My phone is not able to make or receive calls, why?

"If you have your phone connected to a wireless network in your house, that could be why you can still text, as that will go through the home network first, if connected.

The first thing I would do is connect my phone to my computer, bring up iTunes, back up the phone, and then RESTORE it. I had to do this to mine last night. If that works, great. If not, let us know and we can go from there. Good luck!"

"Those having issues with making/receiving phone calls go through these steps if you need help with understanding how to do a reset and if all else fails a DFU mode reset, I can assist. I am Apple Certified and have access to all service guides.

1Verify that your carrier name appears in the status bar, at top left of the display.

2Turn Airplane mode on, wait for the to appear in the status bar, and then turn it off again.

3Reset Network Settings: Tap Settings > General > Reset > Reset Network Settings.

4If your iPhone is in a case, try removing it to ensure that the case isn't interfering with the cell signal strength.

If these dont work, Contact your carrier to find out the following:

-If you are in an area with network coverage.

-If there is a network outage.

-The account is properly configured to your phone.

Try to restore your phone and set it up as new.

If the above does not work try this Apple Support Article on Troubling a No Service Iphone.

Let me know if this works."

It is probably because you have not bought it from a local carrier. Otherwise, you can try to keep the power button and the selection button downwards pushed at the same time up until the iPhone turns off and then on again. It will erase all the temporary files.

"Hi,all you need to do is toggle Settings>general>phone

See that the Show caller Id to on.

If your phone is jail broken,go Cydia search and install CALLER ID SBSETTINGS ,toggle CALLER ID TO ON.

REBOOT!

It simply worked for me."
