My name is ***** ***** certified professional with over 10 years experience. I will be glad to assist you with this.

I am sorry to hear that you are having this issue.

Unfortunately the iPhone 6 sim card is not compatible with the iPhone 4, the iPhone 4 and 4s use the bigger micro-SIM chip which will not work with the newer phones that use the smaller nano-SIM chips. But your carrier can help you swap out that micro-SIM chip for the smaller nano-SIM, most cellular providers will get that to you for free.

Please reply and let me know if you need any other assistance or if everything is good, take a moment to rate my service by choosing one of the stars at the top, then click submit.

Thank you very much!

Expert:  Randy replied 1 year ago.

okay, did you Insert the SIM card into the SIM card tray with the Tmobile logo and SIM card number on top (gold contacts facing down).

Customer: replied 1 year ago.
I get the notification when I insert or remove it. I did that to make sure it was being read.
Expert:  Randy replied 1 year ago.

okay, unfortunately this sounds like the sim card has failed.

Customer: replied 1 year ago.
The sim works in other iPhones perfectly fine it's only this one I'm having trouble with
Expert:  Randy replied 1 year ago.

Okay, that is strange. A factory reset is the only other option to try.

Please follow these steps,

  • Connect the USB cable to the iPhone, but leave the other end of the cable disconnected from your computer's USB port.
  • press and hold the Sleep/Wake and Home buttons at the same time.
  • When the device turns off, release the Sleep/Wake and Home buttons.
  • While pressing and holding the Home button, connect the USB cable to the computer. The device should turn on.
  • Continue holding the Home button until you see the "Connect to iTunes" screen.
  • When this screen appears you can release the Home button:
  • Then use iTunes to restore the iPhone, choose update and restore.
