I live in a poor reception area on the Rogers network. I've noticed that when I go into the basement the phone drops a signal pretty quickly. I am okay with this and is expected. My issue is when I get back on to the main floor, the phone does not pick up a signal again for a long time. Sometimes even toggling airplane mode doesn't work. My wife's iPhone does the same thing.
Anybody else having this problem?
Recently, I began to have this problem where the phone is showing full signal but the phone is actually not receiving any signal. So calls will not come in at all.

View 5 Replies View RelatedWhat do these Icons represent or mean, and the meaning when they change Colors from White to Blue (Status Icons). There was a GB 2.3.4 User Manual Posted on Moto's site, Unfortunately no information was included about these Items. What does it mean when all three are blue, Including the H+ icon having arrows beneath it at the same time? Is it also Possible to have the Intro Video Posted or embedded to this thread as well please.

I have found that there seems to be no correlation between the signal strength (in dBm / asu) in Settings -> About phone -> Status and the signal bars that are shown. Often the signal bars will shoot from 1 to 5 or 6 even with really low signal ( ~97 to > 100 dBm) that doesn't fluctuate.

I have TomTom UK running on my iPhone 4 which itself is running iOS 5.1.1.I have been having problems with the TomTom App keeping its signal locked in all weather conditons and even thinking I am on tottally different roads even when it was has a signal to start with.I then get the Poor GPS signal and can pretty much drive to work in 45 mins somedays without any signal lock and navigation.I know my route but use its HD traffic service to miss delays etc.I've deleted the software from the iPhone and redownloaded it and this hasn't solved the problem at all.

I updated my iphone4 to iOS 7.1.2 and after that, my phone started to lost the signal... from 4 bars to 3, 2 and nothing... I alredy tried to turn it on and off, i also tried to remove the sim card. and lastly, i tried to restore it to factory setting but it says that "there was an error".

Does anyone who has an iPhone 4 under an O2 contract experience a range of 1-3 bars for the signal on a consistent basis? I just got my iPhone and have been left pretty disappointed - I know having a strong/bad signal doesn't directly affect the quality of a call under 3G, but when accessing the internet via the network, a low number of bars being displayed is having a detrimental effect on the bandwidth cap, hence limiting my access to faster data speeds.
Could the last update on the signal bar display be the source of all this? I fear that this more 'accurate' determination is actually working against me. O2 is supposed to have the best coverage in my area for 3G, but even when I went to London, I seldom got a full 5 bar signal. I've spoken to a representative and they said it's very normal for fluctuations to happen, but I severely doubt this.
I've spent the past week poring over posts on here and on different sites, trying to educate myself as best I can so i can fix this issue. After hours and hours of banging my head against the wall, I can't figure anything out. My story goes:
- 2009 iPhone 3G updated to latest firmware/bootloader/baseband (3.1.3, 5.11.07, 5.09)
-Tried to jailbreak with pwnage tool 3.15 and accidentally checked "Activate iPhone"
-When restoring the custom pwnage firmware from iTunes, got a 16xx error
-Unplugged and tried to restore to original ipsw which i had backed up before
-This process looked like it went normal, but when it was finished the iPhone restarted into emergency call mode and iTunes gave the error The SIM card insterted in this iPhone does not appear to be supported (even though it is a functional ATT SIM tested and working in other ATT phones)
-I tried doing pwnage fresh without the activate iphone checked and it went through all the steps, this time without the error, but when it reset, it was still in emergency call mode.
Since then i tried numerous things to get it back to working status including, calling ATT, Apple, getting a new SIM, various Jailbreaks (Blackra1n, Spirit, redsn0w, pwnage), unlocks. Nothing worked -------> EXCEPT: When I run redsn0w, it goes through the JB, restarts and functions 100% normally, but THERE IS NO SIGNAL. I tried installing ultrasn0w through cydia, and all that does is change the signal from no bars "_ _ _ _ _" to "Searching".
So basically what I'm left with at this point is an oversized iPod touch. An iPhone that doesn't get signal. UGH.
For what it's worth, there are iPhone's without the dreaded antenna issue. I just exchanged mine at my local apple store and the new one is perfect. No matter what I do I can't get the signal to drop, even holding it tightly with two hands. The first one I had drop constantly. All I had to do was put one finger over the left side antenna and within seconds it would drop to searching.

