You do not need to 'select' an active reward on your account to use it for data connectivity. If your haven an available reward that is valid in your current location, Roamless eSIM will automatically start consuming it.
Automatic Prioritization
Roamless eSIM has an automatic prioritization logic for providing you with data connectivity:
If you have rewards in your account, the eSIM will always prioritize using your rewards, as long as they are valid in your current location
Once your rewards are consumed, then Roamless eSIM checks to see if you have a valid data plan for your location -and if it's available, consumes the data plan next
Once the data plan is fully consumed (or expired), Roamless eSIM then consumes your pay-as-you-go credits
This process is all automatic and controlled by the Roamless eSIM, based on your current location and what you have available in your account (rewards, data plans, credits).
Maximizing Value
Your rewards (except referral rewards) all have expiration dates. So they get consumed first to make sure you get the most value out of your rewards before they expire
Similarly, your data plans also have 30-day validity, so they get consumed after your rewards
Since your purchased Roamless credits never expire, they always get consumed last
