Why Can’t I See Someone’s Profile Picture On Telegram:
Below are the reasons why can’t you see someone’s DP on Telegram:
1. Its Privacy settings
If you see that you can’t view someone’s profile picture on Telegram, it could be because of their privacy settings. This means that the person has chosen to restrict their profile picture visibility to a specific group of people or contacts.
So, if you’re not included in that chosen group, you won’t be able to see their profile picture. You should respect their privacy preferences and understand that they have the right to control who can view their information.
2. Contact not saved
When this happens, it’s possible that you haven’t saved the person’s contact on your Telegram. Due to this, Telegram treats you as a stranger, and the person may have set their privacy settings to only allow profile picture visibility for their contacts.
This can prevent you from seeing their profile picture. You must save their contact on your Telegram to gain access to their profile picture and other information they choose to share with their contacts.
3. Blocked by the contact
If you find yourself unable to see someone’s profile picture on Telegram, it could be because the person has blocked you. For this reason, they have intentionally restricted your access to their profile picture and communication.
Now, you can’t see their profile picture or interact with them through Telegram. You can respect their decision and focus on maintaining positive connections with others.
How To Know If You’re Blocked On Telegram:
You can find out if you’re blocked by seeing the profile and the changes that happen there.
✅ You will Notice: If You’re Blocked
🏷 From Your profile:

You can search by yourself and see the differences to be sure if you’re blocked by someone or not on Telegram. You’ll need to be sure that you’ve saved the number of your contact book and then open Telegram. Search for the user by his name. If the results don’t show the profile of the user with no existing display picture it means that the user has blocked you.
However, you’ll need to use another device to check and be sure about it.
🏷 From Other’s Profile:

You need to save the phone number of the user on another device on which you have a second Telegram account. From the second Telegram account, you need to search for the person by his contact name. If the person’s Telegram profile appears in the results and even shows a display picture, it means that the person has blocked your primary account.
If you don’t have a second device or a second Telegram account, you can use your friend’s mobile to save the number and check it.
✅ You will Notice: You’re not Blocked
🏷 From Your Profile:

When you’re unable to find the person on Telegram or unable to see the display picture of the user, it doesn’t always have to mean that the user has blocked you on Telegram because there is a possibility that the user might have deleted his or her Telegram account.
You need to first search for the user and see if you can find his account from your primary profile. If you can’t find the Telegram account of the user don’t be sure that the user has blocked you unless you confirm it using another device.
🏷 From Other’s Profile:

On another device, you’ll need to save the phone number, then open Telegram and search for the user’s profile. If you can’t see any display picture or find any Telegram account associated with the number after searching, it means that you’re not blocked but the owner has deleted his Telegram account.
When You Block Someone On Telegram What Do They See:
You would notice these things below:
1. Would not Find Your profile

If you’re suspecting that someone might have blocked you on Telegram, you need to check it for yourself by taking the clues. When someone blocks you on Telegram, you won’t be notified by Telegram but there will be some changes that will help you know that the person has blocked you.
The very first change that you would notice is that you won’t be able to find the user’s profile on Telegram. The profile will not appear to you on your Telegram contact list and you won’t be able to find the profile even by searching.
As Telegram is a messaging platform, it allows its users to block those contacts that are harassing and disturbing. When you’re blocked by someone on Telegram, it will prevent you from contacting the person in any possible way on the Telegram platform.
2. Can’t add You on Telegram Groups

Telegram allows users to create groups on the platform where they can have a conversation with others. But when someone blocks you on Telegram, then you won’t be able to add him or her to any Telegram groups. When you’ll try to add her, the list will not show the name of the user so you can’t add him.
Telegram provides certain privacy options to users regarding adding a person to Telegram groups. You can restrict someone on Telegram from adding you to groups even without blocking the user too.
3. Can’t see Your DP

Telegram won’t allow you to see the display picture of the person who has blocked you. When you’re blocked by someone on Telegram, the display picture of the user will automatically go blank and instead of the display picture, you’ll be able to see the initials of his or her name.
However, if you are unable to see the profile picture of a Telegram user, it doesn’t necessarily mean that the user has blocked you. It’s also possible that the user has removed the profile picture or restricted you from seeing it. Telegram allows users to make exceptions and restrictions for people whom he or she doesn’t want to show their display picture. So, if someone restricts you from seeing their profile photo, then it won’t appear to you even if the person hasn’t blocked you.
4. Can’t send messages

When someone blocks you on Telegram, you won’t be able to send a message to the user. The previous chats will appear on the chat list but if you try to open and send a message, the message will not be delivered to the user and will stay sent. It will show one tick mark next to the text which means that the message isn’t delivered.
If you find that your text is not being delivered to the user, there is a good chance that the person might have blocked you. When you’re blocked by someone on Telegram, you won’t be able to contact the person on Telegram via messages or by sending Telegram calls. If you try to call a person who has blocked you, the call won’t reach him or her although it will appear Calling to you.
