Hi, I just setup an prepaid account for my mom who is a very light (we're talking 10-20 minutes /month) user and will take forever to use up the minute voucher that was just purchased.
I just topped up her account with a $25 500 minute voucher and it will obviously last very long based on her usage. However, do I need to put in money every month (or 90 days?) to top up her account in addition to her $15 base fee? or can she basically pay her $15 fee every month and top up only when she uses up her minutes?
Please let me know.
