Purchasing additional data is possible, and it’s very easy. Once the 500 MB included in the 1NCE IoT Lifetime Flat have been used up, you can simply purchase another 500 MB for 15 USD (net). The new volume is available as soos as the payment is registered at 1NCE. The activation period of 10 years remains the same. For each SIM card reaching 80% of the volume included in the 1NCE IoT Lifetime Flat (500 MB), you will automatically be notified of this, including the option to book an additional 500 MB.
