Activating an iPhone is the first thing you do when you use the device for the first time or after restoring it to factory settings. However, there are instances where you may face activation failure on iPhone, preventing normal usage. Don't worry too much if you face this issue, as there are reasons you can resolve at home without taking the device to a store or repair shop.
What to do when iPhone encounters activation issues?
1. Causes of iPhone activation issues.
+ Apple Server Issue: If you are facing activation problems, it could be due to a temporary issue with Apple's activation server. The server might be congested or overloaded, preventing you from activating your iPhone. Usually, you'll see a message on the screen saying: The activation server is temporarily unavailable.
+ Using Locked iPhone (Network-Locked Version): For users of network-locked iPhones who do not use a SIM adapter but directly insert a SIM card from carriers like Viettel, Vinaphone, MobiFone, or Vietnamobile, you may encounter an invalid or unsupported SIM, leading to activation failure. Typically, the screen will display: Sim not Supported
+ Internet Connection Issue: If you see the message Activation could not be completed on the screen, it indicates that there is an issue with the WiFi internet connection during the activation process, resulting in iPhone activation failure.
2. Resolving iPhone Activation Issues.
+ Check the SIM Card: Whether you are using an international version or a locked iPhone, it's essential to check the SIM card in use. For international versions, ensure the SIM is inserted correctly and fits snugly in the SIM tray. For locked versions, check if the SIM adapter is properly installed before inserting the main SIM card.
Currently, some types of SIM adapters for locked iPhones cannot activate, while others may activate but get deactivated shortly after. The reason behind this is that in the past few months, Apple has patched a serious vulnerability, preventing locked iPhones from being activated internationally using the so-called 'magic' SIM adapters.
+ Check Apple's System: You can visit Apple's system website HERE. Scroll down and find the iOS Device Activation section. If the activation server is busy or temporarily unavailable, it will be displayed in yellow. If the activation server is working well, stable, and available, it will be shown in green as illustrated below.
+ Choose a Stable Internet Access Point: To determine if your internet connection is fast or slow, refer to the article on Measuring Network Speed with Speedtest.
+ Activate iPhone with iTunes: Download the latest iTunes version on your computer or laptop. Connect your iPhone to the computer to access the iTunes application. The activation window may appear immediately. Follow the steps on the iTunes app to begin activating the device.
Download: iTunes various versions
+ If after trying the above cases, you still cannot resolve the iPhone activation issue, it's time to bring your device to repair centers or stores. The staff there can identify and fix the problem for you.
