Call Failed message on iPhone 5c (very frequently in various locations)

[mgthomason]

Hi I wonder is this a known issue? is there a setting I need to change etc?

New iphone 5s 32gb, 2-3 weeks in, I keep getting "Call Failed" messages during my conversations at which point the call does indeed fail - I then need to redial and I can reconnect, sometimes these subsequent calls also fail .... this will happen on at least 50% of my calls, calls from varying locations, on call of varying call length, to both domestic and internaitonal numbers.

I recently upgraded from my iphone 4 8gb - used in all the same locations etc  - no such issues. 

Anyone able to help? faulty device? is is device design? is there a device setting? 

Vodafone any thoughts?

Thanks in advance for any contributions.
