Prepaiddatasimkaart.nl sells international data sim cards and eSims.
The sim cards and esims have identical data prices and data packages.
You choose a SIM card, or an eSIM if your device is suitable for this.
You buy a SIM card or eSIM with or without credit. You must have balance on the sim to use it. You can later order credit and have your SIM card/ESIM topped up.
You can always leave your SIM card active and/or use the SIM with a data package.
If you always want the sim active, the sim has a monthly fee of 1 euro.
If you want to use your sim with a data package, there are no fixed costs. The sim is active only during the validity of the data package.
If you do not use a data package, the normal data rates apply. In this case there is also a monthly fee of 1 euro/month.
You can always leave your sim active, and use data packages when needed. Data is cheaper with data packages.
