title：How to Make Phone Not Reachable While Keeping Internet Active

content：How the "Not Reachable" Trick Works

Ever wanted to use your phone’s internet without being disturbed by calls? Maybe you’re in a meeting, studying, or just need quiet time. The Technical Expert Baba YouTube channel shares a simple trick to make your phone appear unreachable while keeping data active. This method uses USSD codes to redirect calls to an inactive number, so callers see "not reachable" but your internet stays on.

What You Need First

You’ll need an inactive phone number (a disconnected or unused number). Using an active number will redirect calls to that number instead of showing "not reachable."

Activate the Trick

1. Open your phone’s dialer app.
2. Enter the code: *401*[inactive number]# (replace [inactive number] with your disconnected number).
3. Press the call button. The call will auto-disconnect—this confirms activation.

Test the Trick

Use another phone to call your number. You should see a "not reachable" message (or similar, like "call failed") depending on your network.

When you want to receive calls again:

1. Open the dialer app.
2. Enter *402# and press call.
3. The call will disconnect, and your phone will start receiving calls normally.

• Inactive number rule: Never use an active number—this will send calls to that number instead of blocking them.
• Network compatibility: This works on most GSM networks (e.g., Airtel, Jio, Vodafone). If it fails, check your provider’s support for network-specific codes.
• Internet stays active: Your mobile data or Wi-Fi will work as usual—browse, message, or stream without interruptions.
