Hi guys,

I've had my iPhone 4 for two weeks now and have started experiencing an issue in the last two days.

The phone loses signal, says "No Service" and does not find reception thereafter. Nothing to do with the "grip of death" either - just find this message when I pull it out of my pocket.

Toggling Airplane Mode On/Off does not help. It says Searching and after a few minutes it says No Service again. Only thing that helps is to restart the phone.

It did this yesterday, so I restored the phone and set it up as new. Today it did it again. So I restored again.

Has anyone else had this issue?

Ok, and the only way you "fix" it is by restarting the phone?

I Googled around and see that a lot of people have this issue in the US and UK. Some have had their sims swapped, some had their phones exchanged and some just left it and restart them when this happens.

Also, this only started for me when I upgraded to 4.1. Didn't have any signal probelms whatsoever on 4.0.2
 
This has actually been happening with me using an HTC HD2, just the last 10 days or so and only in Midstream (Vodacom).
 
Experiencing the same occasionally. Funny thing, mostly at work. Clearly not a happy place for my phone. :D

That's what I'm wondering about - is it a network issue? Or sim car or hardware?

The thing is - all the phones I've had in the last two years would occasionally completely drop signal. For a few seconds, but then it would come back. The iPhone 4, on occasion, also drops signal, goes "Searching" and everything is back. But the "No Service" issue is more worrying, as it requires a reboot of the phone before it comes back. So if you don't notice it, you will miss phone calls/sms/etc
 
Exactly. I have also seen drops which 'fix themselves' after a few seconds, that is normal and I assume the network probably just takes a 'dip', but I am moving around to high signal zones around the office with no luck, only a reboot fixes it!

Sorry to hear that you have the same problem, but at the same time I'm glad to hear that I'm not the only one.

Makes me think that this is either a network problem or an iPhone hardware issue.

I'm thinking of maybe getting a new sim, but I don't know if that would help
 
Used to have this exact same problem on my old iPhone 3G. Would lose signal and stay at No Service until you actually rebooted the phone!!! It only happened at work though - never anywhere else, so I'm guessing there was something on the tower that my iPhone didn't like!! Had my iPhone 4 for a while now and haven't had the problem again...
Never really figured out what the problem was...

Personally, I do not think a new SIM would solve it though. Network... I'm no expert, but the fact that it doesn't recover itself unless you reboot, points all evidence to the iPhone, whether hardware/software.

Mine also ONLY happens at work. Clearly iPhones are made for playing and not working! :D

Really hoping its the software... Like I mentioned earlier I only experienced this problem after upgrading to 4.1. At 4.0.2 I never even lost signal for a second (that I noticed at least). Well, 4.2 will come out soons, since its already in beta 3. So we'll see. I guess if it happens ocassionally, its ok, but as long as it doesn't start happening every day.

Mine used to be very random - sometimes 2 or 3 times a week - sometimes once every 2 months.
Well, 4.2 in November - can't wait!!! :D
 
turn off 3G , and see if the problem still occurs

So my phone gave me the "No Signal" message again last night. I was listening to music before going to bed, everything was fine. Then I left the phone on my bed stand for a few minutes and then wanted to set an alarm. That's when I saw the message. Will take 3Gee's advice and see if that helps
 
Mine started with the "No Service" yesterday when i was on the phone, i am sitting with my iPhone currently with "no service" i did restart it 3 times now still "no service" anyone know what is going on?
 
I need some help. I have just got my iPhone 4 last week. This morning, it gave me a message sayin "springboard has crashed" and the phone rebooted, and I have the "no service" message since then. I tried swithching the phone off and on, I tried switching 3G off. Nothing is working. It cant pick up any signal. SOmetimes it shows signal but if I try making a call it says Call Failed. If I try to call my phone, I get my voicemail. What should I do?

Do any of you guys have Auto3G from Cydia installed btw?

Yes I do have Auto 3G, and incidentally, I have just come on here to post that I have turned Auto 3G off, and my phone is now fine. This problem of mine also like everyone else, started at WORK this morning :D so I can only assume that there is a 3G problem on this tower. And Auto 3G was automatically switching to 3G even though I switched 3G off. So now that I switched Auto 3G off, everything is fine :D
