What is he blocked my number?

"I blocked my number" is oftentimes used to refer to a feature found on many smartphones and other mobile devices that allows users to prevent their phone number from being displayed when they make outgoing calls. This feature is commonly known as "caller ID blocking" or "blocking your number."

There are a few different reasons why someone might choose to use caller ID blocking or block their number when making calls. One of the most common reasons is privacy – by blocking their number, a person can prevent others from knowing who is calling them. This can be particularly useful in situations where someone wants to make an anonymous call or protect their personal information.

Other reasons why someone might block their number when making calls include avoiding unwanted calls, avoiding telemarketers, and preventing certain individuals from being able to contact them.

Overall, using caller ID blocking or blocking your number when making calls can be a useful tool for protecting your privacy and preventing unwanted calls. However, it's important to note that some individuals or organizations may not accept calls from blocked numbers, so you may need to be mindful of this when using the feature.
