IPhone :: Loosing Cellular Data And Internet Connectivity With 3-4 Bars Of Signal?
Jun 12, 2012
I am having an awful time loosing cellular data - can't send or receive text messages, use Safari or Find my Friends etc. I came into the forums looking for help and found posts about the personal hotspot constantly spinning. I looked at mine and it was too. I did a hard reset and it finally stopped. Immediately I got connectivity back. I don't know if that is causing my loosing internet or not but it seems coincidence that when it stopped spinning I got it back.Simply going into and out of airplane mode and toggling cellular data on and off never restores connectivity. Often it will restore when I leave the building. But I have 3-4 bars of signal and 4G listed as available when I'm inside.Also, something is chewing up my battery. I was at 100% when I left the house at 8 am and at 65% at 10 am with the phone sitting on the desk doing nothing.

Ever since I upgraded to iOS4.0, my iphone 3GS has been losing its internet connection over 3G.The 3G indicator remains lit on the display, however when trying to surf or use an app that requires internet, it simply times out. In order to get my internet back I need to reboot the phone, or switch airplane mode on, then off.It seems to occur after I leave the house, so it may be that the phone is having trouble automatically switching from Wifi to 3G.Does anyone have any suggestions on how to fix the issue?

i have not been able to get a data connection all day. i lost my data connection near my house this morning right on the border of 4g/3g area. i drove to work about 25 miles away where there is 3g only and still have not been able to establish a data connection. i have rebooted the phone, pulled the battery, rebooted in safe mode, switched to cdma only, switched on an off airplane mode countless times and still have no data connection. i do have a 3g icon with almost 4 bars in the status bar, but no connection. browser not connecting, no facebook, no Internet...nothing.

I have tried this on 3 different Nokia E6 phones, on GPRS with 5bars, 3G with 5bars and at home over wifi. All internet traffic is really slow, when on the browser downloading the SIS file for google maps, it took 5mins to download just 160k. Once I did get it installed, the Google Maps app take ages to load map tiles, and emails take about a minute to download an email with just a few lines of text.
When using OVI store, pages load really slow. So all internet apps are slow. The phone overall is quick. All this in an edge or 3G area with 5bars, and 3 phones do the exact same. All firmware ver 22.14. Same settings, area and sim card in my Nokia E71 and E72 are perfect.

Last night when I turned on my wifi at home, the wifi and phone signal bars appeared but were gray and I had no internet/data connection. I checked the wifi settings which indicated I was connected with good to excellent signal. Toggled the Wifi on and off several times, and turned phone on and off, which did not work. Went into wifi settings and told it to forget settings and reconnected, same result. When I turn off wifi, 3G appears and data connection is restored. Left the phone on in the media dock all night, and this morning when I turned on wifi, all was fine. What does gray signal bar mean?

I need help getting cell tower reception on my phone. Using China Unicom as Network Carrier. I am located in Guangzhou China (a major metropolis). The problem is not with the SIM Card itself because it has been tested and placed in other phones & it works well. Reception Bars fluctuate between 0-2 bars at most, both in and outdoors.Have noticed these problems since upgrading the phone to IOS 5.0 & now also on 5.1.1. No problem with Wi-Fi Networks. I have also tried Resetting the Network & taking out the SIM Card and putting it back in, but this has not helped.

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 am using Nexus5 (Android 5.1). Actually, my network provider has charged me for cellular data usage which I never did. In-fact, I haven't subscribed to any data pack and was charged heavily. I always use internet through WiFi.
My data usage widget is displaying 0B data usage, but my network operator is insisting that the data has been used by the device.
I want to understand if this issue is really due to my device.I see different cellular network icons on my device :-
- Exclamation mark in cellular network when WiFi is disabled (I never enable cellular data)
- R sign in cellular network (cellular data is disabled and i am not in roaming)
- No R or exclamation sign (both WiFi and cellular usage is disabled)
I am not able to understand,Is my cellular data usage is really due to my device settings or is due to some issue by service provider.
Is it that the device is indeed using cellular data despite of the fact that cellular data option is disabled and it never shows this usage in data usage widget.
I observed that when I use Wi-Fi, then exclamation sign from cellular network is removed, does that mean that the cellular data is also used and that's why my service provider has charged me?

