Another easy trick to make your phone not reachable is by removing the SIM card. Just switch off your phone, take out the SIM card, and then insert it back in without turning the phone on.

Trick 6: Call Barring

If you want to make your phone unreachable for everyone, you can turn on the Call Barring feature. You can find this option in your phone’s network or operator settings. Call Barring allows you to block both incoming and outgoing calls. When it is turned on, anyone who tries to call you will hear a message saying that your phone is switched off or unreachable.

Even if your phone is not reachable, your SIM operator will still record who tried to call you. This means you can still see the caller’s name or number later. For example, Airtel users can check this using the Airtel Thanks App. Some mobile operators may charge extra money for this service. It is always a good idea to check with your mobile company before using it.

Trick 7: Change Network Preference

Manually changing your network is an easy trick to make mobile phone unavailable. Just shift your network quality option with Disable VoLTE/5G. Many phones now allow toggling VoLTE or 5G. This can disrupt call connectivity in some scenarios.

Because of this, your device may show a temporary network error. When someone tries to call you, they will hear a message saying that the number is currently unavailable and they should try again later. This makes it look like your phone cannot be reached.

Trick 8: AI Call Screening

Smartphones today are coming with AI integrations at various levels. While they help in building a more intuitive experience, they act like your assistant in little ways. This includes handling calls. AI call screening feature can make you seem unreachable to spammers or unknown numbers.

Trick 9: Block The Number

Blocking a phone number directly makes your number not reachable for the caller with the blocked number. So, unless you unblock the caller, he or she won’t be able to contact you by calls or SMS. But if they are using social media to reach you out like an Instagram call or Facebook call, this action won’t stop that. The apps use a separate network channel. So proceed with this knowledge. To block any particular number, follow the steps below:

When you block someone’s number, the caller may hear different messages. This depends on your phone model. Some phones make the caller hear “The number you have dialled is busy”. This makes it sound like you are already on another call. Other phones may tell the caller that the number is unreachable. It can sometimes reveal that you have blocked them.

So before blocking a number, think about whether you are okay with the caller knowing that they have been blocked. Different phones show different messages, so the person may or may not find out.

Pro Tip: First, test these methods to make your mobile phone unreachable. You can do that by blocking one of your other or alternative numbers. Then call your device from that number.

You can even use third-party apps like “Truecaller” to block calls. This might not make the number not reachable. But, this will make the calls disconnect as soon as the caller calls your number.

Trick 10: Voicemail Divert

You can turn on the voicemail service on your phone and record a message. It can be something like, “The number you are trying to call is switched off” or “The number is out of network coverage, please call later.” This trick makes people think your phone is off or not reachable, even if it’s actually on.

Steps to Set Up Voicemail Divert

1. Open the Phone app on your mobile.
2. Go to Call Settings.
3. Select Call Forwarding or Call Divert.
4. Choose when you want calls to go to voicemail. You can select multiple options from there. These include Always forward, when busy, when unanswered, and when unreachable.
5. Enter the voicemail number given by your service provider.
6. Tap Confirm or Save.
7. You’ll see a small icon or message showing that call divert is active.

Trick 11: Focus or Priority Mode

Use Focus Mode (iOS) or Priority Mode (Android). These modes are present in both iPhone and Android phones. They allow granular control to silence all but essential calls, mimicking an unreachable phone for most callers.

How to Do It:

• iPhone: Settings > Focus > Create a custom mode > Allow calls from “Favourites” only.
• Android: Settings > Sound & Vibration > Do Not Disturb > Priority Mode > Allow specific contacts.

Pro Tip: Set a schedule to automate this during work or sleep hours.

Trick 12: Go Low-Power Mode

Some smartphones have this feature for battery management which will do the trick to make your phone unreachable. The Low-Power Mode or Battery Saver limits network activity, potentially making your phone unreachable in weak signal areas.

Here’s the Step

1. Go to Settings > Battery > Battery Saver.
2. Toggle on Battery Saver.

Note: Effectiveness depends on device and signal strength.

Trick 13: Third-Party Call-Blocking Apps

If you still can’t figure out how to make phone not reachable, advanced call blocking might help. Reputable apps like Google Dialer or Hiya offer advanced call blocking, letting you filter calls to appear unreachable. Be cautious of privacy risks with unverified apps.

Steps:

1. Open Google Play Store (Android) or App Store (iOS).
2. Search for “call blocking” and choose a trusted app (e.g., Google Dialer, Hiya).
3. Install and follow setup instructions to block or screen calls.

Note: Check app permissions to protect your data.

Trick 14: Use Data Connection

If you have a data pack, this trick can help. In fact, you don’t need any complicated functions to know how to make phone not reachable. Start downloading many files using different browsers to jam your network. This will make your phone appear unreachable to callers. Note: This won’t work if you’re using Wi-Fi.

Also, practically speaking, it can be a hassle for someone who is just trying to focus on work at the moment. So, choose this option only when nothing else is working out!

