iphone 5 calls failed

I am having the same problem. I am finding that it is intermittent. I drove to the Rogers Store that I purchased it from and the phone worked well. No problem. This morning I am back to "Failed Call" again.

I also experienced this on 21-2-13 next morning and evening. I thought it might be a common problem other features. I try exchange my sim to another phone and it's work like normal phone.

It turned out in my mind is probably the troubled mobile iphone. I try to use the iphone to try, however, remains the same failure. I don't care because i still can using sms and whatsApp.

on 25-2-13 next morning I tried again and function normally and can call again.

But today 4-3-13 issue again. probably because ios 6.1.2? Because before I update to 6.1.2, it never happened like this.

I am having the same issue with my iphone 5, and it just started happenign this afternoon. When I try to make a call, it says "call failed." If I try a second or third time it will sometimes go through.

I'm not receiving any calls either . . . it rings twice on the other end and then goes to my voicemail.

My wife just began having the exact same issue as me with her iphone 4s at the exact same time as me today . . . Just started happening at the exact same time.

We are both on t-mobile, but my daughter is on t-mobile on the same plan (except she has a samsung Galaxy) and is having no issues.

Can somebody explain?????? Apple????? Hello?????

Apple is not here. This is a user to user technical support forum. In the US, t-mobile is just starting as a supported carrier for the iPhone. Suggest you check with them to see about carrier support.

I found that my original problem with intermittency and "failed call" notices was due to a problem with the cell tower and not my iPhone 5. Rogers had a technician check on the cell tower that is located closest to my residence and I was told that the problem was related to the cell tower and my phone has been working well since then.

I've had thesame problem with all of my iPhones but it's wrse with my new iPhone 5. It's almost something you cme to accept because your tied in due to the apple content you've purchased from itunes and can't trnasfer.

I wasn't too bothered until today. My father arrived at my door and collapsed in myarms and suffered a major stroke. I needed help an FAST!!!!

The only communications I had was my trusty iPhone 5. I tried to call the emergency services from my phone which showed a full 3G signal. Call failed. I tried another three times still with a full signal and the same hapened. Eventually the call connected and was answered by the emergency opeator and then.... You guessed it call failed. another 2 attempts and I finally managed to summon an ambulance. It took 5 minutes to get connected which is 2 minutes longer than it took the amulance to arrive.

Apple not only have you let me down you have delayed my father from receiving vital emergency treatment. This needs sorting and NOW!

So here's an update from my situation. Hope it helps some folks.

My wife and I had been having some intermittant "call failed" issues on T-Mobile with both my iphone 5 and her iphone 4s. After speaking with T-mobile, apparently they were "refarming" our network area switching out cell tower frequencies to get ready for the new iphone rollout on T-mobile (in early April). They suggested we turn off 3G on our iphones, until all the tower updates take place. . .

We did . . . That allowed us to make phone calls again, but we were stuck on Edge. Not a long term solution, but it would have to do for the moment.

THEN-- The T-mobile carrier update came out for the iphone 5 in mid-april, and once again I started having intermittant fails. This time, I lost the option to turn off 3G (due to the carrier update), so I was stuck wiht a phoen that basically did not work at my home . . . Kapt getting "no service".

So after alot of researching forums, I determined that the problem was BOTH a Handset and carrier issue . . . The original handset I bought was an unlocked iPhone 5, which worked fine on T-mobile when I bought it in December. But as soon as T-Mobile started gearing up to carry the Iphone officially, they started making chancges in their frequency bands . . . Namely,the 1700 mhz aws band. . . . The new iphone 5 that T-mobile began selling in April could pick up the 1700 mhz band. The iphone 5 sold in December could not . . .

And that was the reason for the call fails . . . My phone was jumping back and forth between the 1900 mhz 3G freqeuncies, and Edge netweork frequencies, constantly toggling back and forth, searching, and then going "no service." And it was especially bad at my house . . . apparently because all the towers right around me were being refarmed to accomodate the 1700 band, and my iphone was simply unable to pick that up . . .

