IPHONE 4s call failed??!!!

I have been having many missed calls per day, despite having 3-5 bars.

Kjaved, Who is your carrier?

Sprint. Rarely had issue before. Now everyday.

Could some of you post your siri settings?? I think I have this issue since I turned off "raise to speak" thx

Just adding my name to the list of a certain amount of calls where neither side can hear each other yet the call timer says all is good. 4s 32 gb.

The worst phone ever. It's just driving me and my wife nuts...

Just three hours ago The Los Angeles Times reported this: http://latimesblogs.latimes.com/technology/2011/11/iphone-4s-problems.html

I'm in Slovakia using Telekom network, more than 90% of all my calls using 4s either end in call failed. Can't use any SMS too, sometimes is invalid SIM. The worst phone i ever had 😟

I am in UK on Vodafone and have gone from a Iphone 4 with full signal to a Iphone 4s with no signal. It has to be a hardware issue and yet again Apple don't care

I started to drop calls after the latest update, but that is also when I disabled Siri raise to speak. The first 2 weeks I had the phone it didn't drop a single call.

I am using iPhone 4S 32G too, I am having this probleme too. Calling someone, connected, hearing other's voice but he can not hear mine.

Who's your carrier? I don't have that problem on AT&T in the US

same problem 4S, white, vodafoneUK. 16gb

Its still not helpig with it, and also the battery is the same bad. I also tried up iOS 5.1(not 5.0.1) beta 1 and 2. None of the problems are solved.:/

I'm using 4s 16gb and have an exactly same problem in Turkey, Istanbul. Most of times people can't hear my voice.
