IPhone losing signal

Hello there. I am having huge problems with my iPhone 3G and looking for some advice or help. My iPhone keeps loosing gsm signal and i get no service message in the top left corner. I tried hard reboot and switching airplane mode on and off. Also tried resetting network settings. Nothing seems to help.
It all started happening while I was on 2.2.1. After that I switched to 3.0. beta which solved the problem. Then I switched to 3.0 regular and it was OK until i installed ippc file in order to enable tethering on my iPhone. Does anyone know what can I try to solve this problem. It' s getting frustrating. No one can reach me for hours and calls keep droping. Thanx!

Hey guys, sorry to jump in so late here, but thanks to Google I found this thread. The past 4 weeks my IPhone 3G has been terrible. Full signal one minute "searching/NO SERVICE" the next. It's VERY frustrating. I just took some advice here and pulled out my SIM card and inspected it/reseated it. All looked fine. After that I deleted a bunch of apps I wasn't using. SO FAR it's been 3 minutes and the phone hasn't lost it's service. That's the longest it's worked in weeks. I've been rebooting my phone 30-40X/DAY. If it continues I'll bring it to Apple and see if they'll replace the SIM Card.

IPhone losing signal and have to turn on and off to get signal back

Becoming an issue which is very annoying.

Basic troubleshooting steps outline in the manual are restart, reset, restore from backup, restore as new. Try each of these in order until the problem is resolved. If you've been through all these steps and the trouble persists, you'll need to bring your phone to Apple for evaluation. Be sure to make an appointment first at the Genius Bar so you won't have a long wait.

Sky HD box keeps losing signal but is fixed with a power cycle

Hi all, I'm having issues with my Sky HD box. Every day (recently), I'm having to powercycle the box to get a signal.After the power recovery the signal is fine, so I think the dish is fine. It's seems the the box is losing signal while it's on stand by mode. Any ideas? Thanks in advance Jason

I had this problem too but in the end the solution was for Sky to come out and replace the dish and LNBs, since when the signal has been perfect. I would check what signal strength you are getting - I believe it's in the settings menu.

My iPhone carrier signal strength is not good

I have a "case" open with Apple for poor carrier signal strength after upgrading my iP5 to iOS7.
Please make sure you open a case with Apple.

Iphone 4 signal fix

Steps
-- Read Anandtech article on iPhone 4 signal strength and identify location of antenna stops.
-- Take standard insulation tape and cut strips slightly thicker than metal strip and long enough to cover antenna gap.
-- Apply tape do the two locations using graphics from Anandtech article.

Sorry about that. Did not search properly before posting.

Component - Losing Signal Frequently

*I'm not using HDMI because when they installed HD FiOS on my TV, they said that HDMI wasn't working so they put in the component cables.*
I have been losing signal quite often, sometimes several times in the duration of a half-hour show. It can't be the weather because 1.) FiOS shouldn't be affected by the weather and 2.) this happens rain or shine. When the set-top box comes back on, my TV says that the box is in stand-by mode and to press MENU to watch television. It's become extremely irritating.
Thanks for any help.

same thing with me they said that HDMI cable wasn't working and said that they had to use component cables. Now Tonite i was watching TV an between 7pm and 9:30 the HD DVR cut out about 15 times....Must say I am royally upset!!!!
Does anyone know how to fix this issue???

Airport Losing signal/disconnecting

Hi,
I'm currently still having problems with my airport disconnecting and losing signal. This is really driving me nuts, is there any solution to this? As it was working fine till i updated it.
If anyone can help that would be greatly appreciated.

I had the same problem when updating to 10.5.6, i fixed it with a clean install. Before you do that you can try to isolate the problem further with these steps:
- What was that last thing you did before this problem started?
- Do you have the same problem no matter what network/type of router you try connecting to?
Just to make sure its not hardware, boot to your Leopard install disk and try connecting to the network from the airport pane. If you have the same problem when booted to the install disk its pointing towards a hardware issue. I would head for the nearest Apple store and make them fix it.
If you don´t have the same problem when booted to the install disk this might be cause by a software problem.
- Make sure everything is up to date. OS X, firmware for routers etc etc
- In System Preferences>Network, make sure the service order is set so that Airport is on top
- Is there any devices that can cause interference? cordless phones, microwaves and so on.
- Try changing channels on your router.
- Reset your router and set it up again. If your using a Airport base station go to Manual Set up and choose File from the menu bar, click Save a Copy as. This will allow you to export the base station settings, if you need to get this settings back you can simply import them.
- Rename /Library/Preferences/SystemConfiguration and restart your machine. This will remove any network settings you have made on your machine
- Create new network settings
If your not able to solve or isolate your problem with these steps i would suggest you post the Console logs here as there are a lot of the ppl on the forum that prbly can help you more after reading those.
Best o´luck

That's a preinstalled app that cannot be deleted.
Try swiping through your screens.
And try swiping left of the Home screen then type app store in the search field.

Has anyone having an issue with the iphone 6 signal cell strength on Verizon?

