Iphone 5 signal loss

I did a restore from an iPhone 4S to my new iPhone 5. I had problems. Since doing a reset on network settings things have been ok.

now iP4 3 bars and iP5 no service...seems an iPod

Ok, now I'm seeing a pattern.

Like above I restored my ip5 from my ip4

Backup on the 1st setup.

Then the problems begun.

I then reset my network settings and problem solved.

And to be honest, I haven't plugged into iTunes from that day.

I see people above who restore many times but the problems persisted.

But doesn't iTunes backup then restore, wouldn't

This just fix/break/fix/break the network settings?

I'm sure it's something iTunes or icloud is doing to the phone?

Anyone having this problem please report it to apple bug report here

http://www.apple.com/feedback/iphone.html

Hopefully they will fix it.

Tried all efforts posted on here and nothing works.

Agreed Arthur. I've not done a restore since the initial setup of the phone from the backup. Too coincidental? I think not.

After searching the internet I have found this thread on here.

Im having the exact same problems. I have good signal but when im at work at my desk I lose signal. The first time I noticed this was when I arrived home and noticed that I had "no service". I just ignored it at first and after 20 mins I still had no signal (I normally average around 4 bars signal at home). I decided to switch the phone off and back on and then didnt think anything of it. Then the same happened again the following day and so on... The phone gets stuck on the "no service" until i restart the phone.

Im very annoting by this, I never had this issue on my iPhone 4 and although the iPhone 5 is a great piece of technology it doesnt actually serve its purpose... afterall, it is an iPHONE. I have missed about 20 calls in total and a good amount of texts because of this issue.

I phoned apple who adviced me to reset network settings, this didnt work. They then said restore the phone, this didnt work. They said get a new sim card, this also didnt work. They said start the phone as a new phone, and it still doesnt work.

I was in two minds about buying this iPhone and to be honest, I shouldnt have bothered buying it. Im visting the genius bar at my local apple store next week, not sure what they will do but obviously, this is an issue that Apple need to sort out and QUICK!

Ive just emailed this to Apple via the feedback page. The issue only seems to happen when ive had no signal for around 10 minutes or longer.

Just thought I'd add my experience. My 5 has been doing the same thing, gets stuck on edge requiring a reboot or airplane mode on/off to bring it back to 4g. I took it to AT&T and they tried a new sim which didn't help. Then I tried apple and got the ok for a new phone. I litterally just got home from the hour drive to the apple store and my NEW phone just got stuck on edge *banghead*. I have not been home yet to restore from my iTunes backup, aside from backing up my contacts from cloud, it's a virgin phone. I'm seriously thinking about just telling them I want my money back and a 4s. My 4 never had one issue in two years of owning it. :(

today apple replace for the second time my iphone 5,

signal seem a litte bit better bat the flash of camara it's broken

now i require the third replacement

Well I had the problem again this morning, so not completely fixed after all.

A quick switch to Airplane mode and back and all is well again.

Back to the drawing board, although I'm guessing there is nothing other than waiting for the fix to be released.

Field tests carried out between 5 and 4S side by side, the 4S goes from -89dB to -95 on 5 ranges from -95 to no service

I have the same problem, lives in Vancouver BC, Canada. Just bought 2 new Iphone 5 yesterday. Will get signal back after reset network settings, but then at home have to re-enter Wifi settings. Have same problem on both phones and by the way no I-cloud or I-tunes setup on these phones yet. I now went to settings-privacy-location services-scroll to bottom-system services and disabled all except compass,time zone,traffic as suggested above and will see how it works

I saw on another forum that the problem is with LTE signals. I now disconnect LTE(Settings-general-cellular-disable LTE) on the one phone and keep it enabled on the other phone, Both phones are setted as in my previous message except one now is LTE enabled and the other one not, so let see what is happening

Live in Connecticut and this has been a constant problem. As LTE is not in Connecticut yet, or at least the area I most frequent, turned off LTE last night before work. So far it seems to be working. I will lost signal momentarily inside work then it will go right back to 4G. Will give it some time and see what happens.\

This isn't an LTE specific issue. We in the UK don't have LTE yet.

One interesting, but I'm not sure how it's related point. I didn't get the issue today and I had Bluetooth enabled. Doesn't seem to have the issue when it's on. I'm in work now and have a signal, without having to go in to airplane mode.

Maybe it's not Bluetooth but the fact it's Monday and a bit foggy. Who knows.
