As already mentioned a few lines above, you must know that tracking the activities of others on WhatsApp, primarily private conversations, using only a user's phone number, is practically impossible. Luckily.

The only thing you can do, therefore, is to try to monitor some information and user activity of your interest, accessible to anyone with his number (or almost). Below you will find explained in detail how to proceed.

Let's go straight to the point and see how to spy on WhatsApp knowing only the phone number for free, taking advantage of some practical measures that will allow you to see the login information of the person of your interest, his profile photo, etc. Please note, however, that some data may not be accessible: it depends on the privacy settings used by the person in question.

Status online

See it been online on WhatsApp it is an operation that is always feasible. Currently, in fact, the wording "Online", which appears when you connect to the famous messaging app, cannot be hidden with any privacy setting and is always visible (even in the case of people who do not have our number saved in the address book ). The only time you can't see if a person is online is when you are blocked by that person.

It must be said, however, that to see when a person logs in to the famous messaging app, it is necessary to constantly monitor his account, as the platform does not integrate a function that sends a notification when a user makes the access (there are third-party apps that promise to be able to do this, but they don't work and, on the contrary, they pose a risk to your privacy).

To check a person's online status by acting on the smartphone, start WhatsApp on your Android device or on your iPhone, go to the tab Chat, fai tap sull'icona della white speech bubble on green background placed at the bottom right (on Android) or on the symbol of pencil with paper located at the top right (on iOS) and select the contact say your interest.

If you use WhatsApp on PC, however, after clicking on the comic or your quella della pencil with paper at the top left, click on contact say your interest.

On the chat screen with the person whose activity you want to monitor, you will see the wording Online above, under the name of the contact, as soon as they log in to the famous messaging app.

Last access

Do you want to see the date and / or time of Last Access to a person's WhatsApp? Then keep in mind that this is only possible under two conditions: the user must not have hidden their last access and you must not have hidden your last access.

For a principle of reciprocity, in fact, you are not able to see the last access of the others if you hide your own. Also, if you are not in the contact list of the person in question, they must have set their last access to the option “Everyone” in order for you to see them.

The procedure relating to the view of the last access is practically the same as I indicated in the previous chapter, relating to the viewing of the online status of a WhatsApp contact.

On the chat screen of the user of your interest, then try to see if the wording is present Last accessed [today, yesterday or date] at [time], above, under the name of the latter.

Please note that if you do not see the data in question, the person may have decided not to make their last access public or, even, they may have opted to block your account.

Profile photo

La profilo's photo of a user, may provide you with valuable information about their account, such as their identity (if they have set one in which their face is clearly visible). Let me tell you how to see it.

If you want to act, give it smartphone, after opening WhatsApp on your Android or iOS device and going to the tab Chat, premi sull'icona della white speech bubble on green background (on Android) or on the symbol of the pen with paper (on iOS). Then, if the profile photo is visible, to see it in its entirety you have to press on its miniature (on Android) or you must first press on name of the contact and on miniature of the photo in question (on iOS).

If you use WhatsApp on PC, instead, after clicking on the symbol of comic or the icon of pencil with paper (top left), click the contact of your interest and click on miniature of his profile photo (above, in correspondence with his name).

Did you follow the above procedure but were unable to see the profile photo of the person in question? Keep in mind that he may have decided to remove it, he may have hidden it from those who are not among his contacts or from everyone (through the appropriate privacy options offered by WhatsApp) or, again, he may have blocked you.
