WhatsApp is the most used instant messaging application in the world. Many users use it to communicate both with family, partners, friends or to study and work.
And surely it has ever happened to you that you cannot access the information of a contact, right? Well these may be the reasons.
One of the reasons could be that this contact has configured their account so that nobody can see their profile photo or personal information.
But you can also have the setting activated so that this information is visible only to your contacts, so if the user did not add or delete you, you will not be able to see it.
Another reason may be that this contact has you blocked on WhatsApp. If so, not only will you not be able to see their information, but they will also not receive your messages or calls.
