iphone 4S cannot make outgoing calls

See if this works!

1) Go to Settings > General > Date and Time. Switch off “Set Automatically” and manually select your hometown (the default is Cupertino). If you dont change it, you will not be able to make outgoing calls. But the wierd part is, you will still be able to receive incoming calls. Once done, manually set the date and time, and restart your iPhone. If you want, you can reset the 2 settings to “Set Automatically” again. 2) Next, go to Settings > Phone > Show My Caller ID > Switch this to “ON”.

I also have this issue on mine 4s. It started a bit in and off but got so much worse this weekend when I reset the network settings it allows me to make 1 call but that's it. Very frustrating!!!! Can this be a bug?

This is what worked for me.

Follow "JustJustinn" advice of "Date and Time" followed with a "reset network settings" and then restart.

Its working again 😉

Just a note:

I've disconected my net/wifi while doing this.

Another trouble x(

When I conect the wifi again, I cant make calls.

What worked for me after this was:

general - informations - copy the wifi MAC address and place it on my router wifi options for MAC filters.

Do the "reset network settings"

restart

wifi - (your wifi wont apear you have to putit yourself) - try to make a call - success

Its working, the calls and the wifi at same time 😉

I have an iPhone 5 purchased 9/16/2013. It was activated on Verizon and worked perfectly, even after it was mailed to grandson in Fairbanks Alaska.

After using the phone for about 10 days, one minute he could call out, the next he could not. We have been working with Verizon and Apple ever since to resolve this issue. I found multiple suggestions, most of which we tried. A complication is that Verizon has LTE tower for data and leases Cellular service from a 3rd party.

Rebooted multiple times

Updated to 7.0.3

Reset to New Phone

Recovered from Backup

Did not replace phone or nano simm as the posts indicated that did not help.

toggled Airplane Mode on and Off(mentioned in another discussion)

Turned off International CDMA*(mentioned in another discussion)

There was even a mention that calls lasting longer than 1 minute caused a problem!

Finally turned off Cellular Data and guess what, he could make a call!

He turned Cellular Data back on so we will see if that causes a problem again. If so, it is a pain, but he can turn it off and back on to cause a hangup. He mostly uses instant messages anyhow.

Since iPhone 5 can not use data(except wi-fi) and make calls at the same time, it seems like something was using data and not allowing an interrupt to dial a call out, even though incoming calls were successful. iPhone 5 has so much stuff going on in the background that uses data constantly for location services along with other apps like maps, weather, find my friends, etc. Seems like a bug in there somewhere.

Igraha,

Wow! You've brought to light something important!

It is a fact that on carriers such as Verizon and Sprint that uses CDMA,

the iPhone5 can not do data and voice at the same time.

On iOS6.x, whenever a voice call is going on, and data access attempted,

a dialog box would pop up saying that data can't be done at the moment.

And if there is a data session already in progress and a voice call is attempted,

the data session would be paused to make way for the voice call.

Now on iOS7.x the operating system allows other apps to be run in the background.

Suppose there is a bug in iOS7.0.2 that doesn't pause the background apps?

Would you try turning of the background app refresh then see if the problem goes away?

Additional info about what caused the problem in the first place>

From Verizon: They actually admitted there is a problem with a new program which is called Family Base

Usage control causes the device not to be able to place calls when roaming with certain partners and may not supported outside of the verizon wireless network

usage controls will need to be deactivated in order for you to make calls while roaming on extended networks.

if you want to keep the usage controls you will have two stage dialing you would follow steps below:

Dial 800-922-0204 and Press send

you will get a msg that states please enter number again and do not press send

input 800-922-0204 this time do not press send there will be a little delay but call will go thru if you press send call will not go thru.

i have this exact problem! what do i do?

The fix for our grandson's phone had to do with Verizon and their Family Base control program. Verizon notified us that the Family base caused problems with phones on non-verizon phones. We cancelled Family Base and turned the cellular data off and back on and that fixed it. It has to do with cellular data capturing the "radio" in the phone and not pausing to allow outgoing calls to be initiated. sometimes others have been able to interrupt the data stream long enough by toggling off and on the Airplane mode or just temporarily turning off Cellular data. this is especially problematic if there are background programs using data to constantly keep track of your location like Find my Friends, weather, etc.

Good luck!

i had a problem with iphone 4s and making outgoing calls after changing the operator and moving my old number to the current operator. Everything was ok except for making outgoing calls which occured everytime as connection failed. Strangely but after trying to make a facetime call which btw was successful, I was again able to make normal outgoing calls.

I know it's rather strange solution, but I thought it might be helpful for someone having similar problem. I don't know why it worked, but I know that it worked as I applied evry other solution with no success. After this it started working.

Thx this solved my problem

So after a long process of looking up things and calling at&t we finally found the problem if you got a new phone and did not call the company your imei code is off and you need to call them i did this and it fixed my problem normally you dont need to but it is best to i had the problem where i would restart my phone and then i could only make one phone call not saying this is your problem but i would give it a try call your company and tell them that you want to make sure that your imei code is correct.

After a desprate search I found this community and It worked for me.

Thanks to All

I temporary fix it by dialing *#31#.

It shows a message "Setting Interrogation Succeeded, Calling Line ID Restriction Disabled" and then can call normally.
