It is some days since you texted them on WhatsApp but they have never replied back your text. What could this really mean?
Apparently that person has blocked you or they have not been online for the past days.
Blue checkmarks indicate the person had received the message but they don't want to respond.
Here are signs that you have been blocked on WhatsApp;
1. Try calling the user
Give her or him a call on WhatsApp to find out if they have really blocked you.
It could only mean they have blocked you if the call stops precipitously or doesn't ring at all. However, this doesn't always indicate that they have blocked you. A person may resort to disable voice calls on their WhatsApp.
2. Look at their WhatsApp profile pictures.
The profile won't change to you when you have been blocked. Tap their profile and see if it is displaying any change. If you can't see either of their status or profile photos, they may have blocked you.
3. Look for the Last Seen timestamp
The last seen stamp will always appear on someone's profile if they are not online. Some disable this feature for various reasons like privacy.
However, if you have not been able to see this info, this could as well be an indication you were blocked by that person.
