When does the validity period of my DataESIM plan commence?

The validity period of your DataESIM plan (e.g., 7, 15, or 30 days) is precisely engineered to begin only when your eSIM successfully registers and connects to a supported local mobile network in your destination country. This precise activation mechanism means you can purchase and install your DataESIM weeks or even months before your departure. The countdown for your data plan will not initiate until your device actively establishes a connection, for example, upon landing at Paris Charles de Gaulle Airport or crossing into Switzerland, ensuring maximum utilization of your purchased data allocation.
