How long do I have to wait to change my plan since I'm using an affordable phone?

It hasn't been long since I signed up.

You can usually change it once a month.

It could be an agreement or something.
Something like you can't change your plan until a few months after you sign up.
I think there was a limit of 90 days or 3 months.
