## What are Secret Codes?

Secret codes (also called "engineer codes", "service codes" or "USSD codes") are key sequences that unlock hidden functions in mobile phones. They were originally created by engineers to:

- **Diagnostics** — Test hardware and software in the factory
- **Unlocking** — Remove SIM or operator locks
- **Reset** — Restore the phone to factory state
- **Configuration** — Set advanced network parameters
- **Information** — Read hidden technical data

Most codes work by dialling the sequence on the keypad and pressing the call button.

## ⚠️ IMPORTANT WARNINGS

🔴 **FULL RESET** — Codes like `*#7370#`, `*2767*3855#`, `*#*#7780#*#*` **delete ALL data** — contacts, messages, photos, apps. Always make a backup first.

🟡 **SIM UNLOCKING** — Unlock codes must be provided by the operator. Repeated incorrect entries can permanently lock the phone.

🟢 **SAFE CODES** — `*#06#` (IMEI) and `*#0000#` (software version) are completely safe on any phone.

## How to Find the IMEI of Your Vintage Phone

**Method 1 — Universal code:** Dial `*#06#` on any mobile phone. The IMEI appears on screen.

**Method 2 — Under the battery:** Remove the battery — the IMEI is printed on the label underneath.

**Method 3 — Original box:** The barcode on the original box contains the IMEI.

**What the IMEI is used for:**
- Verify the authenticity of the phone
- Unlock the phone from the operator network
- Report theft to authorities
- Check if the phone was previously stolen

## History of Secret Codes

Secret codes were born in the 1980s when Nokia, Motorola and Ericsson engineers needed to test prototypes in the factory without disassembling the device.

The `*#06#` code for IMEI was standardised by ETSI (European Telecommunications Standards Institute) in 1991 with the introduction of the GSM standard — it has remained unchanged for over 30 years.

With the arrival of Android and iOS smartphones, many traditional codes have been replaced by diagnostic menus integrated into settings. But on vintage phones from the early 2000s, secret codes remain the only way to access this information.
