iPhone 4S "no service" problem

Same problem here with iphone 4. About 1 month ago, my friends bugged me to update to ios5 so we could use the imessage ap. BIG MISTAKE!!!!!!!!!!!!!!!!!!! i had a feeling that there could be problems, and sure enough i got the worst problem of them all. ios5 = nice paper weight iphone. At first i would get about 3 days of use before the no service/searching bug would show up, and a itunes restore would do it for another 3 days. Now the phone is to the point that it wont make calls or send texts at all, even after repeated restarts, restores, anything. I should of stayed with ios 4.2.1. it worked perfectly fine.

is there any way to turn back old ios? i don't want to wait until apple gets out new ios version.

I am on an iPhone 4.

I turned off "CELLULAR DATA" and the NO SERVICE-SERCHING FOR SERVICE-SERVICE FOR A SEC problem has gone away.

It is critical to have Cellular Data for GPS and internet when not on a WiFi but at least I can make a phone call w/o it dropping.

Look in SETTINGS-GENERAL-NETWORK-CELLULAR DATA

I just got back from the apple store, talked to a great guy. Explaned everything ive done so far, and after showing him the problem, they replaced my phone , it was actualy a very plesent experience! Before i brought my phone in i did a icloud backup of my contacts only ( i have a suspision that the courrpted data could be in the itunes backup data.. So after getting. New phone, restored my contacts and so far so good! Hopefully it keeps on goin :)

So disapointed by the iphone 4S, I had the same experience by everyone else here. The phone had all the bells and whistles working BUT what it originally was intended for, which is to be a PHONE! Brand new out of the box straight from China and it wouldnt connect to the ATT 3G network, says Searching... No Service. I was on the phone with ATT practically all day and went to a corporate store where they tried a new SIM Card and no luck. Apple said it was ATT fault and ATT says its Apple's fault. Since my old iphone is working fine I am lucky enough to have another phone and ATT was nice enough to give me a new sim card for disconecting the old one to my old phone but this is rediculous. Where is the quality control APPLE from things comeing str8 from another country.

I am disapointed with apples customer service so far. I wasnt given the option to return the product and get my money back, after having it for about 12 hours only!! Where is the 30 day refund?!?! Anywaays I sent it back to Capertuno CA, to APPLE they better send me a new one, I feel like they are going to send me back the same one because they are fixing it under the warranty plan. Thats like paying full price for a refurbished apple. I hope they see this as an issue, the media is right Apple is slow to admit to failure.!!!

I called the Apple UK customer care although I do not live in the UK as I do not have an Apple retail store in my country. Anyway, I spoke to a very nice man who told me to ship my phone over and they'd send back a replacement as it seems to be a factory defect. I'm mailing the defective one tomorrow and should expect my replacement really soon. I miss it already!
Hope all goes well, and good luck to you all.

I hope to get this type of service here in the US! On the phone with APlle now trying to get this great of service.

I got a complaint against Apple myself. I go to my network carrier, buy the **** iphone 4s 32gb for a whooping 700EURO, go home, play with for a while, then crash, no service. I go back to the store the very next day, and they wouldnt give me a new phone, and told me it first has to go the tech people, and it will last min. 3 days. i mean what the **** Apple, this is how u treat a customer? he buys a brand new phone that breaks the very next day, and u make him wait another min. 3 days to get him back a new one (or possibly the same phone) .. seriously..

same problems in Czech republic - after update the phone is just an expensive ipod. changing sim does not solve the problem. after restarting the phone i have like 1 minute of network connection available, after that it gets lost.

I started with the problem last wednesday (9th november) whilst away, mate was sat next to me with iphone 4 with full signal no problems and mine kept dropping out none stop.

Fast forward to 15th november (i hadnt updated to 5.0.1 by this point), i had "no service" so took the advice and reset network setting and rebooted the phone. Once booted back up the phone was convinced it was fresh out of the box and wanted an itunes wired connection (3g/wifi not working) so i shut it down and left it for 10 mins, rebooted and all was back to normal - full signal as well.

17th november today running 5.0.1 as from last night and its been dreadful, no signal anywhere i go, emails, texts, phone calls are now pointless and im left with an ipod and some likely gloating from the girlfriend whos nokia has full signal everywhere.

Hope apple get 5.0.2 out soon as this is rather silly and has actually made the battery problem worse with the phone now constantly looking for a network connection (6 hours to a charge im getting at the moment!), who do apple they think they are? RIM?

i have bought my phone in late october and was using my old sim card, which i had been using literally for ages... it was the regular sim card where they had to punch / cut it to convert it into a micro sim...

prior to the 5.0.1 update i used to receive the "invalid sim" message every now and then but didn't got bothered since the phone was operable after a reboot... then last friday (11.11.11) i heard that an ios update was released so i updated my phone and went out directly only to face terrible network connection if any and was not able to communicate with my phone...

at first i thought it was a glitch because i was using stereo wireless bluetooth headphones along with every imaginable feature on the phone turned on... so i started to experiment by turning each feature off to find out which one was causing the problem... tough luck, and my situation did not improve one bit... then i started investigating about this issue and found out that there were quite a few people having the same symptoms... i tried every imaginable thing that was described on this and almost every other forum / discussion boards i could find...

i resetted the phone by itself, i resetted the phone a couple of times via itunes, i tried to reinstall the ios 5.0 via the ipsw file i found on the net, which did not work, i downloaded different 5.0.1 ipsw files in case it was a weird software issue with my downloaded file... nothing worked...

i never ever thought that this could be a sim card issue, since it already sort of worked prior to the update, then i read here from a couple of my countrymen (turkey btw) along with people from other countries, that they have solved the issue with replacing their sim card, my fellow turks stated that they have solved it with replacing their sim card with a 128 k microsim card to be exact... so i gave it a try and replaced my card on monday... they were right, i do not have any problems with my cell carrier network or anything in general and since the signal is stable and perfectly in order the battery drains less (if you have poor or no reception your battery will drain much faster)...

so, what i can advise you with is that you get your sim card replaced with a microsim, preferrably a 128 k one if your carrier provides them, it definitely solved my problem and believe you me, i have tried almost everything... 🙂

Hi, I have an iphone 4, updated to ios 5 everything worked fine before and after! Then updated to ios 5.0.1 and since then I have "no service" or "searching". If I switch the phone off and on I get signal for a short period of time. Then when left idle it goes to "no signal". This is so frustrating!!! Can't believe Apple aren't doing anything!! ;- /

Same problems here in Spain with my iPhone 4s. This has happened 3 times to me. First two times I had to restart the device, third time it came back by itself. Happened with both 5.0 and 5.0.1.

Same in UK with Orange. Facing "No service" all the time while same sim in years old Nokia E71 has no issues with helthy reception. I am so dissapointed with Apple really. So much hypes.

Same problem in Turkey, i can call 1 time and then signal off !!

I always restart my 4S ! why this engineers dont test the software first ??? Now cant sending msg also !! This is huge problem and apple must be find this solution ASAP !! Because people cant use their phone !! no msg no call no internet !!

We are waiting the solution please search and fix it quickly !

Thanks
