I have been getting these pop up ads on my phone that seem to be linked to my phone number. I went from a Samsung Galaxy S9+ to an iPhone 11 Pro Max and I had to transfer the sim cards. The same thing was happening on my Samsung and now it is happening on my iPhone. The pop ups are similar to a the pop you get when you run a SMS code that usually comes with some mobile service providers. How can I get rid of this?