Is anyone having an issue with the iPhone 6 signal on Verizon?

I'm having the same issue as most of you on this forum. my current OS is 4.3.5 and after a factory reset, the camera started working fine, however, once i done the restore the camera reverted back to the same issue - "the shutter on the screen wont open, and the still/video switch just flashes" - what is more strange is, i have the HP home&biz app installed and this has a camera function and the camera seems to work fine with that, therefore suggesting there is nothing wrong with the hardware and this is a software issue. I'm currently awaiting a member of the Apple support team to call me about this, will keep you posted. BTW - someone suggested, going into Location Services and switching off the camera and apparantly, the issue was resolved for them, unfortunatly, this didn't work for me extremly odd issue indeed!

Have brand new iphone 4s. Wifi signal is very weak even when very close to router. I have also an iPod Touch and when both are side by side, the iPod wifi signal is excellent and the iPhone wifi signal is very poor??!!! Hardware issue? or software issue? I was hoping it is just a software issue, but...
Saw may web sites discussing this same issue; many discussions point to hardware problems but there is no official word from Apple about it, which is disapointing !?? Few discussions point to software problem with solutions based on try and error, and they don't seem to work.

did not help at all; the problem continues the same

Iphone 5, Perdendo Sinal (Losing Signal)

Bom dia, estou com um grande problema, estou com um iphone 5 64GB que foi comprado através de um anúncio que ví na internet, marquei com a pessoa e testamos tudo, acontece que o aparelho é importado e não tem NF, e estava tudo funcionando na hora, voltei para casa e estava normal, durou apenas algumas horas, pois o aparelho de forma aleatória, cai o sinal da rede e fica em tempo variável "BUSCANDO.." leva em torno de 30 minutos a 1 hora para voltar ao normal, fica algumas horas funcionando e acontece o mesmo problema, "BUSCANDO.." as vezes acontece de hora em hora. Não consigo mais contactar a pessoa que me vendeu.
Acontece que procurei tudo sobre EMEI, BLACKLIST, e não consegui chegar a uma conclusão, o aparelho ao inserir seu Nº de série no site da Apple, leio a mensagem : Desculpe-nos, mas este é um número de série de um produto que foi substituído.
Já testei Claro, Tim, Nextel, todas acontecem a mesma coisa, vamos aos fatos, se fosse problema de EMEI ou BLACKLIST o telefone poderia funcionar tantas horas seguidas sem apresentar problemas ? Pois quando está com sinal funciona tudo, Dados, VOZ, SMS.
Já resetei inúmeras vezes todas as configurações, já restaurei o iphone, passei grafite no chip, tentei "N" coisas.
Caso fosse algum problema da antena ou outro componente ligado a recepeção de sinal, porque funcionaria tantas hora e de forma aleatória apresentaria esse problema ?
Sou do RJ, e tem uma loja APPLE oficial aqui agora na BARRA, estou pensando em levar o aparelho ainda essa semana e tentar explicar isso, mas acontece que estou meio cabreiro do status desse aparelho, e fico com medo de eles bloquearem meu aparelho permanentemente e eu em conseguir mais usá-lo.
Ví também que tem muitas pessoas com seu EMEI bloqueado sem motivo algum.E outras que ao colocar o chip da OI funciona todos iphones 5 sem problemas, alguma alma nobre para tenta ajudar ? A única solução de imediato é tentar colocar um CHIP OI para testar a ocilação de sinal, e caso não, teria que levar a própria loja apple.
Grato, e aguardo respostas.
Good morning , I have a big problem , I have a 64GB iPhone 5 that was purchased through an ad I saw on the internet , marked with the person and test everything that happens the machine is imported and has NF , and everything was working at the time , came home and was normal , lasted only a few hours , as the machine randomly drops the network signal and is variable in time " SEEKING .. " takes around 30 minutes to 1 hour to get back to normal , is a few hours working and the same problem happens , " SEEKING .. " sometimes happens hourly . I can not contact the person who sold me .
It turns out that I sought all about EMEI , BLACKLIST , and could not reach a conclusion , the apparatus when entering your Serial on Apple's website , read the message : Sorry, but this is a serial number of a product that was replaced .
Have tested course , Tim , Nextel , happen all the same, here's the facts , if problem EMEI BLACKLIST or the phone would work so many hours without presenting problems ? For when is it works with signal , data, voice , SMS .
Have reseted all settings numerous times since restored the iphone , I graphite on chip , tried to " N " things .
If it was a problem of the antenna or other component connected to recepeção signal , because it would work so many hours and randomly present this problem ?
'm RJ , and has an official APPLE store here in BAR , I'm thinking of taking the set later this week and try to explain it , but it turns out I'm kind of suspicious of the status of this device , and I'm afraid they block my device permanently and I get to use it more .
Also saw that many people have locked their EMEI algum.E no reason other than to put the chip HI 5 iphones all works smoothly , some noble soul to try to help ? The only immediate solution is to try to put a CHIP HI to test the oscillation signal , and if not , would have to take the apple store.
Grateful, and I look forward answers .
