How to Block All Calls Without Turning Off Your Network or Muting Notifications
This will help you stay in control of how and when you want to be available.
Sometimes you just want to get in the zone. I mean fully locked in, with zero calls messing up your flow. And for most people, the first thing we do is either switch on airplane mode or tap Do Not Disturb. I used to do the same thing. But the problem with those is they’re not exactly practical if you still need your network. Like, how am I supposed to stay productive if I can't access the internet, reply to messages, or even get notifications from apps I’m actively using? Do Not Disturb helps, but it’s not always reliable. Depending on your settings, some calls can still sneak through. And sometimes important notifications go completely silent. So it ends up doing too much or too little.
Which is not the best when you’re in the middle of writing something, or managing a task online, or even just trying to follow a thread on WhatsApp without some random number interrupting you.
That’s why, instead of messing with settings you are not familiar with, you can use a call forwarding code that tells your network to redirect all incoming calls to a dead end. It blocks every single call without muting your app notifications or putting your phone in airplane mode.
To get you started, here's how to go about it.

Steps to block all calls on your phone
Step 1. Dial **21*100# and hit the call button.

- What you’ve just done is forward all your incoming calls to a dead line. It won’t ring or notify you, and you won’t get disturbed. But everything else, your internet, your chats, and your notifications will stay active.

To Unblock and Start Receiving Calls Again
Step 1. Dial ##002#

Step 2. Hit call/send

- This cancels the forwarding and brings your line back to normal.

Conclusion
I know it’s a simple trick, but that’s the beauty of it. You don’t need to tweak five different settings or risk missing something important. Just one quick code, and you get what you are aiming for: total focus, no calls, no stress.
So the next time you’re trying to stay in flow, get work done, or just enjoy some uninterrupted screen time without disconnecting from the world, you already know what to do.