So here's what I did.

I went to Apple. I explained the problem. I told them I wanted to exchange it for a new one. They tried to get me to try some software troubleshooting first, but I was adamant about receiving a new phone, and they finally agreed. I made sure that the new phone I was getting was one that was capable of picking up the 1700 and 2100 aws band frequencies . . .

And the problem was solved!!!

So far there is still no solution for my wife's iphone 4s, since there are no iphone 4s phones capable of picking up those frequencies. Right now we're just keeping the 3G off, and waiting. Hope this post helps others with similar T-mobile, unliocked iphone 5 issues.

Hello All,

Even, I had been facing the same issue since feb, but i never cared on it, because I was using nokia as backup another backup number. But considering as this is my primary phone, I got fedup with "call failed", I thought issue my network service provider, hence i changed my network, though problem not resolved, it doesn't make any diff.

Previously i nver gone thorugh this kind of forums, but when i check on net, i found this..so I believing problem lies with handset. my 2nd mobile & my neibhour blackberry has never noticed with kind of issues.

My phone (iphone 5) brand new fractory unlocked, I have purchased it from authorised Apple shop in Bangalore.

Now every day, I feeling like ****..while making calls, sometimes even in middle of conversation (atleast once/twice in day)

If anyone found sol/update.. please post here, so that gets aware of it..

thank you

Texag00, thank you very much for letting us know what was going on! Not many members at this community send feedback when they finally get their issues solved.

I guess I have the same problem here, only difference is that my model is A1429 (not sold here in Brazil, I bought mine in London) and it will never have the 1700 MHz band... my carrier (all carriers in fact) in Brazil are migrating from one technology to another or refarming towers, that is probably why my phone worked perfectly for one week and then got stuck with no voice/sms service.

Hi guys! FOUND THE SOLLUTION

I think I found the sollution. Same problem with my iPhone 5... There is a software bug in the updated version of iOS 6. The automatic "Time Zone" selection is what's causing my problem... I think that it's not functioning well, so it doesn't always register your current time zone, thus you won't be able to make calls. ALTHOUGH you still receive calls and can use network aspps, such as Safari and Whatsapp...

Go to Settings > General > Date & Time and switch of the "Set Automatically"option. Then MANUALLY set your home town and RESTART your iPhone. Do not turn the automatic setting back on. Problem should be resolved..

Hopely with iOS 7 on it's way it will be resolved..

Hope it helps

I have a factory unlocked iPhone 5 with T-Mobile connection, and I was having the same problem of frequent call drops.

I did the following to fix this:

1. From Settings > General > Reset, I reset the network settings.

2. From Settings > General > Cellular, I turned off both LTE as well as Cellular data.

3. From Settings > Carrier, I turned off the Automatic option, and selected T-Mobile.

4. I turned on airport mode and after about 5 minutes, turned airport mode off.

Now I seem to be getting almost zero call drops.

Hello Guys,

I have the same issue right now and accidentaly found the solution on my own. I what did was, specially those users that has LTE enabled. You need to disable it to make a call. Try it...

@ColoradoSid - I did these steps also and even reset my phone and network settings. Try my solution as well. Just turn off the LTE features then booom! You can make a call now...

I've been getting this as well, and has only happened this i've had an iPhone 5. Every now and then ill ring someone and it will come up with 'call failed', or during a call it will just cut out and say 'call failed'

Annoying, thinking of getting rid of the phone and going to Android. Never had this problem with my iPhone 4.

People over pay for Apple Tech, and this is the rubbish we get.... Calls dropping all the time!

I've had the problem since I've had the iPhone 5 I might have 3 bars signal but I can't send or recive calls or text. My job needs me to be on 24 hour call out and I miss loads off calls so I use a £20 Nokia and divert calls to that cos it works. I went to Apple they gave me a new phone I also got a new SIMM and made no difference .im a die hard apple fan but realy I'm going to be looking at other phones now ones that can make phone calls, apple have lost it the 5 is the worst phone I've ever had
