Is it possible to book additional volumes?

Purchasing additional data is possible, and it’s very easy. Once the 500 MB included in the 1NCE Lifetime Fee have been used up, you can simply purchase another 500 MB for 10 euros (net). The activation period of 10 years remains the same. For each SIM card reaching 80% of the volume included in the 1NCE Lifetime Fee (500 MB), the customer will automatically be notified of this, including the option to book an additional 500 MB.
