Dropped calls with full signal

When I am on my iPhone with a full or close to full signal, the sound cuts out for a while and then come backs a few times, and eventually drops the call. Its not every now and then...it's every call!
I have synced and restored it...and neither helped.

This does sound more like a faulty antenna than a SIM card problem to me. It may be that when the iPhone switches towers, as it does periodically, even when on full or near full signal strength, there is a time lag between disconnecting the previous tower and locking on to the new tower. This used to be a problem with old analogue mobiles that employed "hard" handoffs rather than "soft" handoffs, where the new tower is locked on to before disconnecting from the previous tower. In any event, with digital phones that still use hard handoffs, the technique has been refined to the point where the change is said to be imperceptible (does anyone know whether the iPhone employs hard or soft handoffs?).
Try replacing the handset and see if that improves matters for you.

Excessive dropped calls with full signal!!!

I have a 3GS and have updated to 3.1.2 I recall that one of the items addressed in this update was the dropped calls issue. Mine have been severely worse since the update. It is quite aggravating when the calls dropped are when I have full signal. I am not the only one I know with this particular issue. Is this being addressed?

The phone on the iphone is not the best. I live in Dallas and when the phone is on 3g it really is unusable. Just for grins I started a call log for a day. In my very unscientific experiment I dropped (or couldn't hear the person and had to call back) 76.6% of my calls when I 3g for the day. In my opinion, Apple or no Apple, this is unacceptable for any cell phone. I tried calling ATT to see if I could get some credit and they said no. I have taken the phone to the apple store and they said it was the network not the phone. I have restored the phone, reset the phone, updated the phone, and still nothing seems to work.
However, when the phone is in 2g it seems to work fine. Except the only problem with that is when you are searching the net, or checking email and someone calls you it won't ring. This a mild annoyance because at least when I do call or someone calls me I can talk to them and they can hear me.
The iphone is the worst cell phone on the market and best pocket computer you can buy.
You decide.

Weird: Can't Make or Receive Calls with Full Signals

Got an unusual one for you. For the most part, my iPhone has been excellent. Just about anywhere I go (in NY Metro area) I have had no problem making and receiving calls. The one major problem I have is that it does not seem to work at my desk at work. The wierd part is that I have FULL Antenna Signal and FULL EDGE signal at my desk (3rd floor of a 7 flr bldg) yet calls can not be sent or received. Incoming calls can not even be sent to voicemail, they are simply not connected at all (just two beeps after dialing). However, I do have internet access(although limited) and no text messaging ability. If I walk around the floor of the building and go closer to a window, the calls can go through, texting works and the internet is blazing. I called Apple who routed me to AT&T. ATT was so wrapped up in indicating that they do not guarantee reception indoors that I don't know if they really even considered whether it was a service issue or an iPhone issue. Either way the rep said that they have been dealing with this issue where full reception is identified but there is no service. They also indicated that the issue is predominantly found in large buildings. Any ideas on how to solve this??? Oh yeah, the guy in my office 8 ft away has Verizon with no phone calling problems at all. Thx 4 the help.

I went through the same with Verizon at my house. I had been a Verizon subscriber for my personal cell phone since the summer of 2001 until 3-4 months prior to the iPhone being released. While a close friend of mine was visiting for a few days who is an AT&T subscriber, he had much better reception at my house - not 5 bars but much better than the 1 bar I had with Verizon. I contacted Verizon technical support who told me the very same - they are not responsible for reception inside any building - too many factors with building materials, etc. Verizon updated the software on my phone, replaced the battery, sent someone out to my house and neighborhood to check reception, gave me another phone to use as a test but at the end of the day, nothing changed so Verizon let me out of my contract with a year remaining without charging me the early contract termination fee. I use my personal cell phone in place of a landline so reception at my house is important. I have much better reception with AT&T at my house - both with my first subsidized phone and with my iPhone.
Somewhat different from your situation with having full reception but not being able to make calls but since this only occurs at your desk at work, I don't believe the problem lies with your iPhone. There is probably a Verizon subscriber that may have the same problem at another location in your building. There are differences between CDMA and GSM networks which probably has a factor in this. This is relative by provider depending on location. There are some areas that I frequent often where I have reception with my iPhone but I didn't with Verizon.

Will not call or receive calls with full signal!

