Hello jongriff1983,
Thanks for using Apple Support Communities.

Try turning iPhone off and then on again.
Remove the SIM card and verify that it is a valid, carrier-manufactured SIM. Also verify that it is not damaged, worn, or modified. Then reinsert it.
Check for a carrier settings update. Tap Settings > General > About while connected to a Wi-Fi network. If an update is available, a prompt should appear soon. If Wi-Fi is not available, connect your device to iTunes.
Update your iPhone to the latest version of iOS.
Restore the iPhone.
If you're still experiencing No Service issues, contact your carrier to check for any network or account issues that could cause this issue.
Best of luck,
Mario

Why is my iphone 4s saying no service all the time?

I brought a Iphone 4s on ebay they said it had no signal and the image showsed it was connected to the carrier but no signal bars. when i got it is says no service why. it is a o2 sim same as what they had.

So what did o2 say when you called them?
Part of many problems when you purchase a iphone from a non authorized dealer.

Can anyone help: my iphone 4 says no signal all the time

Hey guys,
Can anyone help me? I have done a factory reset on my phone and ever since, my phone will not regester any signal what so ever.
It just says "no signal" all the time. I have tried to reset network settings on it, but that doesnt work. Ive also tried to change carrier as it keeps telling me "your selected mobile network is restricted, you can choose a different network in settings." so ive tried every other network there is, but up until I did a factory reset it was working perfectly well on O2 if anybody could help itd be much appriciated.
Thanks in advance
Sarah

Marc,
Here's my story. Received iphone 5.... went to verizon and had them turn it on to my account. On to apple store to buy apple care. Put on Zagg sheild cover in the mall. Returned home. Played with phone.. no service. Tried to call myself via house phone.. no luck. No mail box set up. Can't set it up if I cant use the phone. Bummed. Called Verizon. He (David) suggested I return the phone to Apple store. Made an appt at the genius bar for the next day. In the store I had two bars, gal next to me had 4 bars on Iphone 4s with Sprint, Guy across had ATT with 3 bars. Now I had a new phone. New one was great - now had 4 bars in the apple store. Left... went to ZAGG, reinstall cover sheild then to Verizon and had them set it up with my phone number. Worked great while out and about.
Get home -- no service. Bummed again.... I checked the Verizon map and I was on the cusp of G4/G3. My phone was reading -- "o" and flipping to no service. David had told me he would call me back later that day, after I made a swap of my phone. David did call and suggest I get a signal booster. I placed an order for one. It arrived in two days, set it up - easy - and waited for all the lights to turn blue.... WALAA! Called the special number and the phone works great from home.
I get G3 service at home and when I am out LTE service. Funny - the LTE service light comes on right when I am exiting my driveway to the road. But I am glad that I have service from home. David called me again to check on how things worked out. So far I am good with my phone and service.
Signal booster from Verizon was my fix. Hope my story helps someone in the same situation.

The problem would seem to be in the firewall in your router. Have you tried disabling it? I assume you've updated the router firmware, right? Consider bypassing the ISP provided router (using it as a modem only) and unsing another device such as an Aiport Express.

My iphone 3 bluetooth is searching all the time

my iphone 3 bluetooth is searching all the time ,it is not working properly
ple solved this problems

That's completely normal. Everytime you open up the bluetooth settings menu, it will indicate the bluetooth is searching. It stops when you get out of the menu.

My iphone 4s shuts itself off all the time. starts normal and then shut it off and start all over again, what is wrong?

Your iPHone is designed by intention to shut off when there is a reason for the softwarer to believe that danger is immenent to the hardware. This can occurr if the software is running applications that have been corrupted due to all types of different scenarios. My best advice to you would be to restore your device back to default manufactures settings and do NOT restore the current backup of the IOS program currently running.
If this corrects the problem with your device intermittently restarting you will then know you have had applications there were corrupted on your device. Once you are convinced there are no issues with the hardware of your device you then are free to begin downloading software apps that were earlier on the device.
Good luck.

Network Searching or No Service All the time in my new iPhone 4S

Suggestion required how can I sort out the problem of No Service or Network Searchin all the time in my new iPhone 4S? It's really horrible to have iPhone in hand could not able to use that. Solve It soon.. Needs support on this issue.. Getting mad..

And just where did you get the screen repaired? Apple does not repair screens, they replace the entire phone. If you had it done by a 3rd party, then I'd say they most likely borked something up. Take it back to them. If the phone was actually replaced by Apple, then you have a 90 day warranty or the balance of the original warranty, whichever is longer. Take it in and have it looked at.
If it was repaired by a 3rd party, you are no longer eligible for a discounted out of warranty replacement from Apple.

IPhone 4s looks shut down all the time.especially when the 3g is on.in the forums its said to push the use button and the power button at the same time.the people calling me cannot reach at my phone.what should i do ?

my phone looks like offline all the time.its all about me to notice that its offline.then i have to push the main button and the power button together to open it.then the apple sign comes on the screen and the phone turns online.but i cannot receive the information of who called me at the time that my iphone 4s turned offline by itself.i cannot receive messages at all.what can i do now ? i sent the phone to the service and they just told me that they installed the current version.but i guess nothing happened.its doing the same thing again.i cannot use my iphone.
From Turkiye.

I've tried all those.But nothing works.The phone seems to be shut down.But it is not.When i get it out of my pocket, for example to call someone, i touch to main button but nothing happens.I solve it by pushing the power button and the main button together just for a couple of seconds, as its said so in the forums.
also, people told me that they were calling me, my phone was ringing but i didnt answer?...i checked it for millions of times, it seems to be shut down, but its normally not.then i push the buttons together and the apple sign comes on the screen.it searches for the network.and it works.
but i do not see any calls, texts anything.but for the others, they say my phone seems to be workin.
I thought it was 'cause of the 3G is switched on but when I turn 3G off, it does the same thing.it seems to be offline all the time.