Well I'm on the latest beta of 4.1 (8b5097d) on IPhone 4 and it does have feild test (maby it's just because I restored from my 3GS but idk). So go to your phone app and then to the keypad. Then type *3001#12345#* and press call, this will put u in field test app. At the top I can tap the bars and it will switch to db's and if tapped again it will go back. So once u tap to change to db's hold the sleep button till slide to power pops up then let go of the sleep button and hold the home button (this is a respiring). Once u do that u can just easily tap the bars or db's and switch where ever you are in your phone. Good luck hope it works on all your phones. And ps you don't need to be jailbroken!

I have just started experiencing problems with the signal quality of my iPhone 4s.When the 3G is turned on I have no signal at all (NONE!!). However, when I turn the 3G off I have a cellular network capable of sending/recieving call & texts but pretty much useless for everything else. No amount of hard resets/network resets or airplane mode switching resolves the issue.p.s I have just recently upgraded the OS to 5.1.

I am going to need an alarm clock, but the place I am going to be will most likely have no cell signal. will the alarm clock still work if I put it in airplane mode? I will be charging it at night so it won't run out of battery and turning it off during the day

My iPhone 4 keeps dropping signal every few seconds, then regaining it, then losing it again. I have to restore my phone to its factory setting which seems to work, but this is the second time is happened in as many months.

I have unlocked not jailbroken IPhone 4. It is currently running IOs 5.1 on baseband 04.12.01. Two days ago i went and got myself a new vodafone UK sim card from the shop. (i got the phone from friend of mine who got it form Vodafone UK shop Pay as You go) I put the sim in the phone, the carrier on the top came: Vodafone Uk but i don't have any signal bars. Also the 3G on the phone is working normaly but i dont have any signal, i cant call anyone on text anyone its just the 3G working properly. I went different playces to see is the problem only where i lived, i went to the next town and the next one.....NO CHANGE. I restored the IPhone because i thought that is some bug with the phone and maybe this will clear it and help me...NO LUCK.

I have a I phone 4s, recently upgraded from a 4. The I phone 4 would always switch to edge in my living room when the 3g signal was low however my 4s just seems to stay at 1 bar and say "searching" when 3g signal has gone whearas my 4 would go straight to edge. I have only ever seen my 4s switch to edge once and when it does I get 4 bars! at home its ok as I can switch the wifi on however when I am at work etc and take the phone out of my pocket its almost always "searching"? just wondering if this is common for a 4s not to use edge or is there something wrong with my phone?
View 2 Replies View RelatedI've had an iPhone 3GS on Orange since April 2010, and am waiting to upgrade until the 5 (or whatever they call it) comes out later this year. I've always had a full 3G signal in my house since I have had my iPhone. Around 3 weeks ago, I suddenly noticed one evening that I had no signal, I put it down to a local reception problem or something and ignored it. Later that evening though, I realised that my wife, who has a Blackberry Curve also on Orange, still had a full signal. I also have an iPad 2 3G on Orange, which had full signal still, and then my brother came round with his iPhone 4 on Orange and again had full signal.
The next day I was driving to work and suddenly my signal reappeared, pinging in half a dozen texts and missed call alerts etc. Then when I arrived at work (where I usually get 2-3 bars of signal) again my phone showed No Signal. One of my colleagues has an iPhone 4 on Orange, and sitting on the table right next to my phone was getting 3 bars of 3g signal, where I had nothing. Walking around the town on my lunch break I managed to get 1 bar up and get a text in.
Over the last few weeks this pattern has repeated. I can still go to some places where I can get a full 3g signal. Sometimes I'm driving and the signal comes in for a while then goes. Sometimes I go to larger towns and get a full signal easily. However mostly for the last 3 weeks I'm getting no signal. When at home, if I go out of my house.
I have tried a normal restore, a reset and a DFU reset. Funnily enough these all seem to make it suddenly work again at home for about half an hour, then it disappears again. I've read about some people having a problem with jailbroken phones, but this phone never has been. I'm guessing there could be something wrong with the internal ariel, but it puzzles me why it still sometimes picks up a signal. Is there a signal amplifier in the phone that could have gone wrong and it's making it harder to find the signal?