This is my second iPhone 3G (I got this one a month ago) and I am unable to make or receive calls. If I dial a number, the other person's phone rings once, then my iPhone says "Call Failed." Also, when receive, I touch Answer and the iPhone freezes. The signal bars and the internet "E" disappear when calling too. Texting (SMS) and the App Store work perfectly. I just tried to enter the serial number to connect with an Apple expert and "We're sorry, but that is not a valid serial number. Please try again." appeared. Is there anything I can do besides sending it in to fix this?

Hi,
Try restarting the iPhone by holding the Sleep/Wake button until the red slider appears> then slide to turn off> and turn the iPhone back on by pressing the Sleep/Wake again, as described on page 34 of the iPhone User Guide.

TS1398 my problem is my iphone 4s is connected to the internet(wi-fi) with full signal strength but freezes when browsing and says "Cannot Open Page, Safari could not open page because the server stopped responding".

my problem is my iphone 4s is connected to wi-fi with full signal(3 bars) strength but freezes when browsing and says
"Cannot Open Page"
"Safari could not open page because the server stopped responding"
I already reset the iphone to its factory settings and erase all contents but still the browsing speed freezes or not searching at all. Sometimes it will work and fast but then the problem uccors every now and then. Iv'e been using iphone 4 for two years and I still have it and works fine compared to this IPHONE 4S.

Settings → scroll down to Safari → in Safari settings, I selected both Clear History and Clear Cookies and Data.
IF that does not work -
Restart or reset your iPhone, iPad, or iPod touch - Apple Support
Finally - if problem still present -
Go to Settings>General>Reset
Reset the network settings - you will need to add the password of your home WiFi in your phone once more
The device should turn itself off & back on then go into Settings>Wifi and join your network

Dope calls with great signal, how do I get a free bumper?

I know about the "holding it" wrong problem but this isn't it. I get a lot of drop calls, I never did with the 3G. I have signal bars, thats the issues. Anyone have this problem? also I seem to but people on mute at times when I am talking. How do you fix this? If not mute it will jump over to the keypad.
Also I did a search but can't found out how one gets the free bumper case that Apple said they would give out. thanks

Might want to try searching the forums, as this same question has been asked and answered umpteen times.
Apple will be posting info on the free bumpers on their website sometime this week. Keep checking.

UK 02 - often unable to connect to site even with full signal

Sometimes my iPhone will refuse to connect to web sites or the email server, even though I have a full signal and gprs with or without edge. It's been doing this frequently since the latest firmware update and it's getting a bit annoying. It doesn't seem to matter where I am located.

I don't have an answer. However, since your question is not about Acrobat forms, but Designer forms, you need to ask in the LiveCycle forum that deals with Desginer forms.

Ringback tone issue on outbound call with full E.164 number between 2 sites

Hi there.
We have been encounting issue where site A calling site B with full E.164 number users expereiencing no ringback tone on caller while phone is ringing on site B.
In CUCM, Route Pattern is configured to use TEHO for long distance call. For instance, if site A dial site B with full number with area code, call should be sending out via site B VG.
It was working fine until recently, there is no change made on VG nor in CUCM.
I have attached dial-peer config of site B, should i add below subcommand under all dial-peer # pots?
progress_ind alert enable 8
progress_ind progress enable 8
progress_ind connect enable 8
//Site B dial-peer config //
dial-peer voice 1 pots

Yes I have expereinced this too..Even when you call an external number and the user rejects the call, you hear a normal ringback tone over sip trunks..I think the issue is that the ITSP sends a 183 session progress or 180 ringing even before knowing what the state of the called device is..
You can send us a debug ccsip messages for a test call and we will be able to know exactly what is going on

I'm dropping calls with perfect service..?

I have all my bars so I know I have perfect service but yet my calls are dropping 30 seconds in. I can't even talk customer service because I can't stay connected that long. Has anyone else heard of this? I have service so I am really confused.

I never had a trouble with calls ending or dropping until I upgraded the OS last week. Now, I have actually watched my phone and during a call with great connection, the call just ends like I hit the end button. Today alone I watche dmy phone drop three calls. I don't think this is a SIM card issues but a software issue form the update. The other problem is for no reason at all, my music will start playing. I have the phone sitting on the table (no movement, nothing bumped it) and the music just starts playing. I have even had calls drop and music starts playing.

Dropped calls with apple usb modem

The USB modem drops calls frequently. My ISP is earthlink which told me to reX duce the stated modem type to V50 or lower as a fix. But that has no effect.
I have bootcamp and windows Xp Pro Service pack 2 installed along with office.
But use the modem only with Mac OSX10.4.7. it is really frustrating.

