Changed my phone number, still sends text as my old number

[craigler]

I changed my phone number on March 10, and it's still sending txt as my old phone number. When someone sends me a txt on my new number, I do receive them.

When I call someone, it shows my new number and when someone calls me on my new number, it works as well.

I have a Samsung S24 Ultra.

Any help is appreciated!

Are you using Google Messages or the Samsung SMS app?

In Google Messages go to Messages settings -> Advanced -> Phone number and update it.

The Samsung app should have a similar setting.
