At Technical Empire we specialize in fixing the rare “white screen” issue on iPhone 13 Pro Max models caused by screen or board faults.

When your phone displays “No SIM” or fails to detect your network, the issue might not be your SIM card — it’s often a faulty SIM tray or reader. At Technical Empire, we carefully inspect and repair or replace damaged SIM readers and trays to restore proper network connection. Whether your SIM tray is bent, broken, or your device fails to read SIM cards after water or board damage, we’ll fix it with precision parts and expert handling.

We fix network and signal issues caused by faulty baseband chips, helping your phone regain stable connectivity. If the motherboard is completely dead, we perform a professional board swap to recover your device functionality.