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!

I received my iPhone 4 on launch day via a pre-order. I am very grateful to have it and to have received it while others still try to get one. Anyway, onto the issue. I had signal drop issues from the get go, occasionally even a few dropped calls. Per Apple's statement and other blog recommendations I bought a case to alleviate the issue. It's the Griffin Reveal. It is a nice case too. Last night I noticed low signal bars after a dropped call and realized I was holding it over the left corner. I let go and up went the bars.
I called care. They opened a case # and gave me the same as anyone else. I was told that I needed a bumper to fix the issue, that they couldn't guarentee with any third party case it would fix the issue. I responded asking why I should give another $30 to fix an issue they know about. I asked if I would recieve and email or call to follow up and they said they didn't know. I will follow up in 2 days and let you know. Is this a ploy to just get people to spend more money? 1.7 million sold in three days x $30 for a bumper = $51 million more for.

I have been searching for a way to remove or hide signal bars in ios4. I will often have very low bars and keep looking & thinking about it. But most of the time my IPhone 4 works as I need it to. I would like to remove or hide the bars, out of sight out of mind.

On my 3GS the signal bars are sporadically cycling down to one bar, then searching, then no service, then back to full 3G bars. All this happens in about the time span of 10 seconds or so. Anyone else have this issue on a 3GS that's jailbreak / unlocked! I've removed the blackrain app off the phone, winterboard and the issue continues to persist.

Some times my phone stops making and recieving calls. It looks like it is working, shows it has signal on the bars, for a while, then they disappear.I have tried hard and soft resets and restoring the phone. Usually if I leave the phone over night it starts working again in the morning so I figured it might have been a carrier issue. I am using GiffGaff but the phone was purchased directly from Apple and is factory unlocked. When this happens, if I make a call it looks like it is about to start making the call, but never changes; If you his the end call button it says Ending call... but freezes like this until you restart the phone or kill the phone app. I have tried my sim in my wifes phone and it works fine, I am unable to try anyone elses as they don't wish me to butcher their sims My phone acted exactly like this once when GiffGaff had issues one weekend, once they sorted their issues it has worked fine since.
I am a good 70 miles or so from a Genius bar and never really wanted to send the phone away in the post, as likely it'd take over a week to get it back, how ever, as my phones no longer functioning as a phone, I guess it isn't much of an issue any more If I could fix this myself I think it'd be great but I have started to get the feeling maybe it is some hardware issue with the phone.

I have been experiencing too many call failures lately. It seems that I have enough bars. If I do a hard reset, the phone acts better for a short time, then the call failures come back. I have ATT.

iPhone keeps going from 3G to Edge and then showing no bars. And after I turn off cellular data and put it back on to get back 3G it loses all bars completely and goes to "searching.." and then finally "no network"Â and then I have to manual search for my network. Whole problem starts happening all over after connecting again.
I have an iPhone 5 with latest OS 7.1.2

My battery icon from time to time moves to the left. I've done some search but couldn't find if anyone else is having a similar issue. I'm on 4.0 iphone 4 stock. Jailbroken, Unlocked. I'm not sure if I remember this occurrence before the jailbreak.

I have the Nokia E71 On O2.
When i hang around with my mates, the have normal Samsung Or LG phones and they get lets say 4 bars of signal on O2.
I will be standing with them and i get nothing. I feel like my nokia phone is just rubbish on this part.
Or would there be some setting i need to change for it to work? - Or is the phone faulty?

I purchased an unlocked Sony Xperia Z3 yesterday. I placed my sim in it but the phone keeps saying that there is no service and there is currently no bars. When I try to call it says I am in flight mode even though it is off. I had a friend who had this problem but it fixed itself.

yesterday morning my Sony z3 was working great when all of a sudden the signal dropped and said no service. It has been 24 hours now and still nothing. I restarted the phone many times, did a factory reset, updated software, fixed software and left it off for a while.
