The website advertises the 250 mb bonus for the $15 plan but it doesn’t say anything about the bonus when I go to change to the $15 plan through my account. Below is from the website.

And below this is from the Change Plan page of my account. As you can see, the $25 dollar plan has its data bonus mentioned, but the $15 dollar plan does not. Is there any way for me to get the 250 mb bonus on the 15 dollar plan?
