I am planning to add-on a monthly long distance to call the USA. It is $3/month and $0.05/minute.
This add-on is per month at the moment I add it Or is it goes per bill cycle.
example,, Add-on January 1 st, 2022 $3, the next month is February 1, 2022 $3
or
Add-on January 1,2022 $3 but my Billing cycle ends in January 11,2022 so Do I have to pay another $3 on January 11,2022? Or only $1.50 per half of month?
I hope someone can answer my question
