IPHONE 4s call failed??!!!

FWIW- I posted a month or so ago on this thread- all the same issues 🙂. I finally got in to Apple about a week or so ago and got my phone replaced. Same SIM, nothing else new except the phone (even restored from iCloud backup). Haven't had the issue since.

Hi Alex

When you received your new phone, how was it packaged?

I have received two replacement phones, switched sims etc but the phones all have the same problem and came in a slim black Apple box rather than the normal iphone box.

Thanks in advance

Hi guys

I just want to share my experience regarding this matter. 10 days ago I bought a new factory unlocked iphone 4s from an electronics store in my country Jordan. So the next day while I was using the phone I noticed that many calls did not get through and I got the "call failed" error around 30% of the time. We have another iphone 4 at home so I decided to switch sims and try to test, I put them next to each other, and still I got same error on my new iphone, and in the morning when I woke up, it said "no service" and I had to switch it off and on again before it worked. So finally, I decided to take it back to the store, the guy at the store said that this is a settings issue, he changed a couple of stuff added a pin code to the sim and asked me to try it, still I got the same error. The next day I went back to the store and they asked me to change the sim!! I got a new one but still I got the same error! The third day I asked for an exchange, and the guy there said that their technician needs to check it first before they can return it. I said alright and they took the iphone for 4 days!! and I went to the shop again, they said that the technician had checked it and there's nothing wrong with it!! bull! I told them look I'll take it home and test it and if the error comes up again I'll return it. I went back home and boom the error appeared again, I actually noticed that the error appears specially after the phone sleep, so if I let the phone sleep and then try to make a phone call the error would show. I went right back to the shop and asked for an exchange, at first they were reluctant but when I tested the phone in front of them they were convinced and finally replaced the phone! Now I'm using the new phone and so far I haven't faced any problems so I assume that it was a hardware issue, so my advice to you guys is to try to get a replacement as quick as possible! Hope this helps 🙂

I posted in this thread on December 1st. (Yes, restored, got a new sim card, and got 4 replacements from my Apple store - still same issue - until now.) After posting, I called and had a replacement sent to me instead of swapping out phones from the same Apple store (and the same batch of defective phones!). I have not had the same problem. It has been a 6 days since my replacement came. (I had to send them my phone and they did diagnostic testing and determined I needed a replacement.) No problems. (Knocking on wood.) So I feel pretty sure it is not a carrier issue or an iOS issue.

There are at least a few bad batches out there with a range of issues: no outgoing call audio, dropping calls like crazy, battery issues. Just replace your phones.

Hi All

In response to my last post, I've just been informed by Apple Support that a software update has just been released to fix this issue.

You have to backup your phone and then click restore in iTunes.

It will come up with iOS 5.0.1 but it's actually a newer/updated version of the last iOS update designed to address this issue and other slight i4s faults.

I'm downloading it now. I will test it out over the weekend and share my results.

Best wishes

Me too. It cannot fix with my iphone 4s. all 5.0.1 9a406 and 5.1 beta 1 and 2 are *****. Apple *****. Are they trying to make their customers insane? What the **** with the 5.0.1 update????? to fix the battery? NO... to destroy the phone network? YES

In response to my last message, I did the update. It didn't work. I've had multiple failed calls and loss of reception. I've emailed Apple Support and I'll share any useful information I get back.

iPhone 4s - white - Vodafone UK - 3rd replaced phone.

As I posted earlier, I was having the "call failed" problem (not other ones that are also discussed in this thread). Since my last posting I raised a formal ticket with Apple. They recommended that I backup the phone, reset it to factory settings, and then restore from backup. I was very sceptical about this as it didn't seem very different to what I'd already done (buy a new phone, upgrade firmware, restore from backup). However I'm pleased to say that since then (about 3 weeks) I haven't had any failed calls.

I'm having very similar issues over 50% of phone calls won't give you a ringing tone try just connect and then there's silence! Then if I switch to another number and you try to ring the speaker phone will highlight and you know it's going to do f£$k all then too. Have turned phone off and on but still get the issue. Doesn't seem to be any pattern can be the first phone call after turning on or the 5th but once it starts it's random. Could effect the next 10 'attempted' calls or miss a few. Have noticed that certain peoples contacts generally cause the issue which I've removed and re inserted in phone but again issues appear soon afterwards. (the numbers my sister to). Have been to the apple store already and was flogged off with a full apple reset but guess what it's still doing it. As I'm sure you can imagine its highly frustrating. The very basic it should do is make a phone call! My dad remarks his 8year old Phillips phone works everytime! I understand this is a most likely a software issue as it generally happened after I updated it to 5.0.1!

I have been having this problem with my iphone 4S on o2, and while it's only a temporary fix (as it undoubtedly happens again in a day or two), I do seem to be able to solve the problem by turning my phone off and on again.

However, I would really like to know what an Apple representative has to say on the matter....!

suprisingly i travelled to my home country and i was using TMobile Hungarian, i had an excellent battery life, while using tethering aswell. i got back to the UK and put my vodafone sim init and the battery got back to the "bad" state again... i think these problems are more related to the carriers not Apple.

Same problem here, my iPhone 4S 64Gb drops calls. Yesterday it cut me off in the middle of ordering the last avaliable seat on an international flight and it has been intermittendly dropping calls ever since. This is pretty annoying, I've put up with all kinds of shortcomings in the mobile phones I have had over the years. Unreliable Bluetooth in my HP iPaq, crappy e-mail client in my Nokia, a crashing music player on my Nokia, an inability to play video clips on several phones and the crappy Blackberry OS web browser... I leared to live with all of this. However, being able to make phonecalls reliably is not negotiable.

i m having the same problem since i have upgraded my 4s to 5.0.1 firmware 1.0.14 build 9a406. cant find the sollution restored it twice changed micro sim didnt work at all. my edge and siri starts working but as soon as i ask siri to call someone call failed massage arrise and signals goes down and phone start searching the network again. hope to fix it soon by someone's help

I am sick of this, it seems like every time I try to make a call it says call failed. I have also realized it's not just the callling but the entire network. It shows I have full 3G service but I can not call, recieve calls, text, or surf the internet. I live in Atlanta and am on AT&T, also I have multiple friends with the exact same problem. It is time for Apple to fix this.

It might be that your carrier is meant for data call and not voice call. I'm hooked up with data calls, so I can see 3G but not able to make voice call. That means you can browse the internet but can't make any calls. Alternatively, you can try to put the simcard on another phone and see if you can make any voice call. If it does, then the possibility is the iphone issue. If you can't make calls, then it's your service provider carrier.
