My iPhone 5 loses signal on the Vodacom LTE network. Is it the network or my phone playing up ?

When I put in Airplane mode and back it seems to fix the problem. But this is very annoying and not what I would expect from the NEW iphone 5. I have read a lot about this issue but NO SOLUTION

Why My iPhone loses signal when I had signal in the same place?

My iPhone 4S is locked with a Mexican company named "Telcel" and sometimes when I don't use the carrier network, it lose the signal for two minutes (but twice I had an emergency and I don't had signal). I tried to switch between 2G to 3G and the problem is solved… for a few hours. What's happening?

Hey thersjoel,
The passkey should be in the documentation for the devices:
Bluetooth headset: Refer to the documentation for the headset to determine the passkey.

Why does my iphone lose signal since upgrading to ios7

Since I upgraded to ios7, my iphone 5 constantly loses signal. It does so just about every 10-15 minutes. I have tried reseting my network settings, I switch to airplane mode, I do a hard reset. And nothing works. Prior to upgrading I never had this problem, now its constant. I am going to try to get a new sim card, but since this only started when I upgraded (almost the exact moment), I dont see that fixing it. I have to try to resend almost every text message, and safari pages never load. I have even been trying for days to post this question, but finally gave up and used my computer. I would really appreciate any help

Perfect.
With a iPhone keyboard lag since installed iOS7,
thanks to pvonk who said :
"Settings>General>Reset>all settings"
and it's go on very well....

Iphone 5gs signal strength - turn of LTE

Another post suggested turning off cellular LTE on the iphone 5gs to fix the low signal strenth issue - WORKS. immediate change from 2 - 3 bars to 4. He said he thinks this is a carrier problem - not the iphone. I use ATT he used another - I think Verison. Thanks

LTE and HSPA+ ("4G") are separate networks. So the strength on either one can be weaker or stronger than the other, depending on location of the towers. On my 5S near my home LTE is stronger than 4G. Where I work 4G is stronger than LTE. But even when 4G is stronger LTE is still faster.
Verizon is different. Verizon doesn't have an equivalent of HSPA+; the alternative to LTE is EVDO, which is a CDMA protocol and is quite a bit slower than HSPA+ on AT&T. Verizon's LTE was once very fast, but due to their success their network buildout has not kept up with the increasing load, so LTE on Verizon is quite a bit slower than LTE on AT&T or T-Mobile in many areas.

Iphone loses signal then cannot refind it.

Hello,
If my iphone loses its signal for any reason it cannot then refind it, unless I turn it off and then on again. This happens if I use airplane mode, or if I pass through a no-signal area (this happens frequently, unfortunately, I live in a remote place), or sometimes even if there is a brief signal interruption.
Obviously turning off and on is no great hardship, but if I don't notice then I miss calls when the signal is absent.
Is this some simple probelm to solve, or is it a tricky one? Anyone else had anything similar?

Hooray! Seems to be sorted by 5.1

How Can I choose Iphone 5s models that work with LTE in Brazil. The Iphone needs to Support Band 7. If I buy the wrong model can apple change it ?

I am planning to buy an Iphone 5s in October, but I have to make sure that the model will work with the LTE services we have in Brazil. I know that Apple made 2 Models that support Band 7. See Below.
Model A1457*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 2, 3, 5, 7, 8, 20)
Model A1530*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); FDD-LTE (Bands 1, 2, 3, 5, 7, 8, 20); TD-LTE (Bands 38, 39, 40)
How can I make sure I will buy the correct model through the internet ? Can Apple change the Iphone In case they send the model that does not support LTE services in Brazil ?
Thanks,

Have you personally tried those models with Brazilian LTE networks? Do they work? If so, fine. If not, then besides that, there is the problem of the warranty which is not international. The user will have to return the phone back to the country of purchase for both warranty and out of warranty service. So what might seem cheaper at first glance might not be in the end.
Anyways, it your money and the OP's should he want to go ahead with your recommendation.

IPhone loses signal and dosen't get it back

This problem started maybe 2 weeks ago and nothing has seemed to fix it. In my daily moving around there are many areas where I know I get no signal. At work, in my basement, some other areas of the city, and various other small locations. But it would generally always get the signal back pretty quick when I moved outside of my work buiding or am not in the basement of my house.
Recently though when I move to get a signal nothing happens. I have left it to sit for long periords of time where I know there is full signal and it never get the signal back. I go outside and still nothing. The only method that works is for me to turn it off and then turn it back on.
So far these methods have done nothing to help or solve the problem.
-Restarting
-Switching to Air Plane mode and then back off
-Restore
-Turning off edge and then back on
The only thing that works everytime is for me to turn the phone off and then back on. This is a total pain in the *** to have to do all the time. Is there anything else I should try or is it time to call apple?

Yea that is what I figured I would do. Although my iphone is now ~5 months old so will they still replace it? I thought they would only replace them if you were within the 14 day period, and they would only fix it (or attempt to fix) if past that. I guess if there is nothing they can do to fix it then it will get replaced?

Iphone lose signal and can't take it back

Hi all I've upgraded to IOS5.01 my iphone4 and if the iPhone loses the network it does not reach it anymore giving no service, if I put it in offline mode and then take off, the notches appear at most of the network without next to the word "VodaIT ".... the only way is to switch off and on again
Someone has heard anything about this bug?
Thanks!!