Hello,
I have had this problem. My 1st MacBook, wk 30, could not maintain an internet connection via external modem. A primary function. I was a novice with OS X. I rewired my household phone lines, verified my external phone line, dogged my ISP and spent hours with Apple Tech Support applying numerous, ineffectual, suggestions.
That machine was classified as DOA, eventually, after a number of panics, corruptions, and other bad behaviors related to power management. I lost the indexing for hundreds of emails saved on a crucial flash drive - a USB function.
My current machine, wk 33, demonstrated the same frustrating behaviors upon receipt. !!!
I am methodical. I calibrated the battery and performed system updates 1st thing with both machines. Then I became proficient with clean system 10.4.6 reinstall and worked my way backwards.
In my case, the 10.4.7. system upgrade caused the USB modem malfunction to recur. Subsequently, plugging the modem into the right had port enables it to function.
I am now unwilling to plug any other device into the left hand USB port and am limping along.
The last word I had from Tier 2 Tech Support was that there are no known issues.
Cordially,
RLC

Nokia N8 Wi FI Connected With full signal but no i...

Hello
I am having some issues with my wi fi at home. I just bought the phone a few days ago and it worked fine for about a day. I can connect to my router with no issues but it wont connect to the internet. Its saying it has full signal from my router and that its connected but i'm unable to connect to anything internet related. My Xbox works fine with the router and so does my G/fs Htc Desire so its not problem with my modem or router. Ive deleted data and restored a couple times as well as disabled the power saving mode in Wi fi settings. It is hooked up using a WEP key with mixed 802.11n, 802.11g, 802.11b. I've changed the wireless channel 1- 11. Hoping to get some feedback so i dont have to send it away.
Much Appreciated
Matt

Turn from 802.11n to 802.11b/g. Use a WPA/WPA2 shared key.

Reception & Dropped Calls with 4.0.2

I upgraded to 4.0.2 a couple of days ago and since then I have dropped 7 calls. In the entire month and a half leading up to this I dropped 2 and 1 of those was my fault (covered up the lower left corner before I knew better). I spoke with my wife and a couple of friends and every one of them has also noticed this problem. Now I want to know if everyone else has noticed this or is it just a local thing (Jenison/Grand Rapids MI area).
As a side note my batter drains a heck of a lot faster since I upgraded as well.

I have had a similar issue with respect to dropped calls. I'll be talking and then I realize that it's eerily quiet on the other end and pretty shortly thereafter the call will drop. My iPhone4 is my primary phone for work so this has been a huge problem this week. Prior to the 4.0.2 upgrade, the phone work pretty much flawlessly with very few dropped calls here in NYC. This week I feel like throwing it out the window more often than not.
I went to my local AT&T store to see if that was an issue in my area or with my specific device and he told me that my best bet was to do a reset on the phone (hold down home + top button past the shut down screen until the phone restarts) and wait for 4.0.3 software, which he claimed would be out in the next 2 weeks. He said I'd likely have to do that hard reset at least once a day to keep the dropped calls to a minimum. I did the hard reset and had a couple of calls, which were mostly conducted without issue. Once I did get cut off but it's hard to say if that was my phone or the far end party because they were talking on a Bluetooth headset while driving.
Tomorrow once work starts I'm going to try out running on EDGE to see if that solves the issue as well.
Apple has been annoyingly tight-lipped about this one because it's pretty clearly a 4.0.2 issue. Oh well. Hopefully these temporary fixes can hold me over until 4.0.3 or whatever the next update happens to be. Hopefully this isn't treated like the alarm clock bug that's existed since 1.0 (i.e., ignored).

Why does my iPhone 4S drop calls with good service

Why when I have 3 or more bars does my iPhone 3S drop calls?

Go to Settings > General > Accessability > Incoming Calls then set to default.

Phone call becomes garbled to other person after about a minute into call, but I can hear them clearly. I stood by a tower with full signal and was still hung up on because I couldn't be heard after about a minute. Please help.

This is a recent occurrence. I either initiate or receive calls, and about a minute into them, the person cannot hear me because it becomes so garbled to them, but I can hear them clearly. I was able to make one call that was completely clear, and that was tonight, but it was one only. I've done a master reset, but I have not deleted all data, as I'm afraid to do so and lose pictures. The only other option I supposedly have is to replace the phone. Please help. What could this be?
