Cannot Send Texts After Phone Number Transfer

[Chuu10]

I cannot activate my phone number on Message (Apple).

I tried resetting everything on my phone and nothing worked. It appears the issue is not with Apple as my email activates okay on Message, but my number cannot activate.

I realized that the number Public Mobile is using to communicate with me is the number I had before my number transfer, ending in 569:

But my transfer has been completed in Dec and my current number on my profile is 3540: 

I can use my phone to call with the number ending in 3540, but it just won't activate on Message. Please help me fix this.

@Chuu10  Remove the number in iMessage reboot the phone and add the ported in number to iMessage see if that helps
