Could not activate iPhone or iPad after updating to iOS 9.3
Have you got an activation error “Could not activate iPhone” or “Could not activate iPad” after updating on iOS 9.3? Below is described how to solve this problem.
If you can‘t activate your iPad or iPhone
There are several reasons of error.
The main reason is that it may be the first release date of iOS 9.3, that is why so many owners of iPhone and iPad try to update their Apple’s devices on the latest firmware. Everyone wants to be in the first raw of happy users of iOS 9.3. Apple’s servers are powerful enough on the one hand. On the other hand 1 billion Apple devices are in active use around the world [proof link]. Can you imagine so many owners of Apple gadgets want to upgrade their favorite iPhone/iPad in the same time? It’s obvious that Apple’s activation system is overloaded because of huge traffic. It looks like traffic jam. The best thing you can do in this case is to relax to wait for some hours until traffic goes down. There is nothing you can do when activation server is unavailable. So calm down and wait for some hours until traffic jam is disappeared.
Do you usually update firmware on iPhone/iPad via Wi-Fi? You can update your Apple device’s firmware via iTunes also. First make sure that you use the latest version of iTunes [it is there].
One more reason of error is that a SIM card you are using is unsupported. Make sure the SIM card is inserted in your iPhone. It does not matter whether you have an active contract or not, your iPhone needs the SIM card for activation. No SIM or Invalid SIM alerts appear when a SIM card is damaged, locked, or missing. If a message says to sign in with an Apple ID to activate just do it or learn about activation lock.
Follow these steps
- Find the list on the system status page. If the box next to iOS Device Activation isn’t green, try activating your iPhone later.
- If asked for a password, enter it. A password prompt means Activation Lock might be enabled in Find my iPhone.
- Restart your iPhone.
- If you’re using a cellular data connection, try connecting to a reliable Wi-Fi network instead. If a Wi-Fi connection doesn’t work, try connecting to iTunes.
- If you’re using iTunes to activate your iPhone, make sure that iTunes is updated to the latest version.
