How to unlock Nokia N73 without code?

Unlocking a Nokia N73 without a code is possible, but only if you know the phone's security code or use specific software.

### Method 1 – Default Security Code
Many old Nokia phones use `12345` as the default security code. Try these:
- `12345`
- `00000`
- `54321`

### Method 2 – Master Code
Online master code generators exist for old Nokia models. You will need the phone's IMEI (found under the battery, or by typing `*#06#`).

⚠️ Warning: Some methods only work if the phone is not network-locked.

### Method 3 – Hard Reset (data loss)
If you don't need to save data:
1. Turn off the phone
2. Press and hold simultaneously: `*` + `3` + green call key + power button
3. Keep holding until the Nokia logo appears

**Conclusion:** First, try `12345`. If it doesn't work, search for an online master code generator using the IMEI.