Hopefully the above link will help you to understand the regional models and allow you to decide whether your model is appropriate for your area.
I believe that a software upgrade (if you search these forums) should help you in any case.
Edit: I'm not familiar with your Carrier but I know they all handle BlackBerry in their own way.

IPhone loses signal for several minutes?

I had AT&T before I got my iPhone and I know of certain areas around my neighborhood where the signal is weak. My old phone would sometimes drop a call in those areas, but seconds later, the signal meter would start to refill as I drove into a stronger signal area. With my iPhone, it completely loses the signal and displays "No Service" in the upper left of the screen. However, even as I pass into an area that I know has a better signal, it will stay on "No Service" for about 2-4 minutes before it finally finds the signal again! Anyone else notice this?

More information on my reception problems. I am now absolutely convinced that it is a either a tower problem or a SIM problem - AT&T problem not strictly iPhone. I spent several hours today swapping SIM cards around between the iPhone, Nokia N95 and Nokia E61. In all cases I did the testing in exactly the same location within our house. Here are the results:
iPhone: Signal strength varies from No Service to full bars at this single location in a random, completely unpredictable way. While on a call signal strength was 4 bars and during the conversation dropped to No Service and call dropped. Later my wife called and was sent immediately to voice mail. She then called me on the landline and I checked the signal and it showed No Service. When it goes to No Service it sometimes takes a few minutes to re-acquire just like others have reported here.
N95 with iPhone SIM card: Signal strength varies from one bar to full bars in a random, completely unpredictable way. But never actually lost service. I tried several Edge data connections and while slow when signal was low none failed. I do not remember seeing this random fluctuation in signal on the N95 before with my old (pre iPhone) Cingular SIM card but perhaps it was there and since it was still usable I just didn't notice.
E61 with iPhone SIM card: Pretty much the same behavior as N95 except no full bar signal strength showed. Completely usable.
I realize that the iPhone will probably never get as good reception as the Nokias but I think if it would quit the signal strength variation or tower hopping or what ever it is doing it would be usable at even 1-3 bars if the signal remained steady.
As another point of information in case Cingular and T-Mobile are sharing towers at my location, I returned my T-Mobile SIM card to my N95 and tested it in the same location as before and it showed a consistent full bars with no variation and perfect operation.
Unless something good happens to solve this problem soon, I think that when I find a reliable method or service that will unlock the iPhone I am going to do it and go with T-Mobile. AT&T is not ready for dependable operation at my location with the iPhone.

Locked iPhone loses signal?

I have a password protected iphone, and everytime I'm at my house and it goes idle and locks I lose service. This causes me to miss calls, get text messages hours after they were sent, etc.
However, if I'm sitting down with it unlocked doing something on it, service is restored.
Anyone know why this would happen?
This is for an iPhone 3G that's about 5 months old.

That's interesting, it seems like the when it is plugged in it is helping the signal level just enough to stay connected.
All Smartphone, Ipad and tablets in general have to make the antenna's fit into a compromised environment to start with.
When we set up long range WiFi systems we have to use specialized high gain dedicated antenna's to get outside of the devices.
If your interested have a read up on how S/N (Signal to Noise) ratio's work on RF systems and you quickly find out how compromised our devices are right out of the box. It's the price we pay to have it all hidden in a pretty case
Cheers!

My iPhone 4 still seems to lose signal even though its at the latest OS?

As you can see from the title the Iphone loses signal whenever the antenna is covered. This problem I thought was resolved with 4.0.1 update? I am now at 4.3.3 and having only gotten the iPhone a week ago it is a big problem. Any help?

No, the phone quite clearly doesnt work fine, if i am on the phone to somebody I lose connection. That doesnt sound fine to me. And theres only one option and that is to spend ANOTHER £30. Could it not be that the antenna isnt set properly? I know apple was giving away free bumpers for a while but thats over now. That suggests I dont need a bumper to fix the phone as it was meant to be a software problem. This hasnt been fixed so im wondering if it could have something to do with the manufacturing.

Hi,
I purchased iphone4s in april 2012, people used to say why is your phone always switched off. when i visited apple store, they checked/disgnosed and told me that the signal is dropping and replaced the phone in july2012.
Recently, after march2013, i again visited the store and replaced the phone again.
now with the new peice, i am unable to get the calls, till recently i used to get calls for my job oppurtunities, but with the new replacement, i am unable to know, if it a problem with the phone or ishould move out of apple after all the embarasement for a year.
i have all the apple gadgets, but iphone4s really ***** my life.i have told them that i will pay the difference amount for iphone5, but the store guys says they cannot. with this problem, they now sold me a protection plan for 60 pounds.
I think, apple really ***** after steve jobs.if apple does not respond i am sure i will move to samsung 4

I have iPhone 4. After I upgraded to ios5 I have a problem with Wi-Fi connection with "WPA enterprize" protection. I can define the connection and everything works fine. But after I lose signal or shutoff the WiFi, I cannot re-connect, and need re-define

Is the battery drained after it shuts itself off?
Did you already try to set it up as new device?

Why does Find my iPhone lose the signal

Why does Find my iPhone lose the signal at times and show whre it was maybe an hour ago even though the iPhone is still on?

Without your password it would provide no security and anyone could then hack into your phone if the found it or stole it.
