How to Make Phone Not Reachable Without Flight Mode (2024)

content: Ever Been Disturbed Mid-Task? Try This Trick

Ever been in the middle of a crucial game or work task, only to be interrupted by an unwanted call? You don’t want to turn off your phone (since you need internet) or use flight mode (same issue). The Technical Expert Baba YouTube channel shares a clever trick to make your phone show "not reachable" to incoming calls while keeping your network and internet active. After analyzing this video, I’ve broken down the steps and added key tips to ensure it works for you.

The trick relies on call forwarding—a carrier-supported feature—to redirect incoming calls to a disconnected number. When someone calls you, the call is sent to a number that’s either turned off or has no balance, so the caller sees "not reachable" or "out of coverage." The best part? Your internet and network stay active, so you can keep using apps or browsing. This method works across most mobile carriers, as call forwarding is a standard feature.

Let’s get to the practical part. Follow these steps carefully to avoid mistakes:

Activation Process

1. Open your phone’s dialer app (the default one for making calls).
2. Dial the USSD code: *4001*[disconnected number]# (replace [disconnected number] with an old SIM number that’s no longer active or has no balance).
3. Press the call button—you’ll get a confirmation message or the call will disconnect automatically, indicating activation.

Deactivation Process

Forgetting to deactivate this trick can lead to missed important calls. Here’s how to turn it off:

1. Open the dialer app again.
2. Dial *4002# and press the call button.
3. The call will disconnect, and the forwarding will be deactivated—test with another call to confirm.

Key Tips for Success

• Use a truly disconnected number: If you use an active number, calls will be forwarded there instead of showing "not reachable."
• Test after activation: Call your number from another device to ensure it shows "not reachable."
• Save the deactivation code: Keep *4002# in your notes to avoid scrambling later.

This trick is perfect for:

• Gaming sessions where interruptions ruin your streak.
• Work meetings or deep focus tasks where you need internet but no calls.
• Times when you want to avoid spam calls without blocking every number.

Alternative methods (like Do Not Disturb) have limitations—Do Not Disturb still lets calls from favorites through, and blocking requires adding each number. This trick is faster and more comprehensive.