Has anybody experienced the iPhone off switch not working all the time.

I have an iPhone 5, it's about 16 months old and it has experienced an annoying issue. The off button does not work all the time, sometimes I have to press it multiple times and other times it just works. The worst case is when it does not work at all, very frustrating. I didn't expect this type of issue for a phone that is not even a year and a half old.
I did some searching on the internet and there are 2 schools of thought, the first is that this is a hardware fault and Apple know about it but won't admit it because it would cost them too much to repair/replace phones with the issue. The second school of thought is that it is a software issue and a backup/reset/restore will fix it; I tried doing this but it did not resolve the issue.
Further digging seemed to suggest that it was really a hardware fault and the only option was to get a refurb from Apple for a ton of money, not cool.
Anyway, if anyone has any more information that could help me resolve this issue I would greatly appreciate it.

@diesel vdub, thanks for your suggestion, I setup an appointment with the Genius Bar and found out in about 5 minutes that everything I have read up on so far is true.
Firstly the technician admitted that there is a sporadic fault on the iPhone 4s and iPhone 5 switches, something to do with the design of the switch that included a rubber element that rolls up (whatever that means) and causes the switch to fail. He then indicated that the iPhone 5s does not have the issue because the switch has been completely redesigned.
Since I was stupid enough to not take out the extended warranty the only options he gave me were to purchase a new phone or to get a refurb for $269, not cool. Why would anyone think that a phone would not work correctly for 2 whole years when the phone only cost about $600!
Since I have about 7-8 months left on my phone contract I am not prepared to pay for either option. I find it amazing that a phone can develop this type of issue in such a short time and then expect the customer to pay for their failures. Apple supposedly sells a very high quality product for a very high price, looks like they have taken a step back from this philosophy.
I am disappointed in the options that he gave me (I don't blame the technician) but I suppose I expected more from Apple in terms of quality and service.

My IPhone 4S says No Service in the top left hand corner

Why is my phone saying no service in the top left
Hand corner ?
I just purchased this phone last Monday it worked grate
Then then it all of a sudden stated no service in the
Top left corner I'm not pleased

That could be loss of service from the carrier, or possible switching off of the iPhone cellular service or failiure in the iPhone itself. Go to Settings > General > Cellular and see that it is switched ON.
See also that Settings > Airplane Mode is switched OFF.
If both are correct, do a reboot by holding both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if it appears.
If that doesn't help, then you need to make an appointment at an Apple store genius bar to have the techs test the iPhone for failure.

HT3887 Hi I have just got some new wWas iireless head phones and when I use them with the Bluetooth on my iPhone 4S it breaks up all the time even from short distance but when using my girlfriends iPhone 5 or iPad it's fine no problems atall!!! Any ideas

Hi I have just got some wireless head phones and while using Bluetooth with my iPhone 4S the sound breaks up all the time but if I use a friends iPhone 5 or my iPad it's fine no problems atall! Any ideas what the problem could be people??????

Unpair the headset from the phone with the problem. Restart the phone (hold HOME and SLEEP until an Apple logo appears), the pair the headset again. Also, look for things nearby that may be causing interference in the Bluetooth band. Cordless phones are a common cause of interference.

HT4528 My phone says its charging all the time but wont turn on

My phone says its charging but wont turn I have it plugged in all day long and it just continues to show the low battery on the front! About every 6hours it will turn on for 5 minutes then shut right back off! Idk what's going on please help! All the support things on here want my serial number but obviously I cant get to it since my phone wont turn on!!

Hello Monica121,
Thank you for using Apple Support Communities!
It sounds like the phone will not boot or load up even after being given sufficient time to charge.
I had a couple of recommendations for this issue:
First reset the device with this procedure.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
From: iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists after that, then I would try these steps from the iPhone: Hardware troubleshooting article found here http://support.apple.com/kb/TS2802.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Cheers,
Sterling

Iphone 3gs says no service

Even after powercycling repeatedly, resetting network settings, resetting all settings and replacing SIM card, my iphone 3GS still says No Service.

Here's what you do
1.Make sure your phone is not plugged into the computer.
2. Put the iPhone into recovery mode (this is NOT DFU mode). Do this by
     a). Hold down both the power/sleep button and the home button until the screen turns black/off
     b). As soon as this happens release the power button but NOT the home button
     c). If done correctly then the Apple logo will appear, KEEP HOLDING THE HOME BUTTON and eventually a connect to itunes graphic will appear. You can release the home button
3. With the connect to itunes graphic on the screen, plug your phone into the computer. iTunes will start up if it is not already on, and then will say the phone needs restoring. Ignore this and COMPLETELY quit iTunes.
4. With iTunes off and the graphic still on the phone screen, hold down both the power/sleep and the home button again for 9 seconds (count 100, 200, 300...) or until the screen goes black
5. When the screen goes black release the home button straight away.
6. It will start up with the iPhone activation screen ignore this. iTunes should have started up, if not do so. Go to the iPhone tab and either resotre from backup or set up as a new phone.
You're welcome

IPhone 3gs says no service and cannot activate it.

I am trying to activate my iPhone 3gs and it says 'No Service' and when connected to iTunes it says that there is no sim card installed. I think it is on i.o.s 5 but not entirely sure as i bought it off of eBay and fixed it.
When i try to activate it on wi-fi it says the activation server is currently down.
Thanks for any advice you could give me on how to get it working
