Many users are seeing Call
Failure in Iphone8, iphone X/7/6s and is happening very frequently. iPhone is getting
Call failure message from system, when making/receiving calls. This is really
annoying as the call failure happens now and then on iOS 11 and with almost all
sets Phone X, 8 Plus, 8 iPhone 7, 7 Plus, iPhone 6s, 6s Plus, 6, 6 Plus, iPhone
5, 5s and 5c.
It’s very strange to see that
Apple new phones are not safe from calling issues, users have been reporting
poor signal strength and 100's of dropped calls since upgrading from an iPhone
5 to iPhone 6 plus 64gb phone with iOS 11. They kept getting dropped calls
even switching on to wifi calling. Some users have even had SIM card replaced
and even had my 6 Plus exchanged. My
first iPhone 6 Plus shipped with IOS 8 and had these issues. When upgraded to
IOS it did not help resolve the issues. Affected users have been tryingto
contact Apple for this and apple will say it isn't their fault –
Verizon/service provider will say it isn't their fault - they both know it is
partially and I doubt either care that much because a marginal number of people
are affected. Turning on wifi calling
doesn't work for everyone to fix the random call drops in iphone 6/7.
How to fix iPhone call failed issue :
Solution 1 : Remove your account line from other Apple devices
If you have added any Macs or other devices that can call on your line (iPads, Macs, whatever) REMOVE THEM. This had helped many user and now had perfect call quality on my 6S on Wifi. No dropped calls.
In Settings, Phone, "Calls on Other Devices" - set that to OFF and don't change it.
Solution 2: Change Data settings
Until there is an official launched by Apple, to fix the issue you can try this and may work for you, changed enable LTE to Data only.
Settings> cellular> LTE data only. Not voice and data. Connectivity is much better for me. Seems like could be a Verizon issue.
Solution 3: Reset network Settings and Try noise cancellation to OFF
First you can try to do network reset in your iphone and an hard reboot and please check if it works. Else disable Noise Cancellation. To disable noise cancellation, head on to your phone Settings-> General-> Accessibility-> Noise Cancellation. Toggle the switch to OFF
Fix 4 : Calling Line id
settings
Dial *#31# from the
iphone this will fix any lineId releated issue in your iPhone and make it work
normal.
