I am on $15 base plan for texting. I added a talk booster. I also signed up for $5 automatic top-up for calling.
Some months I would like to top-up for US roaming instead. How do I change this?
Under "Manage Automatic Top-ups" The only option I see is to STOP a top-up, or to change the AMOUNT of current top-up.
Do I cancel the current one and add another for each change?
