IPhone :: Unable To Get A Signal Bar?
May 5, 2012
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 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 frequently lose signal in my work place because of bad coverage. When this happens, my phone is unable to retrieve any signal until I reboot it.Â
I have tried activating and de-activating Airplane Mode to get the phone searching for a signal again, but this no longer works.Â

I have a iPhone 4 that signed up to Sprint, and I've had this for 5 months and nothing happened. Now my iPhone is not sending text messages or sending calls. Even when my Sprint signal is high, it doesn't seem for the text messages to go through or heck not even the calling. Only when my iPhone is in Extended "Roaming" it could send texts and calls. Is there any suggestions into solving this issue? Or do I need to replace this iPhone? I tried turning it off and on (didn't work), and Restoring the iPhone (still didn't work).

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?

Info from ABOUT DEVICE:
Blackberry Torch 9800 Smartphone (3G, Wi-fi)
6.0 Bundle 695 (6v.0.0.246, Platform 6.4.0105)
3G bands 1,2,5,6
Phone is on 3 network
2G Signal not working.I have had my BB Torch Since November last year, I have been working away from home alot and never had any problems with signal. It has always been on 3G set up on my phone.Due to a new little family member i have had time off from my work and been staying with my family, I have noticed that the signal in my house on 3G is not great. I switched it over to 2G on my handset and noticed it gets NO SIGNAL at all. I went out side and still the same no signal on 2G but soon as i change it over to 3G its fine.In the past i have had the Bold 9000 and it was set up on 2G & 3G so it would change over to which is stronger.I got my old bold out and have tried my sim in it and it works on 2G with no problems.Is there a fault in the torch with 2G signals?

I have this model phone which has been working very well until today.It started by not sending a text message, and then seemed to go out of signal.I have tried everything normal - resetting, testing phone out with another sim etc.It appears that the sim is the problem as it will not work in another handset, and is displaying no signal there.In the W380i, there is a strange symbol, a telephone with a red line through it, which I cannot trace anywhere in the user manual or online.Does anyone know what this indicates? - ie is it a network fault, or something wrong with the sim?

I want to report a bug after the last update on Lumia 800.
Product code: 059M3C1
Carrier: TIM SW variant ID232 v.06
OS Version: 7.10.8773.98
Firmware revision number: 1750.0805.8773.12220
The phone is unable to get any 3G signal anymore (Tested on the following cities: Bucharest, Constanta, Timisoara, in Romania, the cities are like 300/500km distance between each other), I get the "H" symbol (before I had 3G), also "Internet Sharing" is not working at all, even though I can connect to the Internet via Cellular. I've tested with and without WiFi signal, the error I get is: "Connection not shared" - There's no cellular data connection to share right now. Check your cellular settings and signal, and try again.I have 4 bars out of 5 signal, and active internet connection.

What 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've had this twice now where I couldn't get a GPS signal. This never happened on my Droid 1, but has happened twice in less than 30 days (two different phones - since I replaced the first one when this happened). This has been in 2 completely different locations.

I was wondering if anyone knows what algorithm is used for the signal bars on the Photon 4G. 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.

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 have found a way to easily switch your signal bars on your status bar from regular bars to db's and back whenever you want. 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!
