HI,
Tap Settings / General / Reset / Reset Network Settings.
That will revert to factory settings but may help.

Iphone 5 can't make/receive calls/text (possibly 2g issue)

Hi,
Just obtained an iPhone 5 on t-mobile. Everything seems to be working fine including 3g network/wifi. However, I can't make/receive any calls. I get full reception, EE written on the top left but outgoing calls always fail. Incoming calls also fail. I've checked with t-mobile, my SIM is fully activated and have also successfully tested my SIM in another iPhone 5.
I've tried Apple's troubleshooting assistant here http://www.apple.com/uk/support/iphone/assistant/calls/. None of these worked.
I've got an appointment booked in with Apple on the 14th but was hoping there might be a quick fix I can sort myself before then. Is anyone else having this issue?
Any help is appreciated.
Thanks,
Yasin

You restore the phone as new to get rid of the passcode.

I can't make/receive calls on days old iPhone 4. Just says Call Failed.

Same thing is happening with my girlfriend's 3Gs. The person being called hears half a ring then phone cuts out. I have all bars but when call fails bars all drop for a moment, then return. I've reset network settings and everything else. What the **** ****!?
Not sure if it's an AT&T issue, or iPhone or both. I drove out of town and was able to make calls again. Once i returned the problem resumed. I called AT&T and they have no knowledge of network outages in my area. My girl's co-worker (also an iphone owner-3Gs) is having the same issue.
I put up with AT&T's horrid service with crappy coverage and failed calls all the time but this is far worse. I CAN'T USE MY PHONE!
Somebody please help me before I murder this thing and buy a Droid X.

Thank you for your reply. Unfortunately, it does not make a difference. It still shows "iPhone not available. iPhone and Mac have to be in the same network"
Are there any settings which are fundamental on the iPhone, I have activated:
- iCloud Drive
- FaceTime (FaceTime and iPhone Mobile Calls activated)
The only strange thing - on Yosemite I can activate mobile phone number AND email in FaceTime whereas I can activate just my email in the FaceTime app on my iPhone...

HT4061 my iphone says "iphone is disabled". i can receive calls but can only make emergency calls.help plz

going nuts. thought i had a great deal. bought a iphone at a flea market for 35 dollars . got a sim from straight talk and a monthly service . got old number from my tracfone transfered to the iphone, but phone says it is disabled and i cant call anything but emergency numbers. my friends can call in but i cant call out or use apps .

It might have been reported stolen and remotely disabled. You can try booting into recovery mode and then connecting to iTunes:

I connected to itunes on my computer to and i updated my iphone and now the SIM is not recognised so I can only make emergency calls

iTunes offered to update my old iphone to version 3. something and now the phone doesn't work because it says the SIM is incompatible.
This is the sane SIM that was working fine before the update.
I even uploaded some photos.
How can i get back the old version of iphone software so that it accepts my SIM

The original owner has a new iphone and he gave me this one. All we did was put my SIM card in and it worked; I'm sure he didn't have to hack it to unlock it. He just had this old phone lying around.
How can he authorise unlocking it if he doesn't have the same SIM anymore -he'smoved countries a few times.

HT201401 my iphone will not boot up with 02 simm in itune can only make emergency calls done factory reset still not working

The sim card inserted in this iphone does not appear to be supported
only compatible sim cards from a supported carrier may be used to activate iphone
please insert the sim card that came with your iphone or visit a supported carriers store to receive a replacement sim card

So have you done as the message advises and visited a store to get a replacement SIM?
Did you purchase the phone on a contract with O2 or with another provider?

I can only make emergency calls from my iphone 4. How do I fix this? Not tech savvy in the slightest !!

I've just recently bought a white iphone formy daughter and am trying to put my sim into her old one but can only make emergency calls. How do I get round this? Not tech savvy at all as you can probably gather. Thanks

Did you connect your iPhone to the computer and sync it with iTunes? You will need the internet as well as Apple will unlock your iPhone over the internet via iTunes. Let us know if this helps.

I have no idea why this has happend ive been using the phone for 2years bought it on pay as you go and now all of a sudden its stating the above error i have never come across this problem before and currently im using 3GS and Iphone 4S

Sounds like it's been blacklisted.
Even if it hasn't, downgrading voids any warranty and forfeits all rights to support. You hacked your phone. You can't get help here.

I have an iPhone 3gs and it used to show up on my computer, but now it shows up on my screen that it is charging however, does not appear in iTunes or My Computer so i can't sync it. Can anybody help? Thanks

Did you already make sure that Apple Mobile Device Service is installed and active on your computer?

HT1414 Hi team, my iPhone 3gs has no service

Hi team, my iPhone 3gs has no service. How I can resolve this problem

Did you try removing the SIM and inserting it again?
Have you spoken to your carrier about getting a new SIM?
Have you tried the basics from the manual? Restart, reset, restore

Upgraded to iOS 5 on my iphone 3gs now phone service doesn't work and battery does not hold charge. Can someone help me?

It appears to be a bug in iOS5. I have the same problem on the 3Gs and my new 4S.

My iPhone 4 shows the carrier name, I can go online with my data plan, but there are no bars and I can't make phone calls.

My iPhone 4 shows the carrier name, I can go online with my data plan, but there are no bars and I can't make phone calls.
It worked for some time, less than a week, I made phone calls and all, and all of a sudden the problem mentioned above happened. Now I can't make any phone calls. I can go online with it, even with my Data plan, I can go to the app store (of course) but can't make any phone calls.
Please help, this is frustrating.

Did you already try the troubleshooting mentioned here? http://www.apple.com/support/iphone/assistant/calls/
Also try to reset the phone by holding the sleep and home button until the Apple lo comes up again. You will not lose any data doing this.

IPhone 3GS 32GB, no service/searching

I have an iPhone 3GS 32GB, i recently updated to iOS 6.1, and since then my phone is always searching or i have no service, i will get a message saying i need to restore my phone with itunes. I am on GiffGaff network and the carrier setting are all input correctly.
I will restart my phone and then i'll have the iOS lock screen where i can only make emergency calls from, I cant unlock my phone to access anything, no music etc. Sometimes i will turn my phone on and off and the problem will be rectified, but then it will just lose signal again and i will be forced to restart over and over again until i can acces everything.
Its very unreliable as a phone now, any help and suggestion would be greatly appriciated.

These are the screen shots i've managed transfer to myself while i was able to to get wifi.
