iPhone 5 CALL FAILURE on Vodafone Mumbai

Just to update you all, Sunday 06-Jan, I had restored my iPhone 5 and setup as new iPhone without restoring backup. Got network update and ignored it (not now). Since past two days that's Monday and Tuesday I haven't faced any call failed error message on my iphone5.

even i wasted 2 hours,, its not working,, I think,, there is something wrong with vodafone network... did anyone try with other network sim cards?

Hi Everybody,

An update for all of you having "Call Failed" issue on iPhone 5 in Mumbai on Vodafone Network.I also had similar problem like i have mentioned earlier.I went to Vodafone shop in Mulund twice and tried replacing the nano SIM.Also tried restoring like a new phone.But after all this, the problem persisted.Vodafone guys told me that there is no problem with their network and the problem lies with the Phone.

I then went to Apple Service Provider in Thane who also confirmed the problem and agreed its a hardware issue.They have replaced the defective iPhone 5 with a New iPhone 5.

Trying out the replaced iPhone 5 now and not having any problems as of now.Will update if problem arises.

So the conclusion is that the problem is an iPhone hardware problem and needs replacement.So visit the Apple Service Center at the earliest.

hi drprasad,

Can you please mention your time duration (no. of days) to get back new replacement handset from apple store.

or you have got new replaced handset on the spot?

I have the same problem in Delhi. Got a new nano sim, but the problem persists!

Tried using Idea, no call failed error on it. Its not a hardware issue.

It just took 1 day.I have an iPhone 5, White, 32 GB.Replacement time depends on whether iPhone similar to the faulty one is available in stock with them.

I've the same issue using the Vodafone on iPhone 5 which I purchased in mid-Dec. I changed my SIM card twice from the Vodafone CC. That fixed nothing. So I'm assuming its not a problem with the SIM card atleast, can't say about the carrier.

Yesterday i visited iStore Thane, they said wait for an update to come as they were very much aware of the issue. But I resisted as I didnt find the problem with iOS. In that case it'd be with all the iPhone 5. So I asked them to replace it. So far, I've not receive the replacement. However, reading this forum, I can say that neither carrier nor the manufacturer knows the defect.

Please keep posting the remedies one took to rectify the defect. Thanks !

I am facing the same issues in my shining iphone 5...Call drops freqeuntly .. Please help to solve this issue.

Are you using Vodafone cellular services?

yes i m using vodafone services..

This problem seems to be with Voda only... Although I've seen an Airtel user wid the same problem. But that was a single case among 10 voda cases.

Did you get your iphone replaced?

Not yet ! Still waiting.

I had given my iphone5 for replacement at service center (14th-Jan).

I just told them I am facing so-n-so problem.

They did some diagnostic tests and informed me that it will get

replaced within 2-3 working days.

I was not getting any call failure after doing below procedure :

1. Erased all data and settings and setup phone as new. (not from backup)

2. Not updated the Network operator (Vodafone) update.

Used phone for a week with this condition and no call failed. But still i thought its better to replace the handset rather not

applying operator settings.

I hope so with new handset this problem will get resolved.
