call, I spend from 4 min up to 11 min to make my iPhone 4S (with Dual Core A5 Chip inside) doing this "unusual" operation. During this "call preparation time" I have to push several times green buttons and I have to wait for the next reaction of "smartphone" and next right moment to make necessary touch on another green button on the Retina Display, that I might to get my telephone calling. But I am pretty satisfied with this procedure, because at the same time I can watch nice real time movie: Full antennas bar goes to 'no bars', then after while it goes 'searching' , then 'no reception', then 'searching' etc.. If I make no calls within approx. 10 min after my last call, I have to go through "call preparation time" again. O.k., may be it is not so exсiting, but at least it keeps me busy whole day... .

But, Gentlmen,

finealy I have found the solution!!!

It is so simple: Just connect your device to power supply and all network problems are gone!!! (no joke!)

P.S. At the same time you have no problem with battery life time!
