How Can I Spy on a Cell Phone Without Installing Software on the Target Phone?


Spying on someone’s phone without them knowing may seem a bit far-fetched and sci-fi kind of thing that we usually see in movies or read in popular spy novels, but it’s not in reality. It’s very much possible to spy and monitor a third-party phone if you know how to do it.

In today’s article, we will talk about how to spy on a phone without installing any software on that device. Yes, no matter how unlikely it may sound, it’s very much possible, and the best part is – you can do it without paying for anything.

There’s no need to buy expensive premium apps, you can achieve the almost same result with free software, or software with a free trial period.

But before we start, let’s have some words of caution. While spying on somebody is quite thrilling, and people mostly brag about it – you shouldn’t try to track anybody’s whereabouts by monitoring his/her cell phone as it’s strictly prohibited in almost every country.


It’s a severe violation of a person’s right to privacy, and you can law is very harsh in such cases. In short, it’s unethical and illegal to monitor a third-party device without the owner’s consent, unless it’s your minor kid and you want to monitor his/her online activities.

Or, perhaps you want to monitor your employees to make sure they are not involved in any kind of activities that can harm you at the professional level. Except for a few such cases, you better not try the methods we are going to discuss now.

This article is purely for educational purposes, and we do not encourage any illegal use of the methods described here. If you understand the legal consequences it may cause in case of any non-intended purpose, you can proceed to the next part of this article.

Can you really spy on a smartphone without even having to install a software in the phone?

In one word, Yes. You most certainly can spy on a cell phone remotely, and there’s no need to install software on that phone manually. That means you can very well monitor a phone even you aren’t able to get hold that phone for once. So, the question is – how?

A few Android spy apps offer this remote spying of a smartphone feature, and some even provide a generous free trial period. And although they all may not have all the features you’re looking for – a free trial period means you’re not paying a cent unless you’re fully satisfied with the result that spy app promises.


Today we will talk about the top two Android and iPhone spy apps that you can buy right now. But as we already promised, these two apps offer trial periods as well so that you can test their functionality extensively before committing to a long term plan.

So, without wasting more time, let us see what features these two apps are offering, and where they are different in terms of functionality, convenience, number of useful features, and of course, the cost.

Our first app is mSpy, which you can use to monitor a device without having to go through the hassle of installing the software on that phone. You might be wondering how it’s possible – let’s explain.

How to spy on someone’s phone using mSpy?

mSpy is a leading mobile tracking and monitoring app. Thousands of people all over the world use this tool to monitor cell phone activities, and if we go by the revving reviews in various online review sites – they are quite satisfied with the result.

There’s no obligation to buy the tool initially, you can use the free trial version to check its features to decide if this is the right tool for your specific needs. Go to their official website and sign up for a trial account there.


Once you’re done, now let’s proceed to the next part – how to spy on a phone remotely even if there’s no way to get hold of the phone physically.

After successful signup, you want to download and install the main mSpy app on your phone. Now, once installed, log in to the software using your credentials, and fill the vital personal information of your target phone owner.

You will be required to put valid data of your target person (they do it to ensure you’re not spying a random person you don’t know personally), like name, age, and the type of device he/she uses and you want to monitor.

Here’s one thing you should note, though. The device you’re targeting to spy on must be connected to the internet. If it’s an offline device mostly, then you’ll not get the monitored data as it solely relies on the internet connection for communication.

  1. First of all, sign up on the mSpy website to get a account.
  2. Log in to the app and submit all the personal info (not yours, the target device owner) that you’ll be asked.
  3. Now, you need to know iCloud ID and the password of the target phone, and put those details in the appropriate field, and tap the “verify” button. Here you want to make sure that the iCloud backup and syncing service must be enabled in the target iPhone, without which the verification process will be failed, and this method won’t work.
  4. If everything you have done as per the instructions, there will be a “successfully verified” message. Until that message appears, you should wait as it can take up to a few minutes, sometimes depending on the network speed in your device and the target phone.
  5. Now, you can access your account dashboard. Give it a few more minutes to sync the data from the target iPhone.

Although mSpy is a fantastic app to spy on iPhone remotely, the next app we are going to talk about is far more interesting in terms of features and convenience. It’s NEXSPY which is a next-gen spy app without target phone.

Not only smartphones, but NEXSPY also supports almost any user device that we use to connect the internet, like PC, Mac, and iPad. Its unique feature set and versatility made it the number one choice of a vast majority of the best spy app for android without access to target phone enthusiasts worldwide.

How to spy on a smartphone even if you have no physical access with NEXSPY?

With NEXSPY, you can easily monitor the device from anywhere in the world, even if you can’t get its access manually. It works with any Android phone. However, this particular way of remote spying is not officially supported or encouraged by NEXSPY.

Unofficial remote spying method with NEXSPY

Before we proceed, please remember that you are not going to get any official support from NEXSPY if you get any problem monitoring the device if you follow this method, as we mentioned already, it’s unofficial. But don’t worry, this is a tried and tested method and lots of people are already spying using this method.


First, collect a hilarious meme or any image file. Make sure it’s a fascinating one so that people would tap to see it.

Now, bind the NEXSPY apk file with that image file. Binding the .exe file with the image file will make the .exe file invisible to the untrained eyes. Hence, once the target person taps on the image, the .exe file starts getting installed behind the scene.

Send the image file to the device by WhatsApp or email, and then let’s hope the target person will find the image interesting and will tap on the same. Once he/she touches the picture, the hidden .exe file will be installed silently in the target device and will remain hidden until and unless the device gets factory restored.

NEXSPY – Main features

Call and SMS monitoring

This is a standard feature that every sms spy app provides. The entire call and message log will be synced with your account control panel. If you want to know who the people are talking (or messaging) to your target person, this is the feature you’re looking for.

Internet browser history

If you enable this option, you’ll receive a real-time screenshot of the target device. You will know what website or app the target person accessing at that very moment.

Messaging apps monitoring

People don’t use standard SMS as much as they use various messaging apps, like messenger, WhatsApp, etc. NEXSPY can monitor those third-party apps and send you logs in real-time.
