Call doesn't get connected while using wifi (3G cellar data when kept on)

Question

Call doesn't get connected while using wifi (3G cellar data when kept on)

I have recently bought an iPhone 5s and have started experiencing this problem after my recent iOS update. Whenever I am switching on the wifi keeping my cellar data and 3G on , I am not able to receive or make a call. I have to restart to make a call and turn the wifi off.

Again when I turn the wifi on the same problem is faced.

please help out, do i need to get my iphone replaced? Or is this a bug which can be fixed?

iPhone 5s, iOS 7.0.4

Hey samratrzurange,

These step are for troubleshooting issues making or receiving calls:

Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.

Check your phone settings:

Check your Do Not Disturb settings: Tap Settings > Do Not Disturb.

Check for any blocked phone numbers: Tap Settings > Phone > Blocked.

See if Call Forwarding is turned on: Tap Settings > Phone > Call Forwarding.

Ensure that your software is up to date:

Check for a carrier settings update.

Check for an iOS software update.
Note: Some updates may require a Wi-Fi connection.

If the iPhone has a SIM card, reseat the SIM card.

If the iPhone 4 or iPhone 4s is on the Verizon network, dial *228 from the iPhone and select option 2 to update the Preferred Roaming List (PRL). The PRL determines the cellular towers the phone uses for cellular service, selecting those with the best signal strength.

Reset the network settings: Tap Settings > General > Reset > Reset Network Settings.

Try to make or receive calls in another location.

Attempt to isolate to one network band:

If you're having the issue on LTE, disable LTE, if possible, and try again.

If you're having the issue on 3G/4G, disable 3G/4G, if possible, and try again.

Contact the carrier to check the following:

Your account is properly configured to use the specific iPhone that has the issue.

There are no localized service outages.

Your account doesn't have a billing-related block.

Your calls don't have errors on the carrier system.

Restore the phone as new.

If the above steps don't resolve the issue, go to an Apple Retail Store, carrier, Apple Authorized Reseller, or contact AppleCare to send the phone in for service.
