You can start using your subscription as soon as your purchase is completed!
It's important to know that each week on Cambly begins again on Monday.
So, for example, if your plan allows you to chat for 3 days per week, you can choose any 3 days during the week (from Monday until Sunday). It's up to you! Once you start talking on one day, you must finish using the day’s remaining subscription minutes on the same day. If you chat for 10 minutes on Tuesday, you must use the remaining 20 minutes before 3 am (technically, this is early on Wednesday morning), otherwise those minutes will expire at that time.