Trick 15: Use Tools

You can use a cell phone signal blocker pouch to jam signals. When your phone is in this pouch, it will appear unreachable to callers. However, understanding how to make a mobile not reachable can help in managing calls without blocking anyone.

Trick 16: Temporarily Disable the SIM Card

You can temporary disable your SIM card if you want to make your phone unreachable. When you do so, your phone will no longer connect to cellular networks. Therefore, you will not receive any incoming calls, messages, or notifications. However, you can still use other functions of your phone.

Follow the steps below to disable your SIM card on different devices.

Trick 17: Jam the Network

If you want to make your phone unreachable, overload your data connection. You can do it by downloading multiple files simultaneously. It can make your phone appear unreachable temporarily. It is effective when using mobile data instead of Wi-Fi.

• Open multiple browsers or download managers on your smartphone.
• Start downloading large files at the same time.
• It increases the load and data traffic, which may cause your phone to become unreachable for incoming calls.

Trick 18: Remove the Battery

If your phone has a removable battery, take it out when your device is still on. It makes your phone unreachable till the time you insert the battery again and restart the device.

• Remove the back cover of your phone.
• Remove the battery while the phone is still powered on.
• Wait for the moment before reinserting the battery.

Keep in mind that this method works only for phones with removable batteries.

Trick 19: Use the Signal Blocker Pouch

A signal blocker pouch is popularly known as a Faraday bag. It is specifically designed to block all electromagnetic signals that reaches to your phone. All you need to do is place your device inside this pouch. By doing it, you can effectively make it unreachable.

• Purchase the top-quality signal blocker pouch from the reliable vendor.
• Put your phone inside the pouch whenever you want it to be unreachable.
• Remove the phone from the pouch when you want to restore connectivity.

It is useful when you want to ensure complete privacy or when entering secure facilities that prohibit mobile devices.

Extra Tips: Pick Your Trick With Caution!

These strategies are perfect for staying unreachable when necessary. However, each comes with its own set of advantages and drawbacks. Consider these tips before implementing any on your phone on how to make phone not reachable:

Choose what you need

• Do Not Disturb: Good if you just want silence.
• Airplane Mode: Stops all calls and internet.
• Call Forwarding: May look like you’re avoiding someone.

Know the downside

• Some settings (like Airplane Mode) turn off more than just calls. They also stop the internet.
• Your phone already has built-in tools. Use them instead of random apps that may not be safe.
• Don’t misuse these tricks to lie or ignore people unfairly. Use them for rest, quiet time, or focus.
• Try it out by calling from another phone to see if it works as you expect.

How To Reduce Unwanted Calls?

If making your phone entirely unreachable feels too extreme, here are some effective tips to reduce unwanted calls:

• Register for DND (Do Not Disturb): Text “START 0” to 1909 (in India) to block telemarketing calls directly through your carrier.
• Enable Spam Detection: Turn on the built-in Caller ID and spam filter settings within your default Phone app to automatically flag suspicious numbers.
• Limit Number Exposure: Be cautious about where you share your contact details. Avoid posting your number on public platforms or filling out unnecessary forms.
• Report Spam: Actively report spam numbers using third-party apps like Truecaller or through your specific carrier’s app (e.g., Airtel Thanks, MyJio).

How To Stop Calls On Landline?

How To Stay Connected to The Internet While Appearing Unreachable

Do you ever want to browse, watch videos, or use apps without being disturbed by calls, texts, or appearing “online” to contacts? If that’s a big yes, there’s a popular workaround to try out. Use your phone’s Airplane Mode (also called Flight Mode) in a clever way. This trick is especially useful for dodging notifications while still enjoying Wi-Fi-based internet acces

1. Enable Airplane Mode: Swipe down from the top of your screen (on both Android and iOS) to open the Quick Settings panel, then tap the Airplane Mode icon. This instantly disables cellular calls, SMS/MMS, and mobile data.

2. Immediately re-enable Wi-Fi: While Airplane Mode is active, turn Wi-Fi back on from the same Quick Settings panel or your main Settings app. Connect to your available network as usual.

What happens next?

Your phone is now offline from the cellular network (no incoming calls or standard texts), but fully online via Wi-Fi. Apps like WhatsApp, YouTube, Instagram, browsers, email, and most internet-dependent services work perfectly.

Key Benefits and What It Actually Blocks:

• Calls and SMS are completely blocked: No rings, no delivery of regular text messages.
• Internet access remains intact: Stream videos, browse the web, download files, or use data-heavy apps without issues.
• Appearing “unreachable” on messaging apps: On WhatsApp, for example, you won’t be shown as “online”. Or update your “last seen” timestamp in real time because the app relies on an active connection to report status.
• Other apps: Some apps might briefly sync status when you toggle modes, so force-close WhatsApp before reconnecting if you’re extra cautious.

