To use the Call & Text facilities of your SIM - eSIM you must have some credit in your account. This allows to debit the charges for the call and text according to our "Pay as you go" rates.
If you only purchase a DayPass Daily Plan, all your available credit is assigned to the data usage and call and text cannot be used without credit, to solve this issue you must add some credit from your member area, then the charges for the call and text can be debited.
At this time we do not offer any DayPass plan that include Call and Text. We will update you if this changes.
