Could not activate your iPhone? Here are some possible reasons that might be responsible for this problem.
After knowing what causes this problem, you can take some proper measures to fix the "could not activate iPhone" issue. If you don't know what to do, some proven methods in this guide are worth trying.
The first solution should be checking your SIM card to see if it is compatible with your device or inserted properly. If you're not sure whether the SIM card is compatible with your iPhone or not, you can try inserting a different SIM card to see if it works. If it still doesn't work, that means it's not the SIM card's problem.
If you're sure that there is no problem with your SIM card, try rebooting your device to give it a fresh start and fix some small issues like the cellular data not working on iPhone, iPhone keeps crashing, or iPhone keyboard not working, etc. Also, the "iPhone could not be activated" issue is also possible to be addressed by performing a simple restart. But keep in mind that this is not a one-fit-all solution, so you'd better use this method reasonably.
Sometimes, a weak internet connection may also stop you from activating your device. So, you can go to check your network condition to see if it goes wrong. If it does, you can try connecting to a stronger WiFi network to activate your device.
If it still doesn't work, just try activating your iPhone with iTunes. To do this, you need to plug your iPhone into the computer > Turn off your iPhone and reboot it > Open the iTunes if it doesn't open > Then, iTunes will automatically go through the activation process > Proceed by entering your Apple ID > Click "Continue" to complete the activation process.