Behavior can vary slightly by device (Android vs. iOS), WhatsApp version, and settings. If you’ve set “Last Seen and Online” to “Nobody” in WhatsApp Privacy settings, this trick combines well for maximum invisibility. The good thing is battery life often improves slightly.

Pros And Cons Of Making Phone Unreachable

When you make your phone unavailable, it reduces interruptions. Therefore, you can focus on your work. However, you may also miss important calls while doing it.

What Happens To Missed Calls Or Messages When Phone Is Unreachable?

You won’t get real-time notifications, but once you reconnect:

• Missed call alerts may show up.
• SMS/messages are delivered when the signal returns.
• Some carriers (like in India) log missed calls via apps (e.g., Airtel Thanks).

Troubleshooting Tips

If you have any issues while following the above steps, you can try out these amazing fixes:

If you are still getting calls while on Aeroplane Mode

You have to make sure Wi-Fi calling is turned off. Sometimes it lets calls come through even when Aeroplane Mode is on! So, when you are using Aeroplane Mode, you have to be mindful of turning off this setting.

If Call Forwarding is not working for you….

If call forwarding is not working, you can check with your mobile operator. They can help you see if they allow call forwarding. Also, ensure you set it up correctly. There are certain codes that can let you quickly check it.

If you cannot change Network Manually

This is quite a common issue that people face. To solve this, you can try restarting your phone. Please make sure you are in a place where more than one network is available. So, if you are in a place with a limited network, this issue can occur.

If you miss some important calls

If that’s the case with you, please don’t forget to check your voicemail and call history often. This way, you don’t miss anything important.

If Call Blocking apps are not working for you

You can look at the app settings and make sure it has permission to block calls. Make sure that you always keep these apps up to date from the Play Store or App store if you are using an iPhone.

Difference Between “Busy” And “Not Reachable”

When you call someone and hear a busy signal, it usually means that the person’s line is currently in use. This indicates that the number is active and reachable, but the recipient is already on another call. You can try calling again later, and it’s likely the call will go through once their line is free.

On the other hand, if you hear a “not reachable” or network error message, it suggests that the number cannot be contacted at that moment. This could be due to several reasons: the phone is switched off, out of network coverage, or call forwarding has been set to an invalid number.

Interestingly, if you want to avoid calls from a specific person without outright blocking them, forwarding your calls to an invalid number is more effective than simply blocking. While blocking may trigger a “busy” signal, forwarding to an invalid number simulates a network error. To the caller, it appears as if your phone is not reachable, giving a more subtle way to avoid calls without alerting the person.

This distinction is useful when managing personal or work-related calls. Knowing the difference between “busy” and “not reachable” can help you control accessibility, avoid unwanted interruptions, and handle communication more discreetly.

How to Schedule Your Phone to Go Unreachable Automatically

You don’t have to turn settings on and off every day manually. Both Android and iPhone let you automate this.

On iPhone:

Here are a few steps you need to follow on an iPhone.

Go to Settings > Focus > select a mode (like Sleep or Do Not Disturb) > tap “Add Schedule” > set your preferred time. Your phone will automatically silence calls during those hours every day.

On Android:

Go to Settings > Digital Wellbeing > Bedtime Mode or Focus Mode > set a schedule. You can also use the Do Not Disturb schedule: Settings > Sound > Do Not Disturb > Schedules > add a time-based rule.

Once set, you don’t have to think about it again.

What Does the Caller Hear When They Call You?

What a caller will actually hear is completely depend on your network operator and which trick you use. Let’s understand them in a brief.

Here, one thing you need to keep in mind is that DND and Focus Mode only silence your phone. The caller still hears it ringing, so if you want to appear truly unreachable, use Airplane Mode or disable the SIM instead.

Frequently Asked Questions

How do I make my phone unreachable?

To make your phone unreachable, enable Airplane Mode, disable mobile network manually, or remove the SIM card. These methods stop your device from connecting to cellular networks, causing callers to hear “not reachable” or “switched off.” This is useful when you want complete disconnection without physically powering down your device.

Can I make my phone unreachable without turning it off?

Yes, you can make your phone unreachable without turning it off by enabling Airplane Mode or disabling cellular service in network settings. You can still use Wi-Fi for internet access while calls and SMS remain blocked. This allows you to stay online while preventing incoming calls from reaching your number.

What does #002# do on a phone?

Dialing *#002# cancels all call forwarding settings on most GSM networks. It disables unconditional forwarding, busy forwarding, no-answer forwarding, and unreachable forwarding. This code resets your call diversion settings to default, ensuring calls ring directly on your phone instead of being redirected to another number or voicemail service.

How to set phone to not receive calls?

To stop receiving calls, enable Do Not Disturb mode, block specific contacts, or turn on Airplane Mode. Do Not Disturb silences calls while allowing exceptions if configured. Blocking prevents selected numbers from reaching you. Airplane Mode stops all cellular communication, ensuring no calls come through while still allowing offline device use.
