I cannot receive incoming calls on my iphone 5s

The Contact Us link at the bottom of the page was of no help? What country are you in? Most have at least a regional number if not a country-specific one.

Contact Apple for support and service - Apple Support

What specific settings did you try? X and Y don't help us determine what troubleshooting you may already have done. What exactly does it mean when you say you cannot receive calls? Are you sure Do Not Disturb isn't turned on?

Your employer recently upgraded to a version of IE first released in March, 2009 and already three major releases behind? I see your struggles now.

Anyway, I suspect this may be an issue with your mobile carrier profile on the iPhone. Check in Settings > General > About. Do you get a message to update/u[grade your operator settings? If not, then check what is listed in the Carrier filed on that settings page. Verify with your operator that you have the proper one.

Also, you never mentioned what country. I can provide the contact info you need.

You do no one any service by being so antagonistic when somebody posts with a serious problem. You need to either tone down your nasty or stop posting.

Umm, have you gotten lost and posted in the wrong thread? Antagonistic? Excuse me? You address me directly with a comment like that for what exactly?

I don't know what you're even referring to, but Belgar Lad and I are working through his serious problem so please move along unless you have something to add besides your snippy - and apparently misguided - comments.

A couple more questions...

I'm not sure what you mean by "...and when selected it changes to PRL and has a '1' as its setting. Select again and it defaults back to carrier." I am not able to select or affect a change in any of the fields on the Settings > General > About page. Is that what you're saying?

Are you switching SIMs on your deployments to Angola or are you just operating in a roaming environment?

Finally, it sounded like EE focused on you and the device settings during your support call, but did they take the time to be absolutely certain that they have everything set up correctly on their end?

Strange. I'm not able to tap or change anything on the About screen for any of the four devices I have here. I have never seen or done that before. Perhaps this is the anomaly that is contributing to your problems. Maybe someone else has experience in seeing this, but unfortunately I don't.

Finally, to answer your question - no Apple does;t do anything to control your calls. It is completely under the domain of the mobile operator, either through your account with them, or the operator profile identified in Settings > General > About

Yet a couple more questions:

Have you since tried to see if your old phone - or any phone for that matter - can receive incoming calls while in Angola? That might help to track down where the issue lies.

Is this a company-issued phone or your personal? Has it been provisioned for enterprise deployment?

Can you check in Settings > General > Profile and tell me if you have any certificates / config profiles there?

Ok, I think we're getting somewhere. PRL refers to the Preferred Roaming List. From what I've read, normally, this doesn't need to be updated manually on GSM phones however, it seems iPhone running on CDMA operators sometimes require it. I don't understand why your phone is even showing this.

All of that means I am almost certain this is an issue with your operator profile. Maybe it didn't load properly - I don't know - but seems that is where the trouble may be.

I would suggest you either address this with them or restore the iPhone as new. I'm afraid that restoring from a backup will reintroduce the problem. I don;t think there is a way to force a read of the profile except to maybe install a SIM from another operator. Again, maybe best to speak to your operator first.

Just to see if it helps, the second post here describes how to update the PRL on Sprint in the US. Maybe give it a try to see if it helps at all. I don't think it will do any damage.

Good luck. Let me know how it goes.

Hi, I know this post was from a while ago, but I'm having the exact same issue, including the PRL 1 phenomena in the Carrier field under GENERAL/ABOUT. I was wondering if you managed to solve your problem. Im using an iPhone 6, which I tried restoring to factory settings and setting up as new phone, then also restored from a recent backup, with no luck. Problems began a couple of weeks ago when I inserted a SIM card from a different carrier during a trip, which worked fine, but when I got back home, my phone wouldn't get back on my local cellular network. After one of the carrier's authorised representatives performed a reset or deleted some settings, everything working fine, at least for a few days. Then all of a sudden it went back into to an persistent SEARCHING... mode without finding any carrier or network. During a second trip to the carrier's office, the rep did a basic reset and also inserted a brand new sim card. Again, everything worked fine for about two days, but this morning the problem resurfaced. It does detect that a SIM card is installed, but its as if the network were down (which it ain't). Thanks for any help!
