When using my ipad, I can receive text messages from say my son, sister, and other individuals. Now the problem is that if I say go to Amazon to make a purchase, I have it set up for the two step verfication , where they send me an otp, one time password. I can receive that password on my iphone, but not on my ipad, why and what may I do so I can receive it on my ipad. My older ipad would receive it, but the new one will not.
