[Prepaid] Upgrading base plans and ALSO signing up for automatic top-up.
Hello. I want to upgrade my base plan from the $15/month to the $30/month. This plan states that I get 500 MB + 500 MB of data if I sign up for automatic top-up.My question is, in what order to I do these actions? Must I first upgrade the base plan, which would immediately charge me the $30, or do I sign up for automatic top-up first?If the former, I am guessing I would not have the extra 500 MB for the first month at minimum. If the latter, the automatic top-up may or may not work for the first month because it assumes I’m still on the $15/month plan. Anyone have any ideas?
