Look at your signal strength bars. If you see two rows then Ride Mobile is activated on your phone.
If you are still unsure, go to the My Plan page in the Ride Mobile App and confirm that your plan is activated. Then check: Settings > Cellular/Mobile > Cellular Plans, and ensure your primary eSIM is selected to be your primary eSIM for data. Ride Mobile will work when your primary carrier is unavailable,

Ensure data roaming is enabled on the eSIM [Settings > Cellular/Mobile data].
