First off, when a blocked number tries to send you a text message, it won't go through, and they will likely never see the “delivered” note. On your end, you'll see nothing at all. As far as phone calls are concerned, a blocked call goes directly to voice mail.
Moreover, how do you call someone if they have blocked your number?
Method 1 Calling From Your Own Phone
- Disguise your caller ID. This keeps the receiving phone from knowing who is calling.
- Dial *67. This code will block your number so that your call shows up as an "Unknown" or "Private" number.
- Download an app that gives you a random phone number.
- Call a landline.
- Change your number.
Can you call someone on Whatsapp if they block you?
When someone has blocked you in WhatsApp, then you can no longer communicate with that person through WhatsApp's features (ie Chat or Voice call). Using other means such as text messages or plain regular cell phone calls would keep on working as those have about nothing to do with WhatsApp.
