Since upgrading to iOS 7.1 my signal strength varies erratically. Frequently I get "No Service". Signal strength drops from 3-4 bars to 1 and calls fail repeatedly. Anyone else having these issues or have a solution?

please any help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

so tired of this... are iphones are disposable phones!!!!!!!!!!!!!!!!!!!!!!!!!!!!

reply please...

Have you tried resetting network settings and/or resetting your iPhone? You would not lose any information and this troubleshooting often resolved network connection issues.

reset dont do anything neither does changing sim its a software issue as usual and apple dont give a f**k about customers anymore thats whe theres no reply from them as usual!!!!!

This is exactly what my phone is doing!! Mine too was out of warranty and Apple was so gracious 😠 to let me BUY new 4S phone for $225 .... Guess what it TOO has the same issue. So they sent me back to AT&T again and now AT&T is sending me back to Apple. (4th time) So I still have no service but I do have a new phone. 😟 So I'm sure Apple will just try to sell me another phone.... at this point I think NOT!! After three and half weeks of no phone service the majority of the time I am truly disappointed in AT&T and Apple and at my wits end.

What happen Ale do you still have problem? Anyone else??

I'm on iOS 7.1.1, iPhone 5S, same problem. Within 5 minutes, the signal will go from 3-4 bars to 1 bar to Searching... -- I've tried resetting to factory defaults, no restore, and same issue. Will attempt downgrade to 7.0.6 as other poster suggested and see what happens. Hopefully I can do this without losing something. 😠

Well, turns out with 7.1, we can't downgrade to previous versions because Apple won't sign the previous versions. Wonderful 😠😠😠 Here's an explanation: https://discussions.apple.com/thread/5740063?answerId=24380938022#24380938022

Hi Everyone,

Has anyone tried with 7.1.2 to check if the prob is fixed.

i hope its fixed, guys post some good news.

Cheers

No, 7.1.2 did not solve the problem

I upgraded to Ios8...but the sad thing is the prob is not fixed....i lost faith in Apple now....

This prob will never be fixed......we have to live with that....

I am having exactly the same issue on my iphone5 since lsar month. The sim is working absolutely fine on any other handset except on my iPhone 5. its after the upgrade to ios 7.1.2 and now today after upgrading it to ios 8 the problem is still there. "No service" error. I am really frustrated. Was hoping that the software ios8 would fix this issue but.......don't want to loose or change my handset.....people if there is any possible solution to it please let me know.
