Not receiving Whatsapp activation codes on i phone 13
Hello, I am not receiving the Whatsapp activation codes on my i phone 13. I tried the text and voice, none works. It says, "Can't send text to your number" and when it comes to voice calling, it says, "Can't call your number, please check the number." I checked my new sim, sim works just fine, nothing wrong with the sim. I tried with a different sim, still doing the same thing. I have updated the software IOS 18, nothing working. I called my carrier, they checked the number, my sim is good, nothing wrong with the sim.
Is this something to do with the set? May be a software issue?
iPhone 13, iOS 18
