Just now downloaded iOS 6. Took almost 2 hours, but then internet here is crap anyway. Was actually lucky I had a consistent connection while it loaded.


Anyway, I haven't had much chance to test the "call failed" problem yet, but I did notice when I checked the "Show My Caller ID" part, it was 'OFF'. After I switched it to 'ON', and checked again a few minutes later, it showed 'OFF' again, ***! I did this several times, same results.


Also, after downloading and updating the iOS and many apps, I did a 'reset network settings', then checked the 'show caller ID' and it was off, turned it back on, checked a few minutes later, it was off again!


I'll give it some time to see how things go the next few days, but I ain't holding my breath - again! Will note any changes, improvements, or lack thereof here as I find them.


Edit: Should probably mention (if I didn't already somewhere in this discussion) that I've got a white iPhone 4s, 64 GB, factory unlocked for GSM, and using it in Thailand with GSM sim card.

No body wants to know the solution I posted this a while back.


I had all the issues with my iPhone 4S I narrowed it down to the modem if 3G was disabled it worked if it was enabled the issue was intermittent.


I spoke to a genius and explained everything I did I even tried putting my sim into a different 4S that I knew worked and there was never any issues. I came to the conclusion that it was a fault with the modem inside the phone the fella agreed with me.


So I swapped my phone and it worked no more issues


The only solution existing is a new phone as I said in an old post on this discussion it's like taking a lucky dip you may have to try a few times and I know it's annoying but I only replaced my phone once and never had any issues since.


You will get call fails from time to time if your in a poor area or if the other person your contacting is in a bad area. I've had about 2 maybe 3 call fails since I replaced my phone (which was about 3-4 months ago) but I know my house has a poor signal and I know the person I contacted lives in an area with poor signal. If am out or I phone someone in a good area I have no problems. I'm living proof that replacing your phone fixes the issue.


P.s. using my phone to type this so CBA fixing typos or grammar.

I've had my black iphone 4s 16 gb for 8-9 months now & i never had the issue of failed calls or any of the above mentioned problems till now .
I recently upgraded to ios6 & ever since that update I get a "Call failed" message evry time i call someone !
What do i conclude of this?........ios6 The CULPRIT ?
I tried resetting the network & phone but nothing works !

Hmm... interesting. Because with the problems I've had all along I was hoping iOS 6 would resolve them, and it didn't. And therefore I concluded that it has to be a defect in the phone itself. But now that you say you've had no problems until you loaded iOS 6, it makes me wonder again.


Since my last post, I've had a chance to further test phone calls and I'm still getting "call failed" messages with almost every call. That's with the 4s 64 GB, factory unlocked for GSM, iOS 5.1 and since upgraded to iOS 6. Same problems, no difference.


Biggest deal to me in all of this is that Apple continues to ignore, or at the very least refuses to acknowledge there is a problem and/or address the problem. And with recent problems I've had with the iPhoto update for my MBP, and sketchy reviews on OS Mountain Lion, a rather unspectacular iOS 6 (IMO), and other issues, I'm beginning to lose faith in Apple's commitment to produce top-notch, customer-first oriented products.


Has Apple grown too big for their britches? Is it time to go back to (the now little guy) Windows?? 😮

I had a 3GS until last week when I got a new iphone 4 with ios 6. Since then I have most of my calls dropped, normally after less than a minute, sometimes the other persons voice sort of sticks, like a stuck record and I have to end the call. This is very frustrating - had no problems like this with my 3GS. Looking as this forum it's not looking good to get a fix which is depressing. Maybe I should cut my losses, sell it quick and get a Galaxy

You know , When u sit n think of it , it really ***** !
We now have a phone which doesnt let u make any calls !....How bad can a phone get ?....It doesnt serve its purpose !

Im just sitting here n hoping , that i will find a solution someday !....i guess its time for a software update from apple that fixes the problem , probably an ios 6.1 ?

So, I just started having this problem. And then I put my bumper case back on. Apparently, some of these issues are caused by receiver/transmitter interference. The bumper acts as a ground. Having it in your hand diffuses the signal. Tried all of the turn-this, turn-that off stuff. Reset my settings. Nothing worked. Put my case back on and reception ensued. Twenty buck fix.

I updated to the latest OS early last week and things were fine. 2 nights ago I experienced a drop call and have not been able to have a successful call since then. Most of the time it's not successful in connecting, and if it does it drops. Battery life has been draining too at an alarmingly fast rate since I've started to experience these problems. Any software patches coming our way so I can use my phone again??

Oct 16, 2012 8:54 PM in response to DaraB224

DaraB224, I had the battery drain problem myself for awhile. I found it was caused by the phone losing the cell signal, then constantly having to re-search for the signal.


If I was able to catch it ("no signal") in time, I would put the phone in 'Airplane' mode for a few seconds then switch it back again. That would usually clear the problem, and my signal would return. If that didn't help, I would shut down then re-start the phone, and that helped. But then you just never know when the phone will lose that signal. So you may pick up your phone after a few hours and find that your battery is drained!


We've been around the horn with this on this forum for some time. I have written to Apple detailing my problems. I am convinced they are aware of it - and just don't care. I am totally disgusted with their lack of concern and failure to acknowledge the problem. I will be looking elsewhere for my next phone...

Yeah there's definitely something screwy about that 'Show Caller ID' thing. I've noticed it in the past, but can't put my finger on what it is or how exactly it affects anything. Sometimes it shows it's on, sometimes shows it's off. When I turn it on, I'll check it later and it's off again. Doesn't seem to be any consistancy - one way or another - in how or when or why it does whatever it does.


You say you've got the iPhone 5 and you're having these problems?? That's something new, at least as far as this thread is concerned. In fact that throws a whole new monkey wrench into the works here, as I assumed everyone here was having their problems with the 4 or 4s phones (mine is a 4s).


Somehow, and I may just be wishfully thinking here, that would seem to indicate that it is indeed a software problem, and possibly fixable (in the future). Which would suit me far better than knowing my phone is an $800 paperweight. But as I say, I ain't holding my breath...


I'd be interested to hear any developments (or lack thereof) with your problem with the iP 5... Keep us posted here if you would please!

Oct 18, 2012 11:00 AM in response to DaraB224

Actually DaraB, I never liked Samsung's stuff. Not sure why but there's just something about them I never liked.


To be honest, if this iPhone thing doesn't get taken care of, I'm gonna buy the cheapest-@ss phone I can find, for like ฿1,000 ($30), just for phone calls, and just use my worthless iPhone for a paperweight and occasional iPod.


Or maybe I'll just let all my frustrations out and heave the piece of junk into the Andaman Sea for ha-ha's and let some shark or sea turtle deal with it!
