iPhone 16 (A3287) cellular service fails to activate after restore

Title:

iPhone 16 (A3287) cannot be activated after restore: “Cellular service could not be activated on this iPhone”

Question:

Hello,

I recently purchased a used iPhone 16 (model A3287) and am unable to activate it after restoring the device to the latest official version of iOS.

During the activation process, I receive the following message:

“Cellular service could not be activated on this iPhone.”

Here is the situation in more detail:

  • Before restoring the device, cellular reception was extremely weak.
  • Outgoing calls did not work.
  • The SIM card is detected correctly.
  • Modem firmware is present and displayed in the device information.
  • As far as I can tell, the device does not appear to be carrier locked or blacklisted.
  • When attempting to restore the device through a computer, the process failed with error 9 (130A.0000).
  • After successfully restoring and updating the device to the latest iOS version, the activation issue remained unchanged.

Because the SIM card is detected and the modem firmware is present, I am not sure whether this is an activation-related issue or a hardware problem affecting the cellular subsystem.

My questions are:

  1. Is there any way to determine whether this device has an activation-related restriction or server-side issue?
  2. Could the combination of symptoms (weak cellular signal, inability to make outgoing calls, activation failure, and restore error 9) indicate a hardware fault involving the baseband/modem, RF components, or the logic board?
  3. Are there any additional diagnostics I can perform before taking the device to Apple or an authorized service provider?

Any advice or suggestions would be greatly appreciated.

Thank you.

Hi there


Please try this


  • Check Carrier/IMEI Status: A carrier lock or blacklist usually triggers specific prompts regarding an incompatible/invalid SIM or a carrier restriction message, rather than a total failure of the phone's internal cellular service module or a hardware-tied Error 9 during a restore. 
  • Verify via Computer: Connect the iPhone to a Mac (Finder) or a Windows PC (Apple Devices app/iTunes) with an active internet connection. If the computer finishes restoring and prompts "Set up as New" or "Restore from Backup", the device has successfully passed Apple's activation handshake. If it fails or loops back to the cellular activation error, the phone is failing to communicate valid hardware/security identifiers to Apple's servers.

Error 9 is a communications error with the computer: If you see error 9, 4005, 4013, or 4014 when you restore your iPhone, iPad, or iPod touch - Apple Support. It has nothing to do with the cellular problem.


When you got the phone was it reset to factory settings-It should start with a Hello screen, then lead you through setting it up as a new phone. If not, return it.


Is this a new SIM card? If not, get a new SIM card from your carrier.


Did the problem occur before you restored any data to it? If not, set it up again.


Have you checked that it is not blacklisted: CTIA Stolen Phone Checker
